Am trying to add a 20 AMP breaker into an existing Square D

Customer Question

Am trying to add a 20 AMP breaker into an existing Square D panel. Panel is identified as Type 1 catalogue no. QOC30U and has a graphic of series G1 breakers. Problem is that I cannot find any reference to G1 breakers online and am swamped by literally hundreds of choices and options by dozens of companies. Local breakers at Lowes do not have same physical appearance. Do not want to pull unit apart (kill power) until I have correct breaker in hand. Fill me in.

Hi, I'm Mike and I'll be glad to assist you. Square D plug in breakers will be acceptable. Some modifications have been made but the available ones will fit and work fine
