Hot tub sub panel supplying 120 v circuit

[Stevenfyeager]

I have a 48 amp 240 volt hot tub to wire. (Nameplate says 40/48 amps) If I install a 60 amp sub panel, what about installing a 20 amp, 120v breaker for an outlet from that same panel? (For a 120v outlet). Thank you?

Should not be a problem if the panel is installed in accordance with requirements applicable to any other sub panel.

Be careful with the nameplate ratings on the tubs. Some haven't factored in the 125% for the motor. So if they say 40A and haven't figured in the 125% then you really need a 50A circuit. The 48A would actually need a 60A.

40 x 125% = 50
48 x 125% = 60

So you need to see the specs on the tub to see what they say. It all depends on the number of pumps & heaters and whether they run at the same time.

wag, but a nameplate of 40/48A is depending on how the dip switches on the board are set and if it is a 50 or 60A spa. Basically amounts to what pumps can be run at x speed with or without the heater or jet/air pump on. I dont see a problem running a 120V receptacle from a 15 or 20A breaker from a 60A spa subpanel provided it's a 4 wire feed. Usually there's a receptacle close enough to the spa and the disco is a 50A/60A GFCI breaker.

Keep in mind that you will need #4 Cu or equivalent Al for a 60A panel.
