Benefits of Using GFCI Tester

GFCI is the abbreviation of Ground Fault Circuit Interrupter. You’ll find GFCI outlets in your bathroom and, in some cases, in your kitchen as well. These are special outlets, and you can recognize them immediately from the ‘Test’ and ‘Reset’ buttons on them. Here are some benefits of using them.

Ensuring Safety

These mainly serve as protective devices. There are three holes in the GFCI outlets. These are- neutral, hot, and ground holes. If there’s a sudden change in the electrical flow, the outlet will stop providing electricity immediately.

How does this benefit you? Suppose you’re using an electronic appliance in your bathroom, and it accidentally falls onto the bathtub full of water. The electricity flow will spread, and there’s a chance that you might get electrocuted.

Determining Electricity Flow

The GFCI outlet is capable of determining this sudden change in electricity flow, and it can stop providing electricity instantly, saving you from getting electrocuted.

GFCI testers are made especially for testing the GFCI outlets. As these are security devices that are capable of saving you from a fatal accident on a daily basis, it’s important to test them occasionally to make sure they’re fully functional.

The best outlet testers aren’t necessarily expensive. You can get great products at an affordable price, all the more reason for getting them.

The Things to Consider Before Buying GFCI Tester

Buying a GFCI tester isn’t easy, as you’ll need to consider a lot of things before choosing the right product for yourself. You’ll find tons of products on the market, but you won’t find many varieties; at least you won’t be able to tell two products apart judging from their looks. This makes it even tougher.

In this section, we’re going to discuss some of the factors that you’ll need to consider for buying a decent electrical socket tester for yourself. Pay close attention as these can make a lot of difference!

Durability

Durability

Durability is one of the prime aspects that people usually consider while buying an outlet tester. You need an outlet tester that will last for years without any problem and get a tester that won’t even get scratched from a drop is recommended.

There are testers that come with plastic bodies, and there are the ones that come with a layer of padding on them. We highly recommend getting the padded ones, as these come with greater durability and shock resistance.

Some of these padded testers are strong enough to withstand a 7-foot drop even. These will help you in the long run.

Voltage

Voltage

The voltage differs from region to region, which is why buying without considering the required voltage isn’t recommended. Before you get one of these testers, we highly recommend you consider the voltage that’ll be suitable for the outlets of your region.

Compatibility

Compatibilitys

It’s been found that all GCFI outlet testers aren’t universal, and they work differently with different types of outlets. These can hold you back, which is why we recommend getting testers that offer universal compatibility.

Operating Temperature

Operating Temperature

The operating temperature depends on the build quality of the tester. If you’re going to buy one for regular usage, then getting any tester will suffice, as most of them are built to work perfectly in standard weather conditions.

However, if you’re going to use them under extreme conditions, then we suggest you get a tester that offers an operating temperature range that satisfies the ambient temperature range of your workplace.

User-friendliness

User-friendliness

Electrical receptacle testers usually come with a single LED light that indicates whether anything is wrong with the circuit or not. Typically, the tester comes with an indicator chart pasted onto it, and this chart will help you understand the problem.

The better the chart is capable of explaining the problem, the better the tester is.

Design

Design

The design is one of the most crucial factors that you should consider while buying a tester. Many different aspects depend heavily on the design of the product.

At first, we have the grip. The better the design, the more compact the device will be. You won’t want a bulky device as it will be challenging to work with. Then again, sometimes the outlets are in tight spaces. You’ll need slim devices to reach those spaces.

Even if the device isn’t slim, make sure that it’s designed to work with extensions. In such cases, you can reach the outlets easily using the extensions.

How to Use an Outlet Tester

How to Use an Outlet Tester

If you get a standard Outlet tester, then testing will be extremely easy for you. Most of these testers are built like any other electronic device. Imagine plugging your mobile phone’s charger in; plugging in a GFCI tester is as simple as that.

The first thing that you’ll need to determine is which one’s the hot cable. Turn the main power outlet of your home off and open the outlet you want to test.

Here, you’ll find multiple cables of different colors. There’s no need to complicate things by focusing on them. Rather, we recommend putting caps on all of them except one black cable. Usually, there will be two black-colored cables coming out of the outlet.

Now that that’s done, you’ll have to turn the main power back on again. Be very careful, as the next step can lead to an accident if you aren’t cautious. Next up, you need to touch the metal part of the outlet with the black end of the power outlet tester and the exposed black cable with the red end of the tester.

If the exposed wire is the hot wire, then you’ll get a reading. If you aren’t getting a reading, cap the exposed one and test the other cable. The built-in LEDs will help you determine if anything is wrong with the circuit.

Frequently Asked Questions

1. Why Should You Use a GFCI Tester?

GFCI testers are essential for everyone. The GFCI outlets can be life-saving if they function properly, but there’s no saying whether their circuit is intact or not. If the circuit is faulty, they won’t be able to stop you from getting electrocuted.

This is why we highly recommend using a GFCI tester every once in a while. Doing so will help you keep your GFCI outlets intact and functioning.

2. Do You Need a Digital Panel on Your Tester?

It’s not mandatory to have a digital panel on your tester. However, getting one of these can always make things easier for you. Plus, the voltage readers are usually very accurate, and some extra information might come in handy from time to time.

3. Is the Testing Procedure Dangerous?

Not necessarily. The products listed above can be plugged directly into the outlets, and this makes them completely safe to work with. These also come with an on/off button, which makes the process even safer.

4. Do You Need to be a Professional for Using These?

Absolutely not. These devices are designed to be user-friendly, and anyone with zero experience will be capable of using them without any harm. However, you’ll still need some knowledge to understand the readings.
