Garage door openers

[td1963]

What is the code requirement for garage door openers? 4 bay garage should they be separate or can they be grouped together.

Hmmm, I think it has to do with where the doors are located.

Grouping? Are you asking about the switches for the garage door openers?

No 4 garage openers can they be fed as one or do some inspectors want them all independent

One circuit is fine, unless they're wired to operate simultaneously, in which case you should do a load calculation.

What’s the amps on the openers?, what are the size of the doors?, how much will they be used?

In most cases you will be fine, unless they plan to open all 4 a once

I think one circuit would handle them as most are DC motors and don't pull much. But I might be inclined to run two circuits, two doors per circuit, just in case.

I would design it for 2 separate circuits assumin they are cord & plug so that each can be disconnected separately for servicing. What is the amperage for each unit and do the manufacturer's instructions call for anything specific?
