As is I am not concerned about a fire whatsoever. I will try replacing the 15amp breaker first, I don't have an amp probe. At this point I just want to get through Friday as I want to do a couple minor projects. A box in the garage sounds like the best way to go and I'll run it by the electrician.

Run heavier gauge wire for a couple of dedicated outlets or get a nice generator with a 30 amp circuit.

Well I unplugged the freezer because we barley use it anyways and changed the 15amp breaker with a new one. It seemed to be ok today but the real test will be when I get the air compressor, lift, bunch of lights going at the same time. Didn't need the air comp today. Then I'll revisit it again. But a sub panel would be the ticket for sure!

This is good advice.

The breaker is doing what it's supposed to - preventing a circuit overload. Don't override it.

If you need heat, LP or kerosene space heaters work great. There are ventless LP models out now with exceptional heating characteristics, over 99% efficient and little to no danger from fumes. There are ethanol heaters too with similar "no CO" benefit, but it's hard to get a lot of BTUs out of them.

Electric heat is also damn expensive - at least in this area...
