A: Hi Maip, Yes, this Square D handle tie will work on your Square D QO breaker. Joseph
A: This handle tie is for a thin (THQP series) GE breaker. You need to find one made by Square D for your Square D breaker.
A: Hello Dave and thank you for your question. This is George From our How-To-Community. Dave this tie is designed to work with GE slim line of Q line breakers. If i recall correctly distance in between two THQP breakers its more like 1/2". Hope this helps.
