Zinsco Breaker for 220v Hot Tub

So I'm not sure which kind of breaker I need for my hot tub. I know my box is a 2 pole Zinsco and my hut tub calls for a 40 amp 240v. Can anyone help me out? Thanks

From the information you provided, you would need a 40 amp 2-pole Zinsco breaker to feed a NEMA 3R spa disconnect panel with a 40 amp GFCI breaker, assuming the hot tub is outside. I would strongly recommend you change the main panel first, Zinsco panels are known fire hazards.

Home Depot carries "Hot Tub" GFCI protected breakers. At least they do in the stores near me. Make sure you use the correct gauge wire.

No such thing. What did you mean? Did you mean a Spa panel as suggested by Joe or individual breaker? If breaker it must be rated for the panel it is used in. I doubt a Zinsco GFCI breaker exists because the company went out of business before GFCI breakers were available.

I have seen both 50 and 60 amp spa panels with GFCI breakers in the box stores, but never one with a 40 amp GFCI breaker. I believe a 40 GFCI breaker would have to be ordered through a supply house/distributor.

The main Zinsco panel still needs to be changed.
