How do you wire a garage door opener?

Answer 1

Garage door openers do not get "wired." They are sold with a standard 3-prong, 120VAC plug that is about two-feet long and plugs into a 15A, 120VAC outlet -- next to the location where the opener is installed. In the absence of a nearby AC outlet, you will need an extension to power you garage door opener.

Well power doesn't get wired the wall mount and sensors do get wired use the directions they will tell you where hook the wires on the back of the opener.

Answer 2

You need to determine what your power requirements are for the garage. This would include general purpose outlets, specific high demand power equipment like air compressors, welders, lifts and so forth, garage door openers and lighting. This will determine what circuits you need and the amperage of each. You will also need to determine the layout of equipment so that the feeds are in the proper location. You then need to determine if you have enough circuits in an existing panel or need to run a subpanel. You also need to know if the amps supplied by the power company are sufficient or if you will have to "heavy up" your service. Do the preliminary design work and then get 3 bids from electrical contractors that you know or are recommended to you by those you trust.
