I've wired a cutler hammer 50 amp hot tub circuit, attached the leads(220v) and ground and neutral to correct terminals. As soon as I turn the breaker trips off. the hot tub is new, the box is new, wiring all new, UI have either wired it incorrectly or something is amiss in the tub. Adivce would be greatly appreciated.

Thank you in advance,

Don

One thing to note, and it happens all the time...

Please read the following carefully....

The 50 amp GFCI breaker will have (4) wires hooked up directly to it.

If the neutral from the spa control box is hooked up to the neutral bar in the subpanel, the breaker will trip instantly.

The GFCI breaker has a permantly attached pigtail, as well as 3 additional terminals (two hot and neutral) for a total of (4) wires

When incorrectly wired, (most commonly) both hot leads on the breaker are wired properly, the permantly attached pigtail is wired to the neutral bar, and the neutral terminal on the breaker is left blank. The neutral from the spa is incorrectly wired to the Neutral bar in the subpanel instead of the neutral terminal on the GFCI breaker.

To remedy that proble, simply remove that neutral from the neutral terminal bar, and attach it to the neutral terminal on the GFCI breaker

Good luck!
