Photo https://ibb.co/Nj0nBFp https://ibb.co/P62Q1jN So I'm re wiringrewiring my 1957 house because there was no ground. I I have a main panel and a subpanel in the crawlspace that currently only give power to the gas furnace. I want to add the air conditioner on the subpanel (30amp breaker),a a 20 amp breaker for microwave and some outlets in kitchen, a 15amp for furnace, and a 20 amp for my bathrooms outlets.
Can I keep aluminium wire feeder ? What size breaker at the main panel ? I understand I need a ground kit for my subpanel, can I install it anywhere in the panel ? Thank you.
