I inspected a condominium town home (late 1980’s) yesterday and the panel did not have a main disconnect nor a grounding conductor coming off the neutral bar. Also the dryer circuit was protected by 40amp breaker but the wire was awg10.
I assume that the main disconnect and grounding conductor are in a separate utility space with the meter.
Would my assumption be correct? Is this a common arrangement for condos? If so how does bonding of hot and cold water pipes work in this case?
Is there some kind of exception to the rule for a dryer circuit that it can be overfused? I have seen this arrangement in a number of service panels lately.
Any advice is appreciated.
