wiring diagram for a ground fault interrupter

Installing a ground fault interrupter (GFI) is an important step in protecting your home’s electrical wiring system. Without a GFI, you could be vulnerable to electrocution or fire caused by faulty wiring. Fortunately, wiring a GFI isn’t complicated — all you need is the right wiring diagram and a few tools.

Before you get started, it’s important to remember that it’s always best to hire a professional electrician if you’re not familiar with wiring. If you decide to do it yourself, make sure to familiarize yourself with the basics of electrical safety. Now, let’s look at how to wire a GFI.

In most cases, the wiring diagram for the GFI will be included with the unit itself. It’s important to read through the instructions carefully before beginning so that you know exactly what you need to do. Once you’ve done that, lay out the materials you’ll be using, including the GFI, its associated wiring, and any additional outlets or switches that are part of the circuit.

Start by disconnecting the power from the circuit. This can usually be accomplished by turning off the main breaker. Then, locate the ‘hot’ and ‘neutral’ wires in the box. Make sure to mark the hot wires clearly before disassembling them, as they’re the ones carrying electricity and should always be treated with caution. Next, connect the GFI according to the wiring diagram and screw it into the wall. Finally, re-connect the wires you disconnected earlier and turn the breaker back on.

Although the wiring process for GFIs may seem intimidating at first, it really doesn’t require much technical knowledge. After just a few hours of work, you’ll have peace of mind knowing that your home’s electrical wiring is now safe.
