Probably need a little clarification. Fuses are usually associated with 12VDC and circuit breakers are associated with shore power 120VAC. You should work on them one at a time. You can connect the TT to you home outlet, but if you have a GFCI protected home outlet you are plugging into try one that is not GFCI outlet. Also limit what you run in the TT unless you know what is running on that circuit in the house. You also need to check for a tripped GFCI outlet in the TT. There is almost always one someplace usually in bathroom or kitchen, but sometime outside.
