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. This unit is cUL1008 listed and is covered by a 5-year warranty.

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

    • Easy install for backup power!

The media could not be loaded. 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

    • Works great! Read instructions carefully! Refer to Instruction Manual if confused!!

Purchased this so that I could use my Ioniq 5 as a back-up battery for my home during a power outage. I hired my neighbor who is an electrician to help me install the device. The device comes with 6 transfer switches, 4 are 15 amp and 2 are 20 amp. With the device, I am able to power many of the important areas of my home during a power outage using my Ioniq 5's V2L system using a cable that converts the L14-30 to household cable https://www.amazon.com/dp/B07Q42XPZT?ref=ppx_yo2ov_dt_b_fed_asin_title. The device also has 2 meters so that you can see how much load is being pulled from the devices. It is split so that the left side reads the left 3 (ABC) and the right side reads the right 3 (DEF). The device also comes with an L14-30 extension cord which appears to be pretty heavy duty, flex to house the cables and some L brackets. The device comes pre-wired (with 12 awg wire) so the only thing you have to do is wire it up to the home. Both the black and red wires are labeled AAA,BBB,CCC, etc. to match the switches on the transfer panel. The labeling is a little bit on the small side and can be a little difficulty to read. I have a few minor complaints. The first is that my electritian got confused, there was a sticker which was wrapped around the cables which had some instructions on it regarding the cables. Unfortunately we lost the sticker during installation to verify what that label said, however it caused him to install the cables in the opposite manner on the first attempt. When we did this, several of the several circuit breakers on the main panel (including ones not attached to the transfer switch) would trip when switching from Line to Grid. We ultimately consulted the diagram in the instruction manual which correctly labeled which wire goes where. Again, we lost the sticker, so I couldn't tell you whether it was the label that was incorrect, or just that the electrian mis-interpreted the label. Another minor complaint is that I had the outlet installed directly onto the switch, but when I installed it with the lid, the hinge was sitting over the DEF switches. I'm not sure if it actually interfered with their functionality or if this could be solved by flipping the hinge in a different orientation. Overall, this product works as intended. I was able to use my Ioniq 5's V2L capabilities to power parts of the house, saving a lot of money on batteries / generators. For those of you with electric cars, this is an awesome solution! ... show more
