1 outlet / 2 switches: want to replace old outlet with GFCI




Last Updated November 12, 2017 17:21 PM

Old house build in 1958. City inspector ask me to replace outlet in bathroom and kitchen to gfci, and say he will check if wire correctly or not. When I connect gfci, there are two problem: 1. gfci outlet is bigger than old one, cann't fit. 2 gfci outlet have grounding screw, but wire from box has no grounding wire. question: 1.Should I cut wall to change a bigger box to fit gfci outlet. 2.Just connect it without grounding is OK?

The first problem is common with older homes. I usually extract the old (likely metal) box surgically by cutting the mounting nails inside the box, and then I install a winged remodeler (old work) box, which is much larger.

You'd only use the grounding screw on your new outlet if 1) there's a grounding conductor in the cable, or 2) you need to ground to a metal box which itself is grounded. Neither apply to you. It is acceptable to install ungrounded GFCI...

Your GFI outlet has five different connectors, and it's important to know which is used for what.

The ground screw is connected to the ground wires coming and going to the box.

There are two sets of connectors for hot (black) and neutral (white) wires. One set, labeled LINE, is used for power coming in to the box, and the other, labeled LOAD, for outlets that will be "downstream" of the GFCI, and be protected by it. Make sure you know which is which- the old outlet will be labeled, as will the new.

If you can't see the markings on the old outlet, turn the power on briefly, and use your non-contact tester to find the hot wire- that's the one bringing power into the box. You'll connect that wire, and its white companion, to the LINE connectors. (And then turn the power off again.)

This GFCI outlet has both push-in and screw terminal connectors; some old timers (and some new-timers) will only use the screw terminals, but actually, the push-in connectors are...

This post is over ten years old but I'm posting an update for anyone reaching it via a web search. Some of the information provided previously is incorrect. A GFCI works by constantly sensing the current running though both the hot and neutral wires. If there is even the slightest difference between the two, the circuit is shut off immediately.

Therefore if any current is flowing from the hot wire to ground instead of back through the neutral wire the power will be instantly disconnected. That is why no ground wire is needed.

Also, it is usually NOT necessessary to replace EVERY ungrounded outlet with a CFGI outlet. Typically several outlets are on the same circuit. As long as the FIRST outlet in the chain that has its power coming directly from the circuit breaker is a GFCI, then the rest of the outlets on the circuit AFTER the GFCI outlet are also protected by it.

This is why is is critical that ALL of the following be identified correctly:
1) Hot...

Determine which devices are not connected to GFCI.

Some devices should not be connected to GFCI receptacles because of the possibility for "nuisance tripping"; for example, refrigerators, fluorescent lights, laser printers, garbage disposals, trash compactors, dishwashers, clothes washers and dryers, home heating and cooling systems, artesian well and driven point jet type pumps,microwave ovens and freezers are some of the more commons items.

For switches: Label the wires with some sort of identifying mark on masking tape wrapped around each wire. Use the same mark for each wire connected to the same terminal screw of the device Determine the type of switch you have. A single-pole switch (one switch controls the light fixture(s)) will have two screws and be marked "ON" and "OFF" if a toggle type, a 3-way switch (two switches control the light fixture(s), typically at each end of a stairwell) will have three screws, one of which is black, and a 4-way switch (three switches...

For bathroom outlets, you should install a ground fault circuit interrupter (GFCI). This project is in the Chicago area with metal conduit.

This device will prevent shocks and possible electrocution by detecting small changes in current and shutting off the power. The GFCI can turn off the power in a fraction of a second and detect smaller amount of electricity than your circuit breaker.

In this weeks edition of BS with AJ, I show you how to remove and replace a regular electrical outlet with a GFCI (ground fault circuit interrupter) outlet. Electrical outlets go by a few different names outlet, receptacles. Some even call them plug's or plug in's, which is the proper term for the male cord end the plugs into an outlet or receptacle. But what ever you call them ill show you how to replace them! The reason to replace or upgrade from a regular outlet to a GFCI outlet is to protect us from receiving electric shocks from faults in the electrical devices wee use in our home. These are generally installed in area's subject to moisture, since moisture greatly increases the danger of accidental shock. Places to install a GFCI outlet include but are not limited to bathrooms, garages and accessory buildings, all exterior receptacles, crawl spaces, unfinished basements, kitchens, laundry, utility, wet bar sink areas and boat houses.
Here are some tools...

At least 200 people will be saved from death due to electrocutions if all houses in the United States have the ground fault circuit interrupter or GFCI. That is why the law requires the installation of outlets with GFCI in some areas of the house, especially outside, near the pool, bathroom, comfort room, and kitchen. Replacing an electrical outlet with a GFCI may or may not be about following the law. But doing so will surely improve safety of your house. You may hire a professional electrician to perform the job, though it’s not needed for an easy job like this. Here’s how to replace an electrical outlet with a receptacle-type GFCI:

Safety first. Turn off the power source to the electrical outlet or better yet, turn off the power source of the house, just to be sure. Look for the breaker panel and then switch off the outlet’s breaker panel. Have a note on the electrical panel that it should not be touched. Now go to the outlet and test its receptacle using a circuit tester....

I am trying to add an outlet and a switch for that outlet. The power goes through to other areas. So basically I have power coming to a junction box, one of the wires coming out of the junction box goes to a light ( the old pull style).

Welcome to the forums!

You're right. Cutting the GFCI off and on will almost certainly mean you'll have to reset it.

If the outlet for your receptacle has a two-conductor feed from the box where the switch is, it should be easy to change the hot conductor for the receptacle from switch control to always hot. You'll need to kill the circuit and pull the switch out of the wall to see how the wires are connected now. Don't disconnect anything until after you've got it figured out - just pull it and have a look.

If, after you do that, the solution isn't obvious to you, post back with a description of the wires and how each is connected. You can include pictures that will show us that information if you think that will help. See How To Include...

Troubleshooting the outlet

When an outlet goes dead, it’s easy to jump to conclusions and assume the worst. But more often than not, the problem is something simple, and you can save the cost of a service call just by taking a few steps to trace the cause. Don’t worry if you’re not comfortable doing electrical work. Better than half the time, you’ll solve the problem without even lifting a tool. We’ll show you how to start your search for the problem by checking in the most likely places. If that doesn’t work, we’ll show you where to look for loose connections that may be to blame, and how to fix them.

Of course, there will always be problems that are best left to an electrician. But if you take these steps first, there’s a good chance you’ll find the solution.

Is Electricity Really Mysterious?

The scientist and the homeowner have two entirely different reasons for saying that electricity is mysterious.

They are probably talking about different things. The scientist is considering some basic principles of nature, which as yet have no deeper explanation. The average person might share such wonder. But when I hear a homeowner say that "electricity" mystifies them, they usually mean that they don't know how to deal with their...
