Hot Tub Power Supply: What Prescott Homeowners Should Know Before Plugging In

The weather in Prescott is warming up, and more homeowners are ready to enjoy their new hot tubs in the backyard.

We understand that hot tubs are big purchases. But many overlook the most critical part—the hot tub power supply.

“A lot of times, I understand a homeowner has just made a big purchase on getting a hot tub,” says Jeff Brandlin.

“But they’ll skimp on the power supply.”

Cutting corners on your electrical setup can lead to safety issues and poor hot tub performance. Let’s break down why it matters.

Why a Proper Hot Tub Power Supply Isn’t Optional

Hot tubs use electricity to run their heaters, pumps, and jets, which quickly adds up to a serious power demand.

If your hot tub power supply is too small, the system could overheat, trip breakers, or even create a fire hazard.

“It’s very important to have the GFCI protection in place to protect the occupants in the hot tub,” Jeff Bradlin – AES Founder explains.

A GFCI (Ground Fault Circuit Interrupter) cuts off power immediately if it senses any irregular current in the electrical flow.

That fast response helps prevent electric shock—especially important when water and electricity are involved.

Hot Tub Power Supply Options: 120V vs. 240V

Some models work on 120V and plug into a regular outlet. This is often called a plug-and-play hot tub.

However, 120V systems have serious performance limits. Most cannot run the jets and heater simultaneously.

“They don’t have the full functionality that you would get by running the larger GFCI protected circuit,” Jeff says.

That means your hot tub may lose heat while the jets are on. You’ll feel it more on cold Prescott nights.

Why a 240V Hot Tub Power Supply Works Best

A 240V system requires a dedicated electrical circuit and a hardwired connection, usually installed by a licensed electrician.

But with 240V, your hot tub runs better and maintains temperature while the jets are on—no more cold soaks in winter.

“You have more comfort,” Jeff adds. “And more safety being GFCI protected.”

This setup also meets national code requirements and is safer for your home and everyone using the hot tub.

Signs of a Bad Hot Tub Power Supply Setup

We’ve seen installations with undersized wires, no GFCI breakers, loose connections, or junction boxes buried underground.

Those setups might work at first, but they wear out fast and put your safety at risk when you least expect it.

Only a licensed electrician can ensure that your hot tub meets the code and performs as it should in the long term.

That includes checking breaker sizes, wire gauges, conduit placement, and ensuring everything is properly grounded.
