How many amps does a 220 volt hot tub use?

Although 220V/50AMP circuits are the most common there are some models designed to run on 60-100 AMP circuits. Higher amperage circuits may be required if the hot tub or spa has multiple jets pumps or multiple heaters such as the case with dual zone swim/exercise spas which require 100 amps.

Then, what size breaker do I need for a 220v hot tub?

The spa must be hooked up to a dedicated 220-240 volt, 50-60 amp breaker and GFCI.

Also, do hot tubs run on 110 or 220? 220 volt Hot Tubs. All HotSpring 110 volt spas can be converted to 220 Volt. 110 Spas can run either the heater or the Jet pump, but not both at the same time. If you are in your spa running the jets for more than 30 minutes, you may experience some heat loss – especially on really cold days/evenings.

Additionally, how many amps does a hot tub use?

The most common voltage requirement is 240 volts and most will need a 50 amp circuit. Some hot tubs have load requirements of up to 60 amps and others require only 30 amps or 40 amps. When wiring a hot tub, it is extremely important to correctly size the circuit breaker for the required amperage.

What do I need to wire in a hot tub?

Hot tubs with mixed voltage components (such as 120V ozonator and 240V heater) require 4-wire systems. This means they require an electrical circuit providing (2) hot wires, (1) neutral, and (1) ground wire. Check the owner's manual. The two hot legs (black + red) provide 240 volts (120V +120V).
