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.Both 3-wire and 4-wire spas must be GFCI protected.
What are the electrical requirements for a hot tub?
What are the Electrical Requirements for hot tub installation? Hot tubs either require 110V or 220V of electricity. If you choose a 110V model often referred to as plug-and-playthen you may be able to simply plug the spa into an electrical outlet in the backyard.

Does a 240-volt circuit need a neutral?
The way you get a 240-volt circuit is simple. A double-pole circuit breaker is clipped into both 120 buses at the same time, so the voltage to the circuit is doubled. That’s why 240-volt circuits need two hot wires and a neutral to carry the electricity to the appliance, plus a ground wire.
Can you use a GFCI breaker without a neutral?
On 2P 15A to 50A the GFI breaker will work with or without a load neutral wire. However, if there is no load neutral wire the breaker neutral (white curly wire) must still be connected to the panel neutral.

Are hot tubs earthed?

What kind of wire do you use for a hot tub?
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.
Can I plug my hot tub into an extension cord?
Never use an extension cord for your hot tub. The cord provided with your spa is the proper length and gauge for current to travel safely from the electrical outlet to your spa. An extension cord forces the current to travel a longer distance and may result in a voltage drop or the cord overheating.
Can a plug and play hot tub be plugged into an extension cord?
Many inflatable hot tub manufacturers recommend against using an extension lead. This is likely to be for a number of reasons: Most DIY store extension leads use cable which is not sufficiently large in diameter (normally 1mmsq or 1.25mmsq) to handle the relatively high sustained current required. Most are rather long.
