Different styles of 220 volt recepticles?

MrLinux

My new garage comes pre-wired with 3 different styles of 220 volt
receptacles. I am almost certain that they are 220 volt... my Panel
has 3, 220 'garage' circuits labeled... and these are not standard 110
type wall receptacles... ( Standard for US/Texas )

the s6300045.jpg one is mounted about 9 feet off the ground.. sort of
looks like a 110 volt one, but its got that 'side' part to it... The rest
of the plugs ( including the 6 ceiling mounted ones ) are all 110 looking
ones...

are these pictured, 220 volt... and if so... why the different styles?
Do they mean anything or does 220 equipment just come with
random style plugs so they tried to cover all of the bases?

They reflect the amperage of the circuit and the voltage of the power supplied. (Or at least they should)

Image 44 is a 6-20r for a 240 volt 20 amp circuit only

Image 45 is a 5-20r for a 120 volt 20 amp circuit

Image 46 is a 14-50r 120/240 volt 50 amp circuit ususally for a range

You can get a one piece cover plate for image 44.

So is this a new house or just new to you? I figured the 9' high 120v recepticle might be for a garage door opener but you say you have six 120 v recepticles in the ceiling too?

The 220 v recepticles were probably put in for shop equipment of some type. Now you also have a puzzle if you have three 220 circuits in the box labeled garage because you've only found where two of them go.

One of these double pole breakers may be a multiwire circuit, feeding the single 120V receptacle and other 120V receptacles in the garage. Although not required in this case, many electricians put multiwire circuits on a double pole breaker.

Just your typical Texas sized, 3-car garage:
800 square feet
12' Ceiling
17 ( give or take a few ) wall / ceiling receptacles.
2-car Industrial type rollup-door
1-car standard garage door
central vac ( the vac is for the whole house, but the garage
has a couple of inlets )
central air ( the house has 3 units / zones... one is just for the
garage and my 12x18 home office / media room)

The original owner/design was a car guy's garage... going to have a
lift and other car things... that guy never took ownership of the
property and it's been little used over the years. Quite a change
from the 2-car garage I've had for the last 15+ years. This will
be a nice change of pace.

Getting a garage door opener for the 2-car rollup door will be a challenge...
right now it's on a pull chain. I also don't have a lot of attic storage
because of the 12 ceiling.... I would have been happy with a 8 foot ceiling
and 800 square feet. I'm going to have to put up some type of loft
storage for my christmas tree / lights / and what not.

Sounds like a nice garage and that being designed for a car guy explains the electric. Too bad he didn't get the lift in - that would be a nice luxury. You definitey could put in a storage loft to use some of that 12' height.

That's how big my HOUSE is....WITH garage.

Shouldn't be a problem at all. If all else fails, call a company that installs commercial doors. This type of door is common in commercial use and openers are installed on many of them.
