Square D - QOCRBGK1C 100 Amp QO Load Center Outdoor Generator Inter-Lock Kit

Worked just like expected

I needed to add a little extra length to the interlock to ensure that both breakers could not be on at the same time. The little flange thing that rests on the lower breaker was too short and did not prevent the main breaker from being turned on. A quarter inch of heat shrink did the trick!

Came with a robust steel template to drill the three necessary holes. Installation was a breeze. This will allow me to run a generator into a 4 inverter stack for contingencies.

Stated seeing changes in my cycle in just a few weeks

Says its for QO 100amp panel, not quite a perfect fit...disappointed.

A little expensive for what is basically a few pieces of stamped metal and a sticker, but works as advertised.

Great quality

Does what it is supposed to and straight forward to install

You can only use this product for its intended purpose, to chose which power source is suppling electric to your load center, and to prevent sending your generator power to the power lines and endangering someones life.

A low grade headache to find the right one for my 100 amp box, but this was it and it fit perfectly. I grabbed it as soon as the price dropped, I don’t understand why these cost so much but they may save a lineman’s life!
