32 & 40 AMP electrical requirements For a 32AMP hot tub, 6mm² 3-core SWA cable is needed and a 10mm² 3-core SWA cable is perfectly suitable for a 40AMP Hot Tub. An IP65 45AMP Rotary Isolator Switch is also recommended so that the hot tub can be isolated outdoors in an emergency or for service work.
Do all hot tubs require a neutral wire?
Hot tubs with mixed voltage components (such as 120V ozonator and 240V heater) require 4-wire systems. These consist of just 2 hot wires and a ground wire, without a neutral wire. Both 3-wire and 4-wire spas must be GFCI protected. A 4-wire hot tub must not be connected to a 3-wire service.
How many amps does a 220V hot tub draw?
How many amps does a 220 volt hot tub use? Although 220V / 50 amp circuits are most common, some models are designed to operate on 60-100 amp circuits. Higher amp circuits may be required if the spa or hot tub is equipped with multiple jet pumps or heaters, such as dual-zone swim/exercise spas that require 100 amps.
Where does the wiring go on a hot tub?

What kind of wire do you need for a hot tub breaker?
A 12-gauge cable is thicker and useful when you have a 20-amp breaker. It is recommended that at a minimum you should use a 12-gauge wire. For a 240-volt hot tub, a 10-gauge wire with a 30-amp breaker setup is ideal. For a 50-amp breaker, an 8-gauge wire setup would be recommended.
What’s the difference between wire gauge and hot tub wire?
There are often times when professional hot tub installers get confused about the gauge of wire to use for the hot tub so that it can provide optimum performance.

Do you need a licensed electrician to wire a hot tub?
The power that runs the hot tub must be given a dedicated circuit because of its electrical demands. No other appliances or electrical demands should share the power. If wiring on your own, make sure your specs are right. Again, if there is any doubt about how to wire the circuit responsible for the hot tub, use a licensed electrician.

You may opt to cut a hole in the spa’s toe kick for the conduit.
What should I do if my hot tub wiring is wrong?
