The instructions were great. The only problem was the letters on the wires were hard to read.

Very Clean Set-up
By Eric Y.
San Clemente, California
Purchased 12/17/2021 |
Review Posted 01/11/2022
This is a quality product that will last. I was a bit thrown off by how it was to be wired in. The directions were not very descriptive. Having electrical experience, I was able to figure out the system and do it myself. Wires are labeled in very fine print so I took the time to tag each wire with my labeler so I could be sure each branch was wired in correctly. The conduit provided was just big enough to fit the 22 30” wires. I recommend anyone with an inkling of a doubt get an electrician to install this.

Works Like Advertised
By Mike Q.
FORT WORTH, Texas
Purchased 09/13/2021 |
Review Posted 10/14/2021
Took a little over 3 hours for my electrician to install. Worked immediately when activated. Looking forward to our first power outage with the new generator and this transfer box to power the items in our home that we decided to power during any outage. Came in less than 2 weeks when 4-6 weeks minimum was quoted.

Good QUALITY
By Alex M.

Purchased 07/15/2021 |
Review Posted 08/27/2021
Good quality well made feel solid, with one small exception the lock does not latch properly to lock the transfer switch but not big deal for me as never intended to lock, otherwise happy with my purpose. Two week after installing had opportunity to use and worked great.

I Always Use This Product For My Customers.
By Jeff W.
SEBASTOPOL, California
Purchased 07/14/2021 |
Review Posted 08/25/2021
Love this transfer switch and use it all the time for my customers. Couple things I would like to mention. The last shipment did not come with the keys to unit and the front plate has to be slightly bent at the top to fit in slot above breakers. The unit is equipped for 30amp two pole but only comes with two 20 amp breakers, no two pole 30 amp. Other than that I have no issues and will still give 5 stars across the board. Thanks

Great Fully Comprehensive Kit
By Douglas B.

Review Posted 08/24/2021
The unit prewiring was excellent with all wires clearly labeled. Length of wires was good and conduit piece good for an easy installation. The most difficult task of the project was selecting the circuits to balance the load between the two sides.
