So my friend had an ex install a subpanel out on a separated deck for a hot tub. They couldn't get the hot tub main board to power on. I come over one day and found the following:
•Subpanel has 2 hot legs and a ground coming in.
•Using 60amp GFCI 220v breaker
•Load Neutral coming from the circuit breaker was connected to Neutral bus bar
•Neutral from hot tub was connected to Neutral bar
•Jumper was placed from Neutral bar to Ground bar..............
Measuring each hot to neutral gave 120v, measuring to ground gave 120v, but measuring hot to hot resulted in 0v
Detached jumper from ground to neutral.
Same measurings to ground but to neutral was no 0v.
Replaced circuit breaker
No change
I ran a wire from the subpanel back to the main panel at the house but inside the panel the neutral and grounding had a jumper bar across that aswell...
Is there something I'm missing or is it time to throw in the towel?
