## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works just fine
  

*by M***N on Reviewed in the United States 🇺🇸 on May 11, 2023*

Had to shorten the piece that prevents the generator breaker from turning on. It was to long not allowing the breaker below it to  turn on. So. I shortened with a hacksaw. Otherwise it is just what I  expected.

### ⭐⭐⭐⭐⭐ 







  
  
    A safety Generator interlock is a MUST have for anyone installing a generator backup.
  

*by G***G on Reviewed in the United States 🇺🇸 on May 7, 2023*

Don’t risk feeling voltage back to the power grid, Install a Safety Interlock on your electrical panel. This fit my 50 years old Square D panel and keep the Generator Breaker locked Off.Natupal has many types to choose from.

### ⭐⭐⭐⭐⭐ 







  
  
    Very nice product, required a minor modification
  

*by A***R on Reviewed in the United States 🇺🇸 on March 16, 2023*

Nice product. I had to trim about a quarter inch off the bottom of the lower arm that interferes with the generator breaker as it was to long and contacted to breaker below it. My breaker panel DID match the required measurements but it is a very old Square D panel, 1960’s model so I wasn’t expecting to find anything compatible when I found this. Otherwise the item works perfectly. My new off grid solar inverter is now safe from being back fed from the grid.
