Frequently Asked Questions
Does a powder room need a GFCI outlet?
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.
Can a bathroom circuit serve the outlets in a laundry room?
Other than the laundry receptacle outlet or outlets, the laundry branch circuit is not permitted to supply any other outlets. In other words, the laundry branch circuit cannot supply living room or kitchen outlets, even where these rooms are adjacent to the laundry area.
Does a bathroom GFCI need to be dedicated?
The minimum requirement for outlet receptacles in a bathroom is one GFCI-protected receptacle served by a 20-amp circuit. This is a bare minimum, however, and most bathrooms will have at least two receptacles, and often as many of four or five.
Can a GFCI be used on a 20A circuit?
If it's not, the answer is no. You want to avoid wiring the fixtures and the receptacles on the same electrical circuit. ZenFixIt says this changes when a 20A circuit powers a single bathroom. “Outlets for other equipment within the same bathroom” can then work on that same circuit.
