Main Circuit Breaker Help! Can't find the brand!!

[urs4everafter]

My dad is about to install a 125A Square D (HomeLine) circuit breaker Load Center. The product number we have is HOMVPL2 and it includes the load center, main lugs, ground bar and some circuit breakers. The problem we're having is that it says on the box that the Main Circuit Breaker is not included but we can not find any place that sells the HomeLine 125 AMP main circuit breaker. The papers in the box do not tell us any part numbers so we have no idea what we're looking for. Does this thing even exist or can another brand or AMP size be substituted for it? Maybe the QO 125 AMP Main??

Go to an electrical supplier that specializes in Square D products. Take the panelbox with you. Ask for a Square D SQD QO2125 Circuit Breaker. See if it'll fit. If it don't, the jobber will help you find a main breaker that will.
