I think I'm on the right track, but I want to ask folks before doing something messed up or potentially killing others or myself.
So I finally broke down and got a nice brand new generator at a very good price it's a 9kw portable genset. I plan on using it to power my 1/2HP (240v) well pump, my forced air gas furnace (120v), and a few LED lights when the power goes out.
On my house, I have an outdoor 6-50P receptacle for my welder which is directly fed to my main breaker panel for the entire house. Right next to the 6-50P receptacle is the grid's meter, and of course the grounding rod for the house.
My welder breaker happened to be right below the main circuit breaker for the whole house, so I installed an interlock with a LOTO. This way I can't inadvertently back feed into the grid and potentially kill a grid worker or some one else.
My only other question is the wiring of the genset. On the genset I got the usual L14-30P receptacle. The genset's neutral is bonded to the frame of the genset according to the manual and the front of the genset. It tells you to ground the genset frame.
I bought the materials to make a 6-50 to L14-30 adapter. I wired it up as follows:
6-50=L14-30
G=G
HOT=X
HOT=Y
empty=N
I plan on using a 6ga wire and ground the frame of the genset to the existing house grounding rod right below the meter and next to the 6-50P receptacle where I intend to temporarily run the genset.
I know this isn't OSHA or NEC approved, and this isn't a permanent installation. It is strictly for those situations when I absolutely need water, heat, and a few lights.
Main concerns:
1. I don't want to jeopardize the safety of a grid worker.
2. I don't want to touch metal casework in the house and get a nice jolt or die.
3. I don't want to touch the genset and get a nice jolt or die.
This is why I am asking before I just "do".
