Sharing outlet with Garage Door Opener

Mine shared a line with the freezer. It was no big deal.

You want certainty, just buy a Kill-A-Watt meter for $15. That will show you the draw from the opener won't be a concern.

 

Should NOT be a problem........unless maybe it is a really HEAVY door with an industrial opener on it.

BUT.....it might be a good idea to be prepared.....by finding out where the breaker is located.

 

no problem at all. worst you can do is blow the breaker. and don't forget, you have an 8 amp option

 

it should be in the menu

 

Look for this...

 

Easiest solution is to test it out.

First thing is to check the outlet. Make sure that it looks in good condition, with no noticeable damage or rust. I'd also recommend picking up an outlet/GFCI tester (Amazon.com: Receptable Tester) and check the outlet. I do it to every place I live in and you'd be surprised how often I find miswired/poorly wired outlets.

After that, locate the breaker box, plug the Prime at max current, and open and close the door a few times. Breaker popping should be pretty noticeable. If you see/hear/smell something off, you can run to the breaker and flip the circuit off manually.

Another good check is to confirm what is and isn't on the same circuit. Turn the circuit off at the breaker box and then go around your garage/adjacent rooms and check each switch and outlet. If you find another outlet/switch connected to the same circuit, either repeat the above test with the additional items on the circuit or ensure that you don't put any heavy loads on those outlets/switches. Some child-proof outlet plug covers would do the trick nicely.

And welcome to the Prime family!

 

If it's a NEMA 5-20R receptacle (20A, T-shaped neutral socket) then it's probably a 20A circuit (unless it was incorrectly wired) and it's almost certainly fine to charge at 12A on the same circuit unless it's a large industrial garage opener. Commercial buildings are often wired with 20A circuits instead of 15A, so there's a good chance you'll find one in an apartment building.

If it's NEMA 5-15R then that's inconclusive since it could be a 15A or 20A circuit.

 

If only other thing on the circuit is a garage door opener, you should be fine even with 15A circuit. The question is, how difficult is it for you to check to see if anything else is on the same circuit? Just because one outlet in the single car garage has only a garage door opener plugged in does not mean there are other outlets outside of the garage that is on the same circuit. If you have an access to the breaker box, you can just test to see if it can handle the charging.
