New Circuit Questions
I need to add a new 220 volt 40 amp circuit and receptacle to my garage. My panel is listed as being max of 225 amps. I have check with Oncor (power distribution company here in Dallas), and I have 200 amp / 240 volt service. The main disconnect is a dual 60 amp breaker. It is outlined in the picture below. Does this mean I have 120 amp service? If so can I replace the 60 amp dual breaker with a 100 dual breaker to increase my service to 200 amps?
