The size of the wires, however, will be the same as aluminum wires, 2 or 3 AWG. Is 150 amp service enough? NOW with that said - I often use those push button circuit breakers for when i need an FUSE and ON/OFF switch capability ... The best size of wire for 150 amp is 1 AWG copper or 2 AWG aluminum or copper-clad aluminum. If the temperature is around 194°F, use a 3 AWG aluminum wire gauge.

The old houses used to have 30-60 amp electrical services, which was enough at that time because there wasn’t as much electrical equipment as today.
