Hot tubs with mixed voltage components (such as 120V ozonator and 240V heater) require 4-wire systems. The Disconnect GFCI panel's amp rating can be equal to, or larger than the feed breaker in the main panel. These requirements correspond to the size of the new feed circuit breaker installed in the house service panel.
Some hot tubs have load requirements of 30A or 40A, and a few even 60A. Select the tabs below to follow the project from Planning through Hook-up:Ī large portion of 240V spas manufactured today require a 50 amp 4-wire electrical service. Refer to your owner's manual for wire requirements.
The electrician is running all buried wiring in 1" rigid Sch-40 grey PVC electrical conduit. Per the owner's manual, our hot tub requires a 240V, 50 amp 4-wire electrical hook-up, using AWG #6 copper wire.

In our movie below, we've already poured a level cement slab and placed our hot tub on it. Now let's take a look at a typical backyard installation. The NEC also requires a 120V receptacle within a 10-20 foot distance from the spa. It must be adjacent to the hot tub, at least 5 feet away, and within line of sight. *The National Electrical Code (NEC) specifies installation of an approved manual disconnect device. MW Spa GFCI Load Center/Disconnect Panel for Hot Tubs up to 50A with bonus 120V Branch Circuit Expandability The three electrical assemblies involved in this project are the: We're using a typical outdoor portable home spa installation for our example. Additionally, the GFCI breaker in the disconnect panel must be at least that size, and GFCI protected for safety. This means that the feeder breaker (in the house service panel) must be of the specified size. A 240V spa must be supplied by a circuit which meets its load requirements (amperage) as indicated in owner's manual. We'll begin with an overview of the electrical requirements for wiring a spa, illustrated by our interactive wiring diagrams.
This is false - capacity is determined by load calculations, not the size or number of its breakers. It's commonly misunderstood that the total amps of all installed circuit-breakers must not exceed the service panel's indicated amp rating. Panel ratings are normally labeled near the main breaker at the top. It's usually not a problem, since most homes built in the last 30-40 years have at least 100 amp service. Improper wiring may damage equipment and void the spa manufacturer's warranty.īefore installing a major appliance like a hot tub, determine if the electric service will handle the extra load. Shut off electrical power to the hot tub or pool at the service panel prior to any inspections or work.
#220 VOLT PLUG WIRING DIAGRAM MANUALS#
The installer should read and follow the hot tub owner's manual and associated electrical component owner's manuals and instructions. The local code regulations must be followed, with permits and inspections obtained. Local code requirements for wiring vary and may differ from the educational examples on this web site. We strongly advise that hot tub electrical wiring be referred to a licensed electrician. There is a risk of shock or electrocution, which could result in serious injury or death. We'll walk you through a typical project to show what's involved.ĬAUTION: Electrical work and repairs can be dangerous, especially around water. If you're not confident or qualified to do electric wiring, there's still installation prep-work you can do to reduce expenses.
