GFCIs are generally installed where electrical circuits may accidentally come into contact with water. They are most often found in kitchens, bath and laundry rooms, or even out-of-doors or in the garage where electric power tools might be used.
When would you use a GFCI outlet?
GFCI protection is required for 125-volt to 250-volt receptacles supplied by single-phase branch circuits rated 150 volts or less to the ground. GFCI receptacles are required in bathrooms, garages, crawl spaces, basements, laundry rooms and areas where a water source is present.
Do I connect GFCI to line or load?
When you connect only to the line terminals, the outlet provides GFCI protection only for itself. When you connect to both the line and the load terminals, the outlet protects itself and any additional outlets farther down on the same electrical circuit.
What is the difference between load and line?
The line side of an outlet is where you connect the incoming source power. The load side is where the power leaves the device (or electrical box) and travels down the circuit.
What is the difference between load and hot wire?
Line is the wire that goes from a source to a switch. It’s upstream of the switched device. Line is very hot. The wire from the switch to the device is called load.
Do you need GFCI in kitchen?
In kitchens, all outlets that serve countertop surfaces should be equipped with GFCI outlet protection. That would include any outlets on walls, behind wet areas (sinks, etc.) that have features such as countertop breakfast bars (open counter surfaces above sinks used to sit at on the opposite side).
Can I use 15 amp GFCI in kitchen?
Requirement: All 15 amp and 20 amp outlets, whether GFCI or not, must be tamper-resistant in the following kitchen-related places: small appliance circuit, countertop space, wall, and hallway space. Why: If you have not done electrical work for a few years, you may be surprised by this requirement.
When did GFCI become required in kitchen?
Receptacles in the kitchen were first required to be GFCI-protected by the 1987 edition of the National Electrical Code (NEC), and initially only for counter receptacles within 6 feet of a sink. That was expanded to include all kitchen countertop receptacles with the 1996 NEC.
What happens if you mix up line and load on GFCI?
If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will not reset and will not provide power to either the GFCI receptacle face or any receptacles fed from the GFCI.
Will a GFCI work if the line and load are reversed?
Here’s what happens when somebody wires a GFCI receptacle with the load and line wires reversed: The GFCI will work, in the sense that you can plug in a hair dryer and the hair dryer will blow hot air.If the load and line wiring gets messed up, a ground fault (radio in the tub) won’t trip the GFCI.
Does a GFCI have to be the first outlet?
GFCI doesn’t have to be the first in line because placing the GFCI first in line will trip whenever something goes wrong with any of the outlets downstream. While placing the GFCI first in line will protect all the other outlets downstream.
Which black wire is the load?
White and grey wires are neutral; green with yellow stripes, green and copper are ground wires, black can be line/upstream wire, red or black are load/downstream. The white or black are travelers.
How many GFCI outlets can you have on the same circuit?
You only need 1 GFCI outlet per circuit (assuming it’s at the beginning of the line and the rest of the outlets are loads). They are correctly wired in parallel – if they were in series, you wouldn’t get the correct voltage at the other outlets when there is any type of load present.
Is load wire white or black?
So, what color is the load wire? Load wires are mostly black, but red can also be used as a secondary load wire. They are also connected to the switch’s top half, while line wires are connected to the switch’s bottom half.
Is a switch a load?
A load switch is simply a switch, mechanical or electronic, that connects or disconnects a load to the high side of a power source. A wall light switch is a load switch. Any off/on switch on an appliance or electronic product is a load switch. A relay can be a load switch.
What does load mean in electrical?
An electrical load is simply any component of a circuit that consumes power or energy. In a household setting, the most obvious examples of electrical loads include light bulbs and appliances.
Does a refrigerator need a GFCI?
Residential Kitchen
In a dwelling unit (residential), GFCI protection is only required for kitchen receptacles that serve the countertop surfaces. There’s no requirement to GFCI protect receptacles that serve a refrigerator. Unless the fridge is plugged into a countertop receptacle.
Does a dishwasher need GFCI protection?
GFCI protection is not required for receptacles serving appliances like dishwashers, or convenience receptacles that do not supply countertop surfaces. Receptacles installed within 6 ft of the outside edge of a wet bar sink must also be GFCI-protected [210.8(A)(7)].
Does a microwave need a GFCI?
A GFI or GFCI outlet is needed if the microwave is located less than 6 feet from a water source such as the edge of the sink, toilet, shower, etc. It is also needed if located outdoors, garages, kitchen counter tops, near laundry, utility sinks, wet bar sinks and near swimming pools.
What happens if you put a 15 amp GFCI outlet on a 20 amp circuit?
4 Answers. Yes you can. Having the GFCI marked 20 Amp is so the one model can be used for either type of circuit. If you have a 20 Amp Circuit then there is no problem with using 15 Amp receptacles on the same run.
What happens when you put a 15 amp receptacle on a 20 amp circuit?
Nothing will happen. Some people think that you ran the risk of overloading the outlet, causing it to overheat before starting a fire. You cannot completely ignore this concern. An appliance that should only draw 15 Amps can suffer a malfunction, causing it to pull more current than is safe.
