You have already made the best decision toward Every Day Made Better by incorporating a hot tub into your lifestyle. Provide an area to place the hot tub 2. Make sure the electrical is hook up. The electrical setup needs to be done by your electrician, as our delivery techs are not licensed to do wiring on anything other than the hot tub itself. The electrician will then wire the hot tub to the home.
This means that the feeder breaker in the house service panel must be of the specified size. It must be adjacent to the hot tub, at least 5 feet away, and within line of sight. Now let's take a look at a typical backyard installation. In our movie below, we've already poured a level cement slab and placed our Belize portable hot tub on it.
For a quick, easy, and lower cost alternative to concrete, check out Handi Spa Pads. Per the owner's manual, our hot tub requires a V, 50 amp 4-wire electrical hook-up, using AWG 6 copper wire. The electrician is running all buried wiring in 1" rigid Sch grey PVC electrical conduit. Refer to your owner's manual for wire requirements. Select the tabs below to follow the project from Planning through Hook-up:.
A large portion of V spas manufactured today require a 50 amp 4-wire electrical service. Some hot tubs have load requirements of 30A or 40A, and a few even 60A.
These requirements correspond to the size of the new feed circuit breaker installed in the house service panel. The Disconnect GFCI panel's amp rating can be equal to, or larger than the feed breaker in the main panel.
Hot tubs with mixed voltage components such as V ozonator and V 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. One hot leg with the neutral white wire provides V. The ground wire green carries no current except when a short circuit to ground occurs.

This causes the circuit breaker to trip on overload not to be confused with the safety function of the GFCI. Many older V spas and some newer ones use 3-wire installations.
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. Proper grounding is also essential. In either case, the disconnect panel must be supplied with 4-wire service in order for the GFCI to function correctly.
Refer to the spa owner's manual for wire gauge, etc.
Dedicated Electrical Circuit Breaker: The electrical service to the spa must include a suitably rated switch or circuit breaker. Whether the spa is a V/60Hz Cord-Connected spa or a V/60Hz, V/60Hz or V/50Hz Permanently-Connected spa, it is required that the circuit breaker that supplies power to the spa is dedicated and does not.
The interactive schematic diagram below shows 3 and 4 wire configurations. Select the wiring configuration that your spa requires:. Size the feeder circuit breaker in the service panel according to the spa's load requirement. You can find this information in the owner's manual, or an electrician can determine the value for you.
The load rating of the disconnect box should be greater than or equal to the breaker in the house service-panel. The electrician can easily determine if your electric panel can accommodate the new V circuit required for this project.
There also must be two available slots in the box for a double-pole breaker. In most homes, this will not be a problem. When selecting an electrician, be sure to ask about experience installing hot tubs, particularly 4-wire configurations.
Per the owner's manual, our hot tub requires a V, 50 amp 4-wire electrical hook-up, using AWG #6 copper wire. The electrician is running all buried wiring in 1" rigid Sch grey PVC electrical conduit.

Jacuzzi, spa or hot tub electrical installation? You can get a free consult with our in-office electrician in Mesa AZ. If your hot tub's electrical hook up requires a connection to your main service panel and it is clear on the other side of your home, utilizing your attic as a method of wiring can. Hot Tub Electrical Setup You have already made the best decision toward Every Day Made Better by incorporating a hot tub into your lifestyle. Before it's delivered you really only have to do 2 simple steps: 1.) Provide an area to place the hot tub 2.) Make sure the electrical is hook up.
The most common wiring mistake occurs with 4-wire systems. Unfortunately, we've found that even a few professional electricians fail on this one. Attach the white neutral wire to the spa's control box directly to the neutral terminal of the GFCI breaker. See our 4-wire diagrams above. Do not attach it to the sub-panel grounding bar. Miswiring it to ground instantly trips the GFCI when energized, cutting power to the hot tub. We prefer the protection of buried conduit in a backyard setting where future digging may occur for planting scrubs, etc.
PVC pipe is easy to install and inexpensive. Secure conduit to walls with U clamps. In our example, 4 wires are used in 1" PVC conduit, which although a bit oversized, makes pulling the wire easier.
Threaded PVC terminal adapters are cemented to the conduit for electrical box connections. Our electrician used short lengths of flexible liquid-tight PVC conduit for the connections to our spa control pack.
From the outside wall through to the electrical service panel, he ran LB Condulet. The LB allows easy access for running the wires. Where local code requires, use PVC expansion-joints where conduit pipe emerges from the ground, enters a wall or wall-mounted enclosures. These slip couplings allow for changes in grade usually associated with frost heaves, to help prevent breaking of the conduit.
PVC electrical conduit should be assembled prior to running wire. It is generally easier to fish wires through conduit in the trench before it is buried. Cuts should be made square, using a cutting tool or PVC wire-rope saw.
Remove burrs with a utility knife and medium-grit sandpaper. Dry-fit pieces before gluing. Joint surfaces should be wiped clean before joining. After reviewing the spa owner's manual, our electrician determined that our project needed 6 THHN stranded copper wire.
Your wire gauge requirements may differ from our example, depending upon the spa manufacturer's specification, code requirements, and wire type.
Unusually long runs may require larger wire size, as determined by the electrician. Although copper is not cheap, scrimping by using under-size wire is a hazardous false economy.

Aluminum or copper-clad aluminum wire is not recommended. Sheathed cable, i. Note: Spa control box terminals generally cannot accommodate wire larger than 6. Refer to the owner's manual.
How to Wire a Spa - Wiring for V and V hot tubs
Some localities may allow direct burial cable, at least for the run from the service panel to the disconnect box. Other jurisdictions prohibit it.
UF-B cable can be cumbersome to work with, according to some electricians. With proper preparations, pulling wire is not terribly difficult.
After conduit is assembled, electricians use a narrow spring steel fish tape to route wires through it.
The first few inches of the tape are coated with wire pulling lubricant. This helps it slide smoothly over fitting edges and around bends of the empty conduit. First, the tape is snaked through the empty pipe, being careful not to kink it by jamming.
Then the wires are attached to the hook on its end, and pulled back out. Carefully push the wires into the conduit, keeping them separated and straight, avoiding kinks.

Apply lubricant to the wires as they enter the conduit. A second person pulls from the opposite end with the fish tape tool. A common mistake is to wrap all of the wires to the hook of the tape.

While a backyard spa is a great way to relax and have fun, the installation involves specific electrical requirements. For most full-sized spas, the National Electrical Code (NEC) requires: Hard-wiring the spa into a ground fault circuit interrupter (GFCI)-protected V or amp dedicated circuit. Apr 25, Assemble the hot tub and hook up the electricity. The voltage of a hot tub is higher (usually around volts) than regular home outlets, so you will need to install a breaker to your electrical control box.
