What Size Wire Do I Need For A 240 Volt Hot Tub

A lot of spas today need a 50 amp 4-wire electrical service. If you are installing a new electrical system in your home, you will need to determine the maximum current draw of your new system.

You can do this by measuring the current drawn when the system is turned on and off, or by looking at the voltage drop across the load. If you do not have access to a voltmeter, it is a good idea to use a multimeter to measure your loads voltage.

This will give you an idea of how much current is being drawn by your system at any given time.

For example, if you have a load that draws 20A at full load, then you can use the following formula to calculate the amount of current that will be drawn during the first hour of operation: / = 1,000 Amps.

What Kind Of Wire Do I Need For A 50 Amp Hot Tub

The wire you need for a 50 amp hot tub will depend on the amperage of the breaker that is supplying power to the hot tub.

If the breaker is 20 amps, you would need 12-gauge wire.

If the breaker is 30 amps, you would need a 10-gauge wire. And if the breaker is 50 amps, you would need an 8-gauge wire.

How Far Can You Run A 50 Amp Wire

You can run a 50 amp wire or number six at least 100 feet without any voltage drop or any type of problems. Anything more than that then you should go to a larger size conductor a number for something ready for 80 amps. Once you go over 100 feet any large loads will have some sort of a voltage drop.

Now, there is a voltage drop calculation formula however we will not get into that. Just know that 100 feet is a good length to go with his rule of thumb. If you get too much voltage drop to your hot tub this will cause sensitive power issues inside the hot tub and could void your warranty.

You May Need A Gfci Breaker For Your Hot Tub

Youll find many homeowners asking for the correct wiring of, lets say, a 50 amp GFCI breaker for a hot tub. GFCI protection is a fairly common requirement for hot tubs. This is also usually dictated by where youll be placing your tub, whether its indoor or outdoor.

For outdoor hot tubs, youll need to pay attention to these requirements:

• The receptacle should be GFCI-protected and weatherproof.
• Its distance from the interior walls of the hot tub should be at least 6 feet and should not exceed 10 feet.
• You can connect the tub with a plug and cord, but its receptacle should be verified to be GFCI-protected. The wire run shouldnt be longer than 15 feet as well.

As for indoor tubs, you may be asked to adhere to the following guidelines:

• You must ensure that youre using a GFCI-protected receptacle.
• The said receptacles distance from the hot tubs interior wall should not go below 6 feet and above 10 feet.

If you are confused about the difference between GFCI circuit Breaker and GFCI receptacle, please check this article for more details.

On the whole, GFCI may be more expensive, but I think theyre well worth it for the peace of mind they impart, especially when dealing with possible ground faults.

Hot Tub Wire Size 50 Amp Aluminum Wire

Number 6 AWG aluminum wire can be used to wire a hot tub. Number six aluminum wire is rated for 55 A. So providing that it is used or on a breaker with overcurrent protection and 50 amps you can. There is one stipulation though.

Using an aluminum conductor to where your hot tub may void your warranty. You should check your manufacturer specifications on the hot tub to ensure that it doesnt request copper only. However there is a way around this.

You can run number six aluminum from your panel source to your hot tub spa buddy. A hot tub spa body is known as a small panel that is mounted on the exterior of your house. The spa buddy usually has a GFCI protection in it. From that spa buddy you can then run a piece of copper number six to the hot tub connections self.

Technically that makes the hot tub fed with copper. This is kind of a loophole in a way around it but we do it all the time its technically a hot tub is still fed with copper. This is good for installations when you have a really long run from your panel to your spa area. You can save you money to buy the aluminum over copper is aluminum is my cheaper.

Wire Size & Type For Hot Tubs

After reviewing the spa owner’s manual, our electrician determined that our project needed #6 THHN stranded copper wire. He used four individual insulated conductors: red & black-hot, white-neutral, and green-ground wire in our example.

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. It may violate code requirements and/or void your equipment manufacturer’s warranty. Aluminum or copper-clad aluminum wire is not recommended. Sheathed cable, i.e. Romex®, is not permitted inside underground conduit.

Note: Spa control box terminals generally cannot accommodate wire larger than #6. Refer to the owner’s manual.

Why Its Best To Follow The Manufacturers Recommendations And Guidelines

While I mentioned that the average hot tub breaker size is 50 amps, its almost always better to simply listen to what the spa brand recommends. They know their products best, after all. Dont be surprised if they ask you to use a higher 50 amp or 60 amp breaker.

For example, youll see tub specs stating its 40 amps but recommends a higher 50 amp circuit. Others are 48 amps, which bumps the requirements to a 60 amp breaker. Why is this the case?

Well, its more than likely that the manufacturer is anticipating other features of the tub. For instance, you may have a 48 amp tub with a heater that may do fine on a 50 amp breaker with just the pump running. But once you start the heater along with it, the circuit breaker trips.

In short, it mainly depends on how much youre utilizing a piece of equipment. Why would you opt for lower amperages knowing you wont make the most out of your spa if you do so?

The Requirements Stem from the 125% Motor Load Rule, Too

In the US, its often required to account for an extra 125% load for most motors. We arrived at 50 amps for a 40 amp tub because of the following formula: 40 x 125% = 50. The same applies to the 48 amp one.

120 Volt versus 240 Volt

Most full-size hot tubs are designed for 240 Volt electrical service. These hot tub wiring systems require a 40 to 60 Amp breaker and must be specially hardwired by a licensed electrician. Some smaller hot tubs, usually with only one pump and fewer jets, include a factory installed cord which incorporates a 120-volt ground fault circuit interrupter . This enables you to essentially plug them into a dedicated standard outlet. Referred to as plug and play, these models can also be converted to a 240V electrical service in the future, if desired.

About 120 Volt Connections

While plug and play hot tubs offer Day One convenience, they often lack in features. 120V spa units are usually only available with one pump. Additionally, heat up and recovery time may take longer with 120V hot tubs. Hot tubs operating on 120V service cannot have the pump operate on high speed while heating, so until high speed pump operation stops, the heater will not turn on. When connecting your hot tub via a standard outlet, dont share the circuit with another appliance, and be sure it has an appropriate amperage rating. Confirm your electric service can handle the load. 120 Volt myhottub.com spas are equipped with a 15-foot cord and a built-in GFCI. Warning: use of an extension cord will void the warranty and may damage your myhottub.com hot tub. Plan to place your tub within range of an outlet without the need of an extension.
