When the electrician merely replaces a normal outlet receptacle with a GFCI (ground-fault circuit interrupter), the procedure is simple and inexpensive, costing between $120 and $150 for the service call and a little amount of work. However, if the electrician has to also replace the wiring in the room, then this requires more work and can cost more than $200. Before you hire an electrician, make sure you understand what will be done in your house when he completes his inspection.
The average price of an electrician is about $180 and usually includes charges for inspections, labor, and materials. Other factors that may affect the cost are the size of the job and the location of the residence. For example, an electrician who needs to dig a new conduit hole for a cable replacement operation will charge more than one who can use existing holes. If there's a problem with electrical work already performed, such as bad connections or broken wires, the electrician should identify the cause and report it to you before starting work. He should also check all wiring and equipment for signs of wear and tear. If something looks amiss, he should stop working until it is fixed.
Installing a ground-fault circuit breaker (GFCI) is very easy for any homeowner to do. They're like regular outlets but they detect any electricity that flows through someone accidentally touching both sides of a wire.
The Average National Cost of Installing a GFCI Outlet The average national material cost to install a GFCI outlet is $19.71 per receptacle, with a price range of $17.68 to $21.74. The total labor and material cost per receptacle is $154.04, which falls between $140.26 and $167.83. The national average cost for replacing a GFCI outlet is $113.09.

GFCI stands for ground-fault circuit interrupter. It's a standard safety feature on most households' electrical outlets used for lighting fixtures, hair dryers, irons, and other small appliances. The GFCI function prevents electric shocks by shutting off the power before someone gets hurt. If you have a problem appliance that isn't working properly due to a dead circuit, a GFCI outlet can help prevent accidents caused by exposed live wires.
Replacing a GFCI outlet is easy. First, turn off the power at the breaker panel if there is no power indicator on the GFCI itself. Then, locate the hot wire coming into the outlet and connect it to the hot terminal on a replacement outlet. Next, connect the black wire from the replacement outlet to the black wire on the broken outlet.
The average cost of installing or upgrading an electrical outlet in the United States is $212. A new one might be as little as $75 or as much as $485. The project normally costs between $133 and $295. Depending on the kind, each receptacle unit will cost between $3 and $50. Installing them is the most expensive part of the job.
Receptacles are available in three types: fixed, modular, and surface-mounted. Fixed outlets are housed in a single metal box that cannot be moved. They are cheap and easy to install, but they look like standard light switches so they may not be appropriate for all rooms. Modular outlets can be installed in any number of locations within a room, so they're great for adding cable channels or computer networks. Their only limitation is that they must be placed directly against a wall. Surface-mounted outlets are the most expensive option but they can be removed if needed. They are sold in sets of either two or four and can be installed anywhere in the room.
The average home has 12-20 receptacles, depending on how many appliances need electricity at once. If you plan to add devices such as cell phones, cameras, or heaters, you'll need more than one outlet for each type. For example, a family of four needs at least five 120-volt outlets, since that's the maximum voltage for a household circuit.
