What Are The Different Types Of GFCI?

What is a WR GFCI?

Weather Resistant Receptacles offer protection from rain, snow, ice, moisture, and humidity when properly installed in an approved weather protective or while-inuse cover.

Designed with enhanced nylon and corrosion resistant metal components Weather resistant receptacles are extra durable..

Should I get a 15 or 20 amp GFCI outlet?

1) You can have a GFI receptacle on either a 15 or 20A circuit. Keep in mind, areas like kitchens, bathrooms, laundry, etc, typically require 20A circuits for receptacles. For areas like outside and garages 20A circuits are always a good idea.

When should a GFCI trip?

When the amount going differs from the amount returning by approximately 5 milliamperes, the GFCI interrupts the current. The GFCI is rated to trip quickly enough to prevent an electrical incident. If it is properly installed and maintained, this will happen as soon as the faulty tool is plugged in.

Can you put a refrigerator on a GFCI?

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.

How far does a GFCI have to be from a kitchen sink?

3 feetIt must be a GFCI, and it must be within 3 feet of the edge of the sink. Either behind or beside the sink is acceptable — across from the sink on an opposite wall is not.

Where should a GFCI be placed in a 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).

Are all GFCI the same?

There is no difference. Ground fault circuit interrupters (GFCI) and ground fault interrupters (GFI) are the exact same device under slightly different names. Though GFCI is more commonly used than GFI, the terms are interchangeable.

Does every outlet in a kitchen need to be GFCI?

Kitchens: All receptacles serving countertop areas and any receptacle within 6 feet of a sink must have GFCI protection. … Laundry, utility, and wet bar sinks: Where receptacles are placed within 6 feet of the outside edge of the sink, they require GFCI protection.

How many outlets can one GFCI protect?

There’s no limit. A standard GFCI will protect up to 20 amps, drawn from any combination of receptacles, either the built-in one or any number of additional ones connected to its load terminals.

Can I put a GFCI anywhere in a circuit?

You can replace almost any electrical outlet with a GFCI outlet. Correctly wired GFCIs will also protect other outlets on the same circuit. While it’s common to find GFCI outlets in bathrooms and kitchens, there are GFCI outlet requirements.

Which is better GFCI outlet or breaker?

If you will have receptacles that need GFCI protection in these locations, use a GFCI breaker. GFCI receptacles are easier to install. … If money is an issue and you only need to protect a single location, a GFCI outlet might a better choice than a GFCI breaker.

How far can you run 12 gauge wire on a 20 amp circuit?

The total circuit would be about 60 -70 feet in length. It would only be supplying about 5 outlets and one light. It would be a light load, running small things, no heaters or med/large equipment. #12 provides reasonable performance up to about 100′ with general loads like you describe.

How many outlets can you put on a 15 amp breaker?

8 outletsTechnically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.

What is the difference between a class A GFCI and a Class B GFCI?

There is a Class A GFCI that trips when a ground fault current exceeds 5 milliamps and there is a Class B GFCI that trips when a ground fault current exceeds 20 milliamps. … Therefore, a Class B device with a higher trip current was permitted. Another GFCI-Type device is an appliance leakage current interrupter (ALCI).

Can you have 2 GFCI outlets on the same circuit?

To save money, you can put in a single GFCI and then wire additional standard outlets to the “LOAD” output from the single GFCI. … This provides the same protection as having a GFCI at each location.

Is there a difference between indoor and outdoor GFCI?

Outdoor electrical outlets differ from indoor outlets because they have watertight covers that protect the outlet even with a cord plugged in. … GFCI outlets trip and turn off automatically when there’s a current leakage or short circuit, which helps prevent fires and accidental shocks.

How many milliamps does it take to trip a GFCI?

It takes a mismatch of about 5 mA of current (5 milliamps or . 005 A) to trip a GFCI. GFCI receptacles can provide protection to standard receptacles connected to the load side of the GFCI.

What type of GFCI outlet do I need?

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.

What type of GFCI do I need for my bathroom?

The National Electric Code states that, at a minimum, a bathroom needs one GFCI-protected outlet. It’s recommended that each bathroom has two or three GFCI protected outlets. The number of outlets you choose to protect is up to you, as long as you have at least one GFCI protected outlet in a bathroom.

Will a GFCI trip on overcurrent?

A GFCI detects the difference in the current between the hot and neutral conductors. … Because the current sensor that a GFCI uses can only sense the difference in current between the hot and neutral conductors, not the overall current, it will not trip on an overcurrent.
