[TheForge] emergency generator

I have a 50 amp outlet at my meter base. That lets me plug things in to run
them when the power is on.
When the power is off, I flip the main at the meter which disconnects me
from the power company and plug the welder into the outlet which lets me
power up the house.
While it would be dangerous to the lineman if you connect to the grid, it
would most likely either stall the generator or burn it out from the load.
