Here's my suggestion just to get you started.
Plug into 15 AMP ok but
shut off electric water heater and don't try to use the Air Conditioner.
You can use lights and exhaust fans and watch TV and run the fridge.
Also no electric heaters or electric "fireplaces" except when the "flames" are on but the heat is off.
Keep your cord short and we recommend heavy duty 14 GA extension cord
if you have to use one. Old familiar orange 16 GA isn't really up to the task.
Enjoy and by all means
