Does The Job

Review Posted 03/11/2024
This product arrived quickly in good condition. Electrician had no problem with installation. Works great with any backup generator and will connect with any regular 3 prong extension cord. Suggest using 14 guage.

Reliance 104B1

Review Posted 03/07/2024
A very high quality product, nice design, very user friendly. Simple to install and put into use. This may be less popular as it is only a 15 amp unit. It is a perfect 'fit' for my 2000 watt inverter to power most of my 1100 sq. ft. home. Very glad I chose this one.

Perfect For Using With Honda EU220 Generator
By Peter H

Purchased 12/01/2023 |
Review Posted 12/22/2023
Easy to DIY install. Great instructions. I needed to replace the 3/5 flexible metal conduit with a loner piece, plus I added a wall inlet on outside of house. Great product!

Great Item And Great Customer Service!
By Don L

Review Posted 02/27/2023
A bit costly, but this is a quality item that is easy to install and does what its supposed to do. My installation allows me to keep a battery power station on standby for essential appliances during a power outage without the noise and hassle of a gas generator. However, should I want to run a combustion type generator in the future, this transfer switch will handle that too!

Review Posted 02/07/2023
Works great. I had no problems installing it myself. The only issue I had were that printed on markings on the black wires were not readable. I had to sort them out using my ohm meter. Someone apparently recognized the problem as the A wire had a label on it but none of the others did.

Reliance 104B Transfer Switch And Installation.
By David D
Florida
Review Posted 01/26/2023
I installed my 104B transfer switch in my 200 Amp. Square D panel. The installation was simple, and the results were excellent. I would recommend this unit to anyone looking to use a small generator to power a few circuits. I run my refrigerator and a few kitchen receptacles. These two circuits were on a double pole breaker because they share the neutral.
The other two circuits power the kitchen lighting and the Master Bedroom and bath. It works flawlessly and was inspected and approved by the local Electrical inspector. Very happy product.
