I currently have a square D HomeLine 100 amp, 20 space, circuit breaker load center with one 60amp sub panel. I am upgrading as much of my house’s wiring as possible and fixing 45 years of creative wiring.
In the middle of my yard I have an outside main fuse block with two 100amp cartridge fuses in the block. I assume this means I have a 100 amp feed to the house. The wire to my fuse box is #2 seven strand copper and about 110 feet from the fuse block in the yard to my inside load center.
I would like to replace my main breaker box with one that has as many spaces and amps as possible (within code for New Mexico) to allow for adding a 48 amp kiln and other items and general flexibility in the future without having to rip out the box again. How big can I go?
