    • Electrician install no problem. Works well.
We had this installed by an electrician for our backup generator. We got the 50A version to have some upgrade option even though our generator is only 30A. The construction is decent for an indoor mount system. The box itself is metal. The little door covering the load switches is plastic. The switch handles are plastic similar to a breaker in feel. So not built like a tank but decent quality and given that it will probably only be touched once every few years - plenty good enough. There was no problem with the install. It actually took fewer hours to install than they bid which was a nice surprise. Note this is indoor installation only. This one has 10 single circuits but 2 of them are doubled if you want to use them for a 220 circuit. So you really get 2x 220V circuits and 6x 110V. This worked fine for our setup. The way this works is when it is hooked into your main panel you basically have two sources for the selected circuits in your house. Think of it as a "Y" connection connecting your house circuit to either the utility OR to the generator inlet. Each circuit in this box can be individually switched to the utility OR the generator OR turned off from both. This allows you to only turn on high-current loads such as a water heater or AC or something when you need it. Thus you can load balance your generator if all your loads together are too much for the generator. Just as a reference it cost us about $500 to get this installed by an electrician. We had to buy an $40 external weatherproof generator plugin box to mount on the outside of the house. We also had to buy a $50 NEMA L14 extension cord to go from the generator to the plug box on the house. So around $1000 for the parts and installation. ... show more

    • Cannot imagine a better designed Transfer Switch.
Review Image by curlgary
I installed flush mount recessed into sheet rock wall using trim kit, as photo shows: https://www.amazon.com/dp/B00REJVYYG?psc=1&ref=ppx_yo2ov_dt_b_product_details Very well built and well laid out to install yourself. Cables all labelled to match throw switches. Get a good layout of your house breakers before you begin, so you know which ones to run through the transfer switch. I removed the jumper for positions C&D and only used A&B for 220V. That left me 6 15 amp and 2 20 amp for other circuits. Will run everything I need plus bottom floor air and heat. Good videos on YouTube to install the Reliance Pro/Tran. Reliance Contral Products customer support is fantastic and quick. Had some questions, contacted them by email, and had answers the same day. Guenther handled my emails and was great to deal with. This is a super product, very well laid out, and very well made. Cable tails are plenty long to reach anywhere in the breaker box. I had to cut length off all of mine. Give this one a look if looking for a transfer switch. Mine will work from an outside portable generator. I ran 6-3 w/grd from the transfer switch to an outside wall plu,g to plug the generator in. Got great plug from Amazon also. It is also a Reliance Control Product: https://www.amazon.com/dp/B004HSO1JW?psc=1&ref=ppx_yo2ov_dt_b_product_details As you can see from photo I fixed a label under each transfer switch poooooosition showing the breaker number it was feeding. The only suggestion I would have to improve the box install is the have terminals to attach to for incoming wire from the gerator instead of have to splice with connectors, but was not a big issue. ... show more

    • Use a qualified electrician to do your wiring. don't attempt to do it yourself as a DIY project.
Just finished installing the 50amp 10 circuit Trans Pro transfer switch connected to my main power panel. It's coupled to a Westinghouse 13.5kw tri fuel generator. After install was complete, all the wiring done, it works like a charm. We tested out the generator using the panel. With 10 circuits available we were able to put power into 90% of the house with the only exceptions being the dish washer, garbage disposal. Since it runs on natural gas I'll have no issues with keeping fuel on hand. Just in time too because we're experiencing flooding and winter storms. ... show more

    • Good product at a fair price
The generator is solid and started up right away. I like the fact the remote was already paired and charged. Assembly was easy and the price was great for the value. Came with the oil to add to the crankcase. The controls are easy to access and use. Plenty of receptacles and optins. Overall, I am pleased so far with the product ... show more

    • Quality brand and happy to pay a bit more for it
Good quality and instructions are clear. Uses square D breakers and instructions come with a replacement parts list. On the expensive side of switches but the quality is great. The flexible conduit is a bit tight for all the wires on the 10 switch model but they can be pulled through. Installed and testing went well. ... show more

    • Works really well for solar
This is a great tool for people who want to have a fairly easy way to tie solar into a main breaker box. The box itself is robust and well made. All the connections on mine were nice and solid. The wires are well labeled and plenty long (at least for me). Mounting is also very simple whether surface or inset. I did hire an electrician to work with me on the install because I wanted to make sure things were well installed and organized in my very old main breaker box. We ran from my inverters (2 inverters for split phase 220) to the bypass box and then bypassed my heat pump water heater, the dryer (useful as a dump load) and some 110 critical loads. Now if I want to go on battery (solar), I just flip the bypass switch or switches to GEN. If my batteries get low and need to give the system a break, I can flip back to line power. It’s very convenient. The 50 amp capability means if I get larger inverters, I’m good. I ran beefy wire from the inverter junction box over to the bypass box. All I’d have to do is swap inverters and do some easy wiring and I’m golden. I’m very happy. ... show more
