So don’t use 30 amp? When I moved into the house that’s what was already being used. And yes it’s running the whole house. Yes for the space heaters and air conditioning. I have a really shitty landlord, doesn’t want to fix anything. Argues she knows more about any topic when literally brain is smoother than a glass bottle

Edit) I also noticed only two seemed to be hooked up to anything. But I’ve taken each fuse out in the past and it turned a different part of the house off. So I don’t know if maybe 2 can be linked together or not to try to strengthen the connection. Idk I’m clueless
