I have an existing mobile home slab fed by 100A breaker in the main and #2 cables. New building on it has a 30 amp sub panel. Can I safely feed the sub panel without changing the existing sub surface wire and breaker in the main. Changing breaker in main to 30 Amp won’t accept #2 and will have to pull 10 gauge.
Sun panel on existing 100A Circuit
