How many amps does a bathroom exhaust fan draw?
Generally, bathroom exhaust fans use a 15-amp circuit breaker. Although for exhaust fans with heaters, a 20-amp circuit breaker is preferable as it consumes more power. The usual requirement for a regular exhaust fan is 1 watt per 3 CFM or 5 CFM (Cubic Feet Per Minute).
Does a bathroom fan need its own circuit?
Bathroom Circuits
If the vent fan has a built-in heater, it must have its own 20-amp circuit. This is called a “dedicated” circuit because it serves only one appliance or fixture. Heat lamps, wall heaters, and other built-in heating appliances may also require dedicated circuits.
Can I use 14 2 wire in a bathroom?
Bathrooms typically require dedicated 20A circuits, but that has no bearing on how much power your fan consumes. As long as the voltage is correct the fan will only draw what it needs assuming the wiring to it has sufficient capacity, which both 12/2 and 14/2 do.

How many amps does a ceiling fan pull?
The majority of modern ceiling fans use less than an amp, averaging between 0.5 and 1 amp, depending on the model and the setting. One amp drawn by a ceiling fan is equivalent to about 120 watts. Low settings use less amperage while higher settings use more.
Can bathroom fan and light be on same circuit?
This is acceptable. Many bathroom fans include lights with the intention of both being wired to one switch on the same circuit. They can also be wired separately to different switches.
Can I wire a bathroom fan to the light switch?
Wiring a bathroom fan to a light switch is very straightforward. If the bathroom fan and light are separate fixtures, you’ll need a short wire to connect the two. Turn the power off, connect the white wires, connect the black wires, ensure it’s grounded, turn the power back on, and you’re good to go.
Can you wire outlets and lights on the same circuit for a bathroom?
No lighting outlets or other equipment can be fed from the same circuit feeding the bathroom receptacles. For example, a one-family dwelling has two bathrooms and a duplex receptacle has been installed in each. One 20-ampere branch circuit can supply power to both bathroom receptacles but cannot feed anything else.
What size wire do I need for a bathroom fan?
Wiring Considerations
Most bathroom ventilation fans use a 15-amp circuit breaker and 14-gauge wiring. Due to the increased power drawn, fans with heaters usually require a 20-amp circuit breaker and 12-gauge wiring.
