Can breakers add up to more than main?
It is very common for the sum of the branch circuit breakers to add up to more than the main circuit breaker. The engineer that originally designed the building and electrical system understood that the loads were intermittent, and very unlikely to be maxed out at the same time.How many amps does a dryer use?
On average, a clothes dryer uses 1,500 to 5,000 watts (W) of electricity, depending on the model. Most clothes dryers use between 7.5 and 30 amps, and connect to a 240 volt outlet.Should I get a 200 or 400 amp panel?
“200-amp service will handle the same load as 100-amp service, plus electric appliances and electric heating/cooling equipment” (in a small to medium-sized home). “400-amp service is recommended for large homes with all-electric appliances and electric heating/cooling equipment.Can you run 220 on 100 amp service?

For that matter, if the main breaker were out at the meter (e.g. a meter-main), you could simply "tee" off it with dual 4/0 to two main-lug panels.What is the 80% breaker rule?
The 80% (standard-rated) breaker can only be applied continuously (defined as 3 hours or more by the NEC) at 80% of its continuous current rating (or Ir setting; e.g. if a 150 A H-frame is dialed to 100 A, the 80% rating applies to the 100 A setting).What is the 125 rule electrical?
For branch circuits, NEC 210.19 states the rules for sizing conductors. The general rule is that conductors are sized to have an ampacity of not less than the noncontinuous load plus 125 percent of the continuous load. The corresponding rule for overcurrent protection is given in NEC 210.20(A).Can 2 circuits share a neutral?
A shared neutral is a connection in which a plurality of circuits use the same neutral connection. This is also known as a common neutral, and the circuits and neutral together are sometimes referred to as an Edison circuit.
