Reliance Controls Pro/Tran 2 - 30-Amp (120/240V 10-Circuit) Indoor Transfer Switch w/ Wattmeters & Inlet

This was purchased as a transfer switch for my backup generator. Once installed I can select which circuits I want in a power outage.

Installed this product DIY. I did have a couple issues that required a call to Reliance Controls. Both phone call with their support was superb. It was obvious the support team have heard everything. The first all was related to a 120/240 volt from my power source. The second issue was related to a GFCI outlet in the line I was switching. Neither issue was Reliance Control's, still the support team was able to solve my issue very quickly. Excellent support for DIYers. I was a bit disappointed though when I was trying to identify the circuit IDs (A-J). The letters were all but rubbed off when I pulled it through the flex.

Good quality components. Can replace the breakers if needed.

Labels on the wire is hard to make out, I have to open the system and tested one by one to make sure

Works great for my panel and generator. Just what I needed.

The easy to install. The wires were labeled and easy to follow instructions.

So far, so good. I tested this when the electrician installed it. It worked perfectly, but I have tested it only once. I trust it won't let me down when I need it. My electrician recommended it, so that's why I got this model and brand. It appears to be well-constructed and Reliance has a good reputation for quality.

Check security of wiring to circuit breakers before installing. Found loose connections, secured all good.

Solid construction and easy to install. The instructions were easy to understand.

My townhouse is in a hurricane/storm prone area, and it is important for me to have access to power when a storm knocks power out. I don’t have access to natural gas, so am restricted to powering my house using a portable generator. I don’t like running cords all over the place, so after Katrina I installed a 6-circuit transfer switch (Reliance Pro/Tran 20A 20216).

We lost power for about 8-10 days during Hurricane Ida. While I had a window A/C running in one bedroom, my wood floors buckled because of the increase in humidity, and it took several days of dehumidification to make them settle down again. Therefore, I decided to replace the 6-circuit switch with this 10 circuit switch, because the additional four circuits would let me run my central A/C and air-handler. Air-conditioning and dehumidifying the entire house should prevent the floors from buckling in the future. Also, I have a larger Champion dual-fuel generator (9375W/7500W) now, which is capable of running my central A/C.

My install was a little complicated because my main panel is flush mounted on finished drywall. In addition, I had to remove the old transfer switch, resize the drywall cutout, and manipulate the metal conduit between the new transfer switch and the panel in a fairly tight space.

The Pro/Tran 2 310A transfer switch came with two 20A double-pole breakers and everything else was a 15A breaker. Positions A & B can be outfit with 30A breakers, so I replaced one double-pole 20A breaker with a 30A breaker. And three of the 15A breakers with 20A breakers to match the circuits they would be powering in the main panel. The transfer switch takes standard Siemens breakers that are available from most hardware stores.

Because my installation is a flush-mount install, I had to use the Reliance flush mount kit. The kit part number is K10.

Wiring itself is very quick and takes less than 10 minutes. I recommend wiring in a type 2 SPD to protect any against potential surges from the generator.

Each circuit on the transfer switch has three positions: Line (utility power from main panel to the circuit), Off (no power to the circuit), and Generator (generator power to the circuit).

I tested the switch after installation - worked perfectly. If you plan on powering a central A/C using a generator, make sure you have a soft starter on the central A/C to decrease the startup Amps. I recommend the EasyStart, which stopped the startup Amps on my 3-ton dual-stage Lennox heat-pump from 48 Amps to 24 Amps. This is essential because most portable generators have a max output of 30A, which would be insufficient to start a central A/C. Even though their running Amps requirement is low and within the capacity of most generators.

Finally, manual transfer switches like this one are a very safe way to power a house using a generator without endangering the lives of linesmen. So please use one if you intend to connect a generator to your main panel.
