Most modern garage door openers draw from 3 to 5 amps, depending on what type of lighting your opener has. If your opener has a 200 Watt lighting system, for example, the lights alone will draw just under 2 Amps. Amps x Volts = Watts.
Does a garage door opener need a 20 amp circuit?
No, you don’t need to use a dedicated garage door opener circuit. According to this new change in the NEC 2017, you just need a circuit of 20 Ampere that can supply electricity to the garage. However, you’re not allowed to use the circuit for any other purposes, say lighting the garage.
What size breaker does a garage door opener need?
Unless building codes require higher standards, we recommend using a dedicated 15 amp breaker for a single opener*, and a dedicated 20AMP breaker for 2 or 3 openers. We also recommend a surge protector to protect against power surges.

Can a garage door opener be on a 15 amp circuit?
Most garage door openers use from 350 to 600 Watts, with the average at about 500 Watts. At 500 Watts, the power needed is just over 4 amps. So, a 15 Amp dedicated circuit would be more than adequate for a 6 Amp draw.

As a general guideline, you’d use 12 AWG copper conductors with a 20 ampere breaker, and 14 AWG copper conductors with a 15 ampere breaker. Since the receptacles are in a garage, they’ll have to be GFCI protected. This protection can be provided by a GFCI receptacle, or a GFCI breaker.
Does a garage door opener need a GFCI?
Yes, a garage door opener must have GFCI protection. But a GFCI-protected circuit for the ceiling receptacle was not necessary until the 2008 edition of the National Electrical Code (NEC), so you may find older articles on the web that indicate otherwise.
What gauge wire is used for garage door opener?
041A0323 is a 2 conductor, 22 gauge bell wiring set (red/white) that is used to wire the wall mounted door controls and operation terminals on various garage door openers. Check the manual for your specific model number before ordering to ensure compatibility.
Can I plug my garage door opener into an extension cord?

What voltage does a garage door opener use?
Here in the USA all residential garage door openers use 120v and 60Hz. In many other countries you will find 220v at 50Hz. In some rare countries, like Japan, you’ll find 50Hz in some locations and 60Hz in others. Old openers using AC motors probably have issues.
How many amps does a garage need?

Can I use 14 gauge wire for a garage door opener?
Basically, yes, 14–2 (with ground) should be OK for garage wiring. Be sure that, since 14 gauge wire is rated at 15 amps, that you use 15 amp breakers for each branch circuit. Also check your local codes and see if the Door Opener needs to be on a dedicated branch circuit.
What power supply do I need for a garage door?
Power should be supplied via a 13 amp switched fused spur or a 13 amp switched plug socket. Plugs and spurs should be fitted with a 3 amp fuse. Ensure power is switched off before any electrical connections are attempted.
Can a garage door opener be too powerful?
While a faster motor might not wear down as fast, there aren’t many other benefits to it. However, a potential issue with a powerful opener is if you set the force too high. That could cause the door to get caught on something, and that might damage the door and the opener.
What size motor do I need for a 16 foot garage door?
If you have a wooden or insulated double-car garage door up to 16 feet wide and 8 feet tall, you may want to move up to a 3/4-horsepower opener. For doors that are more than 16 feet wide or very heavy, an even large opener that’s 1 horsepower or higher can reduce strain on the motor.
