2) What is the approximate distance from the main electrical panel to the detached building?
3) If installing a sub-panel, how many amps will the feeder circuit be? 20 amps?
4) Does the underground wires contain an equipment grounding conductor? How many wires in the underground? 3 or 4 wires or are the wires installed in Rigid metal conduit?
Thanks for the replies.
1) Will the 20 amp breaker be installed inside the locked building or in the garage? Does the locked building contain a sub-panel and this is a separate building from the garage?
