Transfer Box
By Steve S.

Purchased 10/13/2021 |
Review Posted 01/08/2022

I spoke with Reliance tech support. He recommended this produce for my application. It was very cost effective compared to replacing my circuit breaker box. This is a quality product made in the USA.

I got mine installed in minimun time, clean nice install. I did have the generator connection replaced to match the common plug for portable generators. I plug the generator extension cable into the bottom of the box and the other into the generator.

Great Engineering And Easy To Setup
By Hector P.

Review Posted 04/23/2021
This transfer switch has it all, easy to install as all wires are clearly marked and color coded, it has the plug at the bottom of the unit so you can plug in your portable generator and this model is for external locations, it even has 2 power meters (1 for switch 1-5 and the second one for switch 6-10) so you can clearly see how much power you are pulling from the generator so you can balance power consumption.

RA310 Indoor Installation
By Dan H.
BEN LOMOND, California
Purchased 11/28/2020 |
Review Posted 03/15/2021

Installed it indoors in an attached garage on the back of the main entrance service panel which is an outdoor access panel. Routed wires out of bottom knockouts through two 1” rigid conduit to a 12 x 4 x 4 junction box and through the back of the junction box into the service panel via 1” rigid conduit. During power outages, the generator rolls out to the driveway, cable connects to the prewired input connector on the transfer switch. And the garage door closes over the cable keeping exhaust from entering the garage.

Good Quality Easy Installation
By Thomas F.
California
Purchased 11/14/2019 |
Review Posted 01/17/2020
Good quality, rugged outdoor transfer switch. Very easy to install, review U-Tube installation procedures first. My wife and I installed this bad boy in under 3 hours from beginning to end. Hardest part was holding it in place during securing it to our wall, it’s a little heavy and you need that third hand help.
Wiring was easy and straight forward, again with my wife’s help it made it much easier. Also have a heat gun or hair dryer available if you need to bend the plastic conduit, we did not have any knockouts on the side of our panel and needed to come in from the panel bottom, thus had to make a 90 into the box.

I'm In Love ❤️❤️❤️
By Marc C.

Review Posted 08/31/2019



this transfer switch is built to last and was super easy to install. the wire lengths were all plenty long to reach the home circuit panel. My air conditioner has two 220VAC circuits (indoor air handler and outdoor compressor) and the two transfer 9 220VAC circuits allow me to switch both easily. The additional 120VAC circuits are a breeze to setup.
I'm super impressed with the quality and durability of the steel enclosure. The line-off-generator switches are quality devices and feel great. The analog watt meters are quite convenient.
All wires were tight and wired properly. I'm super impressed with this transfer switch and have recommended it multiple times already. The whole piece is quality. This was a big part of my preparation plan for long-duration power outages. Now I can run my air conditioner, kitchen circuits with fridge and freezer, and TV room plugs and ceiling fans very easily. I have no need for automatic switch-over. Manual is great once it's installed.
Awesome transfer switch. I love it. Sometimes I go outside just to look at it. ❤️❤️❤️ Warm fuzzys all around.
