Can an electrical panel that was once used for a Sub-panel be re-used as a main house panel?
There was no main disconnect above the breakers and the sparky installed a 100-amp breaker on the side near the top on the right side of the breaker spaces. This 100-amp breaker receives the service entrance wires, so when you flip the 100-amp breaker, the panel should not be energized? He has all the other breakers neutrals on the the grounding lug and the old sub panel has an additional grounding bar added inside the panel. There is a ground rod and water-pipe ground on this set-up as well.
I have never seen this set-up before and can only find information on making a main panel into a sub-panel, not the other way around.
Is this a poor mans way, using an used panel?
