The lamp-type ground detection circuit on the main electrical switchboard is indicating a ground. When safe to do so, what is the MOST effective and practical procedure for locating the distribution system ground?
A
one by one, open the individual branch circuit breakers on the suspected distribution panel until the ground detection lamps no longer indicate a ground
B
one by one, check circuit resistances with a megohmmeter connected between the suspected grounded line and the distribution panel framework
C
one by one, physically examine the suspected grounded circuit paths while looking for burned spots
D
one by one, check all circuits suspected of grounds for continuity
