Description

The Reliance Controls 31406CRK 30 Amp 6-Circuit Pro/Tran Transfer Switch Kit has everything you need to easily complete a portable generator transfer switch installation in a home or office. The purpose of a transfer switch is to connect a secondary power source, like your very own portable generator, to circuits in your home or building that are wired into the electrical system. Thus, it is designed to enable the wiring system of the building to accept the full power of a portable generator, which can run multiple electrical appliances and devices during a power outage. The transfer switch ensures that you can safely use back up power during a power outage without having to worry about back feeding the utility line. In an emergency situation, this kit can make all the difference. Since 1909, Reliance Controls Corporation has contributed more innovations than any other single manufacturer and has been awarded over 85 patents on manual transfer switches, time switches and accessories. Reliance Controls Corporation specializes in the manufacturing of a wide variety of electrical products. The primary product line consists of heavy duty time clocks and controls, generator accessories, transfer switches and transfer panels for portable generators. And after over a century of innovation, Reliance Controls Corporation has built an enviable reputation for high quality, superior engineering and exceptional customer service. The Reliance Controls Corporation 6-circuit 30 Amp transfer switch is a complete turn-key kit with everything needed to make a professional transfer switch installation in a home or office. It is designed to enable the wiring system of the building to accept the full power of a portable generator, which can run multiple electrical appliances and devices during a power outage. Use this transfer switch for up to 7,500-watt generators equipped with NEMA L14-20 or L14-30 power outlets. The kit includes a 30A 6-circuit prewired loadside reliance transfer switch with wattmeters; 30 Amp outdoor power cord inlet box, a 30 Amp 10-foot generator power cord with L14-30 ends, and an extra L14-20 cord end for smaller generators.

High quality and YES you CAN do it yourself.

Super easy install for a guy/gal who can handle simple DIY wiring jobs around the home. (If you can wire an outlet or a light switch you can definitely handle this install). Very high quality construction from the connections to the quality of wiring used to the feel of the switches. I appreciate the twin gauges that show me how many ways my house is pulling from my generator. ... show more

I just completed installation of my ProTran 6-circuit transfer switch. I found the wiring of the switch to the 1980's-era power panel to be quick and straightforward. Same for the wiring between the transfer switch and the outside power inlet box. Physically connecting the wires from the switch to the panel circuit breakers took less than 30 minutes, and from the switch to the power inlet box less than 10 minutes. However, the whole project took me a day and a half. My power panel is sunken, and the face is flush mounted with the garage wall, thus a straight connection between the wall-mounted switch and the sunken panel was not possible. I had to remove sheet rock from below the panel, run the conduit from the wall-mounted switch to the panel from underneath, and then patch the hole. Also, I wanted the power inlet box to be attached to the outside brick, and opposite of where the switch is installed inside the garage. I purchased some PVC conduit, a stress relief connector, and a small elbow box and ran building wire through the conduit, through the sheet rock, and through a hole I drilled in the mortar between bricks. I had to patch a little around the hole in the sheet rock to fill in a slight gap where the conduit entered. I also used a stress reliever where the wire entered the back of the inlet box, and concrete connectors to attach the back of the inlet box to the brick. Because my power panel breakers were not all identified, I took the time to verify which breaker provided power to which part of the house. My biggest challenges: 1. Working with building-grade solid copper wiring. This wire is very hard to manipulate if you cut it too short or too long. Too short and you may not be able to get all the wires to go where they need to. Too long and you may not be able to cram them into the switch box or inlet box. It took me quite a while to get this right, especially at the power inlet box. I finally figured out that cutting the white neutral wire a wee bit shorter than the others made it easier to press the inlet box front cover closed. 2. Attaching the power inlet box to the brick wall. It comes in two pieces, the back plate and the front cover. If you do not allow for space between the back plate and the wall, you will not be able to get the front cover back on. My solution was to loosely attach the back plate to the brick and then use expanding foam to provide weatherproofing and support -- and a gap. The foam provides firm support and keeps the box away from the brick just enough to attach the front cover. 3. Getting the correct adapter. The transfer switch comes with a 10-foot, 30 amp, L14-30R power cord (4 male prongs and 4 female plug slots: Neutral, Ground, Hot1 and Hot2). My Predator 3500 generator comes with a 3-slot power plug, so I had to find an adapter. I ordered a TT-30P to L14-30R adapter only to find out later that such an adapter comes in two versions: 1. bridged, and 2. un-bridged. In my ignorance I got the un-bridged. A bridged (or "tied") adapter connects Hot1 and Hot2 together so that they end up providing 120v power to both sides of the transfer switch, i.e., all six circuits. An un-bridged adapter powers Hot1 but leaves Hot2 dead. The result is that half of the transfer switch circuits remain dead. So, I ordered the bridged Reliance Controls AC3130 adapter to fix that problem. Kudos: To resolve the adapter problem, I called Reliance Controls customer support. After only two or three rings Jane answered the phone. She was very pleasant and helpful. I briefly explained my problem, and she immediately identified the bridged/unbridged issue and suggested a couple of remedies, one of which included the AC3130. I could not have been more pleased. Conclusion: This was a pleasant installation project, but had its challenges, none of which was overwhelming. For someone with moderate mechanical and problem-solving skills, and who can carefully work around electricity, I would say this project fit comfortably into the DIY category. I highly recommend the Reliance ProTran transfer switch kit. ... show more

Easy install for backup power!

Review Image by Luke
Had one too many power failures and decided to invest in a generator for our house. While this supports 6 circuits it installed super easy. Instructions were clear and easy to understand through out the mounting and wiring steps. Even with minimal wiring knowledge after watching their video, I tackled the entire install in just about an hour. Already used it twice in a month since installing. My daughter’s bigger fear is when we lose power for some reason. She can now hit the remote on the generator and then flip the switches and she won’t even know the difference! Had everything needed included and I feel is a great value! If I had to do it again I would go with the 10 circuit as I had more watts available than I thought! ... show more

Nice unit but with problems
Style: Kit
This kit is nice. You cannot beat the price if you were to get all that's included separately. Again its a very nice kit but I'm not so sure about the well built comments I read in some of the other reviews. I installed mine in about two hours. I turn back on the power feeding the six circuits that I'm feeding with the transfer switch and one by one I flipped each switch on the transfer switch to the line position. Once all of the six circuits were on I then checked around the house to see that everything had power and worked. Well, I found that my furnace and one of the two bedroom circuits were dead. You know DEAD, as in No power, dark and cold. WTF. So I'm thinking to myself, ok Ive been working for one of the largest companies on ALL OF EARTH as a electrician building industrial equipment for the last 21 years and I'm very confident that I didn't make any mistakes. But, I'm only human. So I checked all Of my connections and found that all was good. Next I made sure that none of the breakers just needed reset and found that this too was ok. Next out of frustration like you would an old tv I gave the side of the transfer switch a good smack. Well not so funny to me as it may sound to you readers but that worked for the bedroom circuit. "LIGHT ARE ON IN THE BEDROOM" my wife gave a yell. OK I don't know about the rest of you, but this to me was not acceptable. It did however give me a clue as too what was wrong. Everybody say it together now "SOMETHING IN THERE IS LOOSE". I Turned off the power to the SIX circuits feeding through the switch and removed the two screws in the case to try and see what was amiss. THERE IT WAS PLAIN AS DAY. ONE OF THE WIRES WAS NOT EVEN PUSHED ONTO ITS POST ON ONE OF THE SWITCHES AND THE OTHER WAS ABOUT TO COME OFF(bedroom circuit). Firstly, why are all of these connection made with just push on connections. We call these "fast on connection" at work. Secondly, and more importantly why are they not on there termination points. WHATS WITH THIS CRAP. I SHOULDN'T HAVE TO BE TAKING EQUIPMENT APART TO MAKE REPAIRS TO IT. Anyway, I pushed the two wires onto there termination points and closed the box up and turned the power back on. TA DA! everything worked. Are you all still with me? There's more. Anyway, an hour later the family and I return from getting lunch and wouldn't you know it. Both of the bedroom circuits are not working. I found that the two bedroom arc fault breakers in my main breaker panel were tripped. This to me automatically indicated to me that Something is loose and is, are you ready for this? Something is ARCING. Arcing is bad. Arcing leads to electrical fires under the right conditions. BUT, My arc fault breakers did there job. So again I open the transfer switch to see what was loose. I found that everyone of the push on or fast on connections were loose and needed some attention. One by one I had to remove and with needle nose pliers make all of these connections tighter by slightly closing or crushing each of the push on crimps. This is NOT something anyone should need to do on any new piece of equipment EVER. But since I was really not into the idea of tearing it all out and returning it to Amazon for a new one, only to receive another half assed unit from a company that's apparently not that concerned with quality. I decided to just make the repairs. And to add insult to injury I was disappointed to see that this shabby work was made in the USA according to the box. COME ON GUYS WERE BETTER THAN THAT. I would have expected this type of work from elsewhere on the planet. ANYWAY, that all having been said. I would have giving this Kit a five star if it weren't for these wiring issues. Its a nice kit with all that it comes with for the money. Easy to install with some basic electric knowledge and a few tools. I guess I would recommend this kit as I hope this is just an isolated case. I did write a lengthy e-mail to Reliance controls support team about my issue two weeks ago and as of this writing and have not received even a peep from them. Mmmmm. OK Ive said enough, or to much, you decide. ... show more

Excellent Product -- Can be used with 120 volt (3 prong plug) generator too
Style: Kit
This seems to be an excellent product. Easy to install yourself if you're at all comfortable working with household electricity. DVD provides excellent instructions as does the instruction book. You can view the installation DVD on youtube. Did want to pass on my experience which may be useful to others. My generator is a 120 volt with 3 prong plug. The kit comes with a four prong plug designed for 240 volt generators. If you have a 120 volt generator you can still use this transfer switch. You do need to get a 3 prong (NEMA L5-30) plug--you can get one at Amazon ( http://www.amazon.com/gp/product/B000BPARP2?psc=1&redirect=true&ref_=ox_sc_act_title_1&smid=ATVPDKIKX0DER ) or Home Depot. Connect the two hot wires to the one hot prong. Instructions on the plug will label this the black wire. On the cord supplies with the Reliance kit you'll have to cut off the 4 prong plug. The two hot wires will be red and black. The white wire goes to the white terminal and the ground to the ground terminal. This feeds the 120 volts from the generator to each of the two sides of the transfer switch. You can't power a 240 volt circuit (obvious, since we're discussing a 120 volt generator) so remove the bridge on the center two switches on the transfer switch. You don't need to be concerned with load balancing, since a 120 volt generator has only one side but you do need to be careful not to exceed your generators capacity. I did check with Reliance customer service before doing this. They concurred that it would work, and it does. Reliance should consider including this information in their instructions, and maybe include the 3 prong plug in their kit. . ... show more

I cannot say enough good things about this product and this company. I purchased this transfer switch in July of 2014 to go along with my new Westinghouse WH6500E portable generator. I am reasonably handy, and have done a small amount of electrical projects before, but by no means am I a professional. I did all the setup, installation, and wiring myself. My setup includes the portable generator with a 30 amp power cord feeding into a Reliance Controls power inlet box mounted on the house. I then installed permanent 10 gauge building wire between the power inlet box outside and the transfer switch mounted inside next to my panel. For the most part it was all very straightforward and I expected to have no problems. After initial setup I got the generator running to do a quick test. Long story short, there was a problem, and I could not run off the generator power. I struggled for 6 months to figure out what was wrong. I did various tests, but did not want to break down and pay an electrician, so I continued to hunt for the issue myself. After 6 months, I finally decided to call Reliance customer support. I was impressed to get connected to a very helpful lady from Racine, WI. Imagine that, good ole US of A customer support! She was extremely helpful, and was happy to give me her email address so I could send pictures of my setup for diagnostic purposes. We communicated via phone and email over the course of 2 days, and she quickly helped determine my issue after having me run 2 tests. The problem was entirely mine, the Reliance Controls transfer switch works flawlessly. In fact, the problem I had was a clamp that was too tight on my building wire, and was causing a short. I had arc marks on the transfer switch due to my wiring short. That did not phase the Reliance Controls transfer switch at all. The breakers on the switch and the generator worked as they should. Everything is fixed and working correctly now, thanks to the great customer service at Reliance Controls. This product is extremely robust and well designed. I would recommend this to anyone! A couple of lessons learned from my experience. Professional electricians would obviously already know this stuff, but I was learning as I went. 1) Be careful not to over tighten cable clamps, it's easy to do. 2) The power inlet cord gave me some issues. You need to make sure you really get the cord at the inlet box pushed in and turned as far as it will go. It may take a slight bit of force, but if you don't, you may only get one side of the power coming through. 3) The instructions are slightly misleading for the wiring of the watt meters in the transfer switch. Make sure you only have 1 side of the black wire and 1 side of the red wire passing through each of the watt meters. ... show more

This Reliance Pro/Tran 6 circuit Transfer switch kit paired well with my Aferiy 3840Wh Portable power station. I used a TT-30p male plug to 4 prong L14-30 female receptacle to connect to the 30-amp cord that came with kit to the 30-amp RV outlet on the backup battery. It has been thoroughly tested my me in case of a power outage and passed with flying colors :). Good length on the wires. Good instructions.

Excellent Transfer Switch
Style: Kit
Decided to purchase this switch after a week-long power outage and having to run extension cords all over the house to provide generator power. This switch is perfect for the Do-It-Yourself'er who has some electrical knowledge/experience and is comfortable working in the electrical panel. The Transfer Switch is a "Load Side" switch which prevents power from being backfed into the grid, which was a big concern of mine. The switch comes all pre-wired internally which makes installation really easy. I also purchased the flush mount kit Flush Kit for 4 and 6 Circuit Model because I was mounting it in a finished wall next to my breaker panel. The flush mount kit comes with a longer conduit which gives you a bit more flexiblity as to where you can mount the switch in relation to your breaker panel. This was very helpful. In addition, I purchased the Clear Plastic Cover Reliance Transfer Switch Clear Cover - For 6-Circuit Switches Item#s 100002 to protect the switches from getting accidentally moved. Installation is relatively easy if you take your time. It helps to have all your circuit breakers marked in advance so you know exactly which breakers control the various areas/appliances in your home. It comes with a receptacle that you can install outdoors and plug the generator into OR you can remove the outlet from the receptacle and intstall it in the front of the transfer switch. If you install it outside you will need some 10/3 wire to run from the switch to the receptacle. I'm really happy with the way it looks and the way it works. I would highly recommend this switch. ... show more
