The best way to determine this is by the size of your service entrance
conductors. These are the underground or overhead wires that feed your
house, but not the conductors from the utility company, which are often
smaller. These are usually aluminum and standard sizes a 4/0 = 200 amp,
2/0= 150 amp, #2= 100 amp. The main circuit breaker will determine this,
ONLY if there is a single main breaker

How can one tell the number of amps entering one's home at the main
service entrance? In doing a Google I've run across phrases like "100
amp service" and "200 amp service" and of a homeowner's 100 amp
service being "maxed out". Is there a standard number?
