This may seem obvious, but should the total amperage of the circuit breakers be the same or less than the svc. in the panel, or can it be more? We are rewiring an old 3 story house which was originally on only 2 circuits. We have a new svc. panel w/100 amp which is sufficient as all major appliances are gas. BUT...we have many new circuits coming in from 3 stories and basement and garage...provided we check total amperage for entire house and individual circuits, is it possible to have, say, 3 20 amp circuits/circuitbreakers and 5 15 amp circuits/circuit breakers which total 140amps yet each circuit may have only 5 outlets or ceiling lights and so TOTAL house usage under the 100amps of service panel? Or am I limited to 2 20amps and 4 15 amps? If I were so limited, could I "pigtail" two small 20amp circuits under one circuit breaker?

You are OK.....The breakers themselves are for overloadig protection. Often time the total breaker value exceeds the Service. With everything on in the house, I mean everything, you may only draw 50-70 amps. The breakers make sure that a particular curcuit doesn't overload and burn the wire....

An answer was given?

Not very clear!

Any other comments on this old question and thread?

Well, here's a thought:

Three stories, a basement and a garage?

In such a large structure, why would anyone go to the expense of upgrading to a new panel of only 100 amps?

You may like gas appliances, but if you ever decide to sell the place prospective buyers may not -- and if they're at all savvy they'll be asking the same question.

Well for one thing, you should only install the amount of breakers in the service panel that the manufacture allows. For axample, you should not install more than 20 breakers in a 20 circuit panel. Even though twin breakers might fit, it would be against the manufacture's instructions. If the panel was a 16/24 service panel, that would mean that you can install 16 full size breakers, or 24 circuits using twin breakers. Also be careful that the twin breakers are only allowed in the correct spot as per manufacture's instructions. (Usually in the bottom slots.)
