I recently rode along on an inspection of a townhouse.
The service panel was 100 amp,it was a full panel about 20 breakers.
Three breakers down on the left side of the panel was a 100 amp
double pull breaker to a sub panel in the basement. The basement
sub panel was full about 20 breakers. We couldn’t take the front
off the upstairs panel it was framed into the wall.
My question is this 100 amp service panel overloaded what
exactly were we looking at? I know most sub panels are feed
with 30 amp feeder if the service panel has capacity.
It seems if you figured volts divided into watts this system
it would be over 100 amps.The townhouse had an elevator.
What were we seeing here? Has anyone else seen this situation?
