Buyers guide to Hot Tub GFCIs

Review of Best Hot Tub GFCIElectrical safety should be the top priority for any place, whether it’s your home or office. In order to achieve electrical safety, you must always use the (GFCI) or the RCD. It is basically a circuit breaker that aims to greatly reduce the chances or risk of electrical shock.

It is an innovative device that helps prevent any electrical mishap. It breaks the circuit or turns it off once it detects that the current through the breaker is not passing in a way it should or if the current is being conducted through any third-party conductor such as a human body or water.

In some cases, it may also be helpful in preventing fires. These fires may erupt due to live wire or a naked wire touching the electrical conduit. Or a fire due to a short circuit may also be prevented.

Over the years various research has gone into HOT TUB GFCIs and they have improved the electrical safety of the  and home.

Here we discuss some of the best HOT TUB GFCIs out there on the market.


Important NOTE:

We HIGHLY recommend you consult with your local Electrician. They go through a rigorous apprenticeship and take a state exam to become license for electrical work. They will know how to safely install these types of breakers. Also the will be familiar with local codes and regulations.

Buying Guide

For some of you, the idea of going out and buying the best kind of HOT TUB GFCI may be a cumbersome and feared task. So to ease your work, we have compiled a buying guide on HOT TUB GFCIs for you.

Amp Rating

All circuit breakers have a rating on them called the Amp Rating, which basically defines the amount of current that can pass through the GFCI without it breaking. It is generally advisable for you to calculate the amount of current flowing through your circuit in order to determine the Amp Rating of the GFCI which you will need.

Not all GFCIs can work at the Amp Rating of your circuit. A GFCI should be able to handle at least 80% of the Amp Rating on it. Therefore, it is advisable to calculate the Amp Rating prior to purchasing the GFCI itself.


Number of poles

The number of poles determines what the quality of the GFCI will be and what kind of security and protection the spa circuit breaker will provide the user overall. There are three kinds of ground fault circuit interrupters at the moment. The 1-pole circuit breaker usually consists of a single tripwire which breaks the circuit once the anomalous current passes through it. These are not very reliable and tend to break easily.

The second kind is the 2-pole breakers which comprise of 2 wires being used in the GFCI. One is used for the neutral and one is used for the phase current. It is generally reliable to use the 2-pole GFCI in order to ensure maximum reliability and security. The 3-pole GFCIs use 3 wires instead of 2 or 1. They are obviously much more reliable in terms of tripping and security.


Mounting Style

There are basically 2 types of mounting styles: the fixed mount and the movable fixed mount. The kind of spa GFCI breaker you will buy will be greatly determined by the mounting style of the GFCI. As you will most probably have a frame, you will need to match the mounting style of the frame with the hot tub ground fault which you will be buying.

The fixed mount is hardwired into the frame and cannot be removed later. It is slightly less convenient, however much more sturdy. The movable fixed mount is one in which the base is hardwired into the frame, however, the actual GFCI is plugged into it, which can be easily removed later on. If you tend to have GFCIs stop working frequently, it is advisable for you to use the movable fixed mount instead of the fixed mount as it will be more reliable for you.


Voltage Regulation

There are three main voltage regulation categories namely: the low voltage regulator, a medium, and a high voltage regulator. The kind of GFCI you will buy will also be determined by its voltage regulation rating. The low voltage ratings are usually best suited for residential areas. The medium voltage regulators are used mostly in buildings and office settings.

The high-voltage kind is best suited for industrial and other commercial purposes where the requirement of voltage is extremely high to run the enormous machines and tools.



The ground fault circuit interrupter is some of the most convenient and best safety equipment. They are indeed necessary for the entire circuit to work correctly and accordingly. The hot tub GFCI will determine how much secure your house, office or place is. We hope that the product reviews provided and the buying guide will serve you well in picking out the best kind of GFCI for your needs.
