If you have them it would not hurt to use them.
The control box should have its own fuse built in for the controller voltage.
It is just a bit strange for a 230V controller to have a 115v plug.
What do you plan to do with the Neutral. ? Does your generator have a GFCI ?
You only need to stand back 10 feet, That way you do not miss out on the smell.
Good Luck. Wear your PPE.
The box has a 20A single pole circuit breaker/overload protector for the primary power line. Nothing for the other hot leg because I guess it was made originally as a 110v controller with neutral, so no need but for a single overload.
They have the exact same pump for 110v with the same box and wire, but they sell the 220v pump with the same too. I kinda wondered how they were going to pull off the 110v version of this 2hp pump with 12ga wire, since the effective amperage would be doubled, but that's their problem.
I'm simply substituting the neutral wire routing in the box as the second power line. By process of elimination for the motor wiring, one brown being the capacitor start line, the other being the ground, the black and blue wires line up with the power and neutral on the 110v version, so I'm just substituting the additional 110v line with the neutral line in the box, theoretically converting to 220v control box. That's the only way I can see it and I hope I'm correct in my logic, or I will find out soon enough.
I plan on setting it all up in the morning some time and hope to have good news later.
