Gfci is for people protection (5 ma) and gfpe is for equipment protection (30 ma). Had a conversation here recently with a guy that claimed that some electricians were allowed to SWITCH the gfci (5 ma) breaker for the gfpe (30 ma) breaker in a kitchen because the (NEW)freezers and refrigerators were tripping them.
Full Answer
What is the difference between GFCI and gfpe?
Ground fault protection - GFCI or GFPE - there is a difference Abstract: A ground-fault circuit-interrupter (GFCI) is an electrical device, either a receptacle or circuit breaker, which is designed to protect people from electric shock. GFCI protection should not be confused with ground-fault protection for equipment or grounding in general.
What is the difference between GFCI and AFCI protection?
Either GFCI or AFCI protection could save your home—or even your life or that of a loved one. GFCI stands for ground-fault circuit interrupter, and an AFCI is an arc-fault circuit interrupter. These devices prevent electrical shock, injury, and property damage.
What is the difference between a GFI and GFCI breaker?
This would be a GFCI breaker on your electric distribution panel and will protect multiple outlets. A GFI is a local Ground Fault Interrupter, it is at the outlet and not on the panel. So the slight difference here is whether you have protection over several outlets, that you reset at your panel, or single protection that you reset at the outlet.
What is the exception to the GFCI rule?
Exception No. 1 to (3) and (4): Receptacles that are not readily accessible and are supplied from a dedicated branch circuit for electric snow-melting or deicing equipment shall be permitted to be installed without GFCI protection. Your installation may qualify for this exception to 210.8 (B) (4)....

What is GFPE used for?
GFPE is not used for kitchen equipment but is commonly used to protect roof de-icing cable. If it is not used for Commercial kitchen equipment, we are not talking about the same thing. I am not sure that there is any GFPE type of receptacles. Our units are 120V and come with a cord and plug standard 5-15P.
What is the NEC code for ground fault protection?
210.8 (B) (2) requires all 125 volt 15 and 20 amp receptacles to have ground fault protection for personnel, which is defined in the NEC as a Class A device with a trip threshold of 4 to 6 milliamps. If the inspector was to approve GFPE protection which has a trip threshold of 30 to 50 milliamps IMHO that would constitute negligence on his part.
Why do commercial kitchens have GFCI protection?
The reason for GFCI protection in a commercial kitchen has to do with the wash down procedures and the fact that we are dealing with very conductive surfaces. The substantiation was a case where a janitor was mopping down the area in a commercial kitchen and touched a stainless steel appliance. The appliance had a broken ground prong on the cord and the motor in the appliance had faulted out to the frame. The janitor touched the appliance and was killed.
Is GFCi a 5 or 30 ma?
That gfci is a '5 ma' not the '30 ma' . They only say this is for equipment and the people won't be using that outlet much and that section was meant for outlets people can use frequently. Also, there is no 'specific statement in the code that says what the 'ma' should be' in that section, only that gfci is required.
Can an indicator light replace GFCI?
Most of the times the loss of the equipment grounding conductor occurs in the equipment plugged into the receptacle so an indicator light on the receptacle would not accomplish much in the way of safety and would never replace the safety provided by GFCI protection.
How to test a GFCI?
A: Testing a GFCI outlet is easy and should be done regularly. Start by plugging a light into the outlet and switch it on. Press the “TEST” button on the outlet (or distribution panel). You should see the reset button move to the outer position and the light will go out. This means the GFCI is working properly and you’ll need to press the reset button to restore power. If the light remains on, the GFCI protector needs to be replaced.
How to test GFCI circuit?
You can test the circuit by plugging a light into the outlet. If the light works and the circuit does not trip, you know that the GFCI and internal wiring is fine. This means that there is problem with one of the appliances plugged into that circuit. You will need to test all appliances one by one.
What happens when you press the test button on a GFCI breaker?
The user is protected by an insulted test button. When the test button is pressed, the GFCI breaker should open immediately. In other words, the GFCI will trip. Testing should be conducted regularly and the GFI outlet or GFCI breaker should be replaced if it is not functioning correctly.
