What is needed to wire a hot tub?
Hard-wiring the spa into a ground fault circuit interrupter (GFCI)-protected 220 to 240V, 50 or 60 amp dedicated circuit….The electrical tools you will need to wire a hot tub are:
- Voltage tester.
- Set of screwdrivers.
- Wire stripers.
- Side cutters.
- Drill.
- Hole saw kit.
- Fish tape.
- Electrical tape.
What wire is needed for a hot tub?
size 6 AWG copper wire
Avoid using aluminum for hot tub wiring. Instead, use size 6 AWG copper wire with THHN (thermoplastic nylon) insulation. Use fish tape to pull the wires through the conduit from the fitting to the spa panel. As you pull the wires through the conduit, leave 6 inches of extra wire hanging from all ends.
What power supply is needed for a hot tub?
How many amps do you need for a hot tub? Most hot tubs require at least a 13AMP supply with larger hot tubs requiring a 32AMP supply.

Can I wire my own hot tub?
As with all electrical projects, follow local codes and consult an electrician before wiring a hot tub. The National Electrical Code (NEC) requires: Hard-wiring the spa into a ground fault circuit interrupter (GFCI)-protected 220 to 240V, 50 or 60 amp dedicated circuit.
What wiring is needed for 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).
Does a spa need a neutral wire?
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.
Why does 220v have 4 wires?
The reason this change was mandated by the National Electrical Code is that the 4-wire setup is inherently safer and better able to prevent electrical shock, which in the case of a 220/240-volt circuit can be fatal.
