I was at my friends helping him wire up a hot tub he recently acquired. I pulled a bonehead move and accidently switched the neutral and one hot leg coming off the GFI breaker. I turned the power on (nothing happened except a slight click noise), I tripped the GFI to see if it worked, which it did, then I turned it back on and checked voltage at the hot tub panel. Thats when I noticed I was only getting 120 between each phase, so I shut off the power and found my problem of crossed wires. I set them right, turned the power back on and checked voltage, which was now right, however nothing else seemed to be working. BUT, this is an old hot tub, very beat up (lights broken, side missing panels), plus there was no water in it yet. I'm no hot tub expert and have no idea if it's in working order, but if it isn't, I want to know if crossing the wires would have caused any problems? Like I said, nothing happened - no bangs, flashes, or even the smell of electronics frying.
