QO HM Breakers save my workshop

Thursday, April 07, 2011

I recently had a new service panel installed using standard QO breakers. The problem I was having was that each time my compressor or dust collector turned it would trip the breakers. The HM breakers came in this week and I installed them right away, they were just what I needed.

It works as expected

i am a happy camper right now
