## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to install,  works great.
*by A***D on April 4, 2025*

Inexpensive and easy to install to ensure that the main utility breaker that feeds your panel cannot be on while the breaker to your generator is on. Comes with various safety and warning stickers that you can use in your panel. I found it easy to install and it works great. There's no way both breakers can be on at the same time

### ⭐⭐⭐⭐⭐ Requires Thoughtful Installation
*by S***O on December 17, 2024*

Clever device to positively isolate generator from utility power during operation. Should be installed by qualified electrician. Needs 1 open 2-pole space for generator breaker (not supplied). Main breaker must be turned off for proper installation. Includes clear instructions and labels for operation after installation. Can be installed when Main Breaker is at the bottom of the panel - like mine is. Good economical alternative to a transfer switch.

### ⭐⭐⭐⭐⭐ Worked well except for an additional internal interlock
*by L***L on October 4, 2024*

This seemed to be a quality kit and it was easy to install; the template was correct for my Square-D QO box. My kit came with an additional piece that was supposed to install inside the box, behind the panel, to hold down the critical breaker, but that piece did not fit. That was Ok, as I don't see the need for it anyway! And it looks like the kit now no longer includes that piece anyway!
