200 amp panel w/100 amp service
I currently have 100 amp service in an older home that relies nearly entirely on gas for utilities. 200 amp service would be overkill and I have no intention of relying on electric heat or any other large electric draws.
However, my older 100 amp service panel does not contain enough slots to have an adequate number of circuits in the house; the kitchen is on a single circuit, as is the entire downstairs, and I have to be very careful to avoid tripping breakers. I would like to begin rewiring these circuits (and getting rid of any K&T) but am at capacity with my current panel (ca. 1970's, 20 slot CH panel).
Before I start calling electricians, city inspector, or power department, I'd like to get an idea of what my options are.
Is it possible to protect a 200 amp, 40 slot panel at 100 amps, either through a fuse or a breaker? If so, is there any term for this or is this an unusual configuration?
If this is not possible, is there such thing as a 100 amp, 40 slot panel?
