Installed 15 amp GFI\’s in Kitchen. GFI\’s will not set. Box breaker is 20 amp. Should I have used 20 amp GFI\’s
Yes, never use a 15 amp socket in a 20a service. Is there anything else connected to the same circuit, it shouldn\’t but it could explain why you are not able to set the GFI\’s. Usually a kitchen circuit has 240V into it. If you connect the wires incorrectly, you will never be able to set the GFI.
