Hm. Found a number -- it appears that a standard circuit breaker is 15
amps (1650W). That's what you can draw from an ordinary plug in a home
without blowing the circuit breaker.
A typical home might be capable of a total of 100A, however (11,000W).
That's what you could draw from the line leading in from the street.
Larger buildings will be capable of several times that.
Power substations vary quite a bit, from a few tens of kilowatts up to a
couple megawatts for large area substations in europe; typical electric
power requirements are on the order of a kilowatt per person for a city, I
believe.
To add to the confusion:
Residential AC 2.5 - 6 kw, usually a 40 or 60 amp breaker, 240v, 3 phase,
60 hertz
Clothes dryer 4 - 6 kw, usually 30 or 40 amp, 240 v, 3 phase
Kitchen appliances 1 - 2 kw, 20 amp circuit breaker, 120 v, single phase
Range (all burners & oven on) 8 - 14 kw, 240v
Most houses are a 100 amp panel with a 20% safety factor so can pull 80
amps. I vaguely remember a mid sized house being around 60 amps.
Burger King 600 amp panel, Red Robin Restaurant 800 amp panel (same
20%), strip center & mall retail spaces are 100 - 200 amp.
