This may be a bit off topic, however, I have just wired in an electric heater for my shop. The heater is a 208/240V @ 19.6 amps. The breaker that supplies my shop (detached) is a double pole 10A 10AWG 3+ground. Question is: If the main breaker from the panel is 10A, is that per voltage lead, or overall. If the heater requires almost 20A, then do I want a 220 single pole (double 20A with trip cap on top) or double 10A.
Any help appreciated
