240V Receptacle?
- Thread starter Tyga

Yes there are
Aside from the different configurations for the various amperage ratings of the receptacles, there are also 3 and 4-wire receptacles. 3-wire is a straight 240v with a ground, and the 4-wire is 120/240v (it carries a neutral so that you get 120v between the neutral and either hot leg) with a ground. This one is probably rated at 40 to 50 amps, 240v only. There should be an amperage rating molded into the cover, but I can't read it in your picture.
Okay I'm going to try to take a closer look today... it's just so hard squeeze into the space since there's so much clutter in the basement haha. That's why the pic is so blurry. Thank's for the help rives. I'm pretty sure there is only 1 double pole breaker in my panel also so I could read the amperage off that. I would love to run my light off this just so I could utilize the other 2 15A circuit's to really dial in the set-up with an A/C and some more lighting for veg
Well, it is possible that they have a 4th wire tucked away in there and didn't use it, but since the receptacle only has 3 openings in it, it is pretty safe to assume that you only have 3 wires feeding it.
If it says 120/240 it may be old enough that it doesn't have a ground wire. Is this a pretty old house? You will need to pop the cover off and see if the there is a bare wire or if they are all insulated. You could also go to the main panel and find the wire coming from this receptacle and see what's what.
Okay i'll check it out... Im pretty sure there is a ground though because all the other circuits im the house do. Will that determine weather i can use it or not?
There should always be a gnd. red, black, gnd or copper this is normally 240v. You need to find out what is feeding that outlet.. Size of breaker
rives is that very old or just dirty??. Do you know what year they changed over? My home was built in 73. The outlet I had behind my dryer was like that looked different before I replaced it to a new one. It had 3 wires red,blk,copper
HH, I don't know, that's why I asked up above about the house's age. Houses from the '70's should all be grounded, I think that residential grounding started being widely used in the early '60's, but I'm not certain.
I was surprised when he said that it was marked 120/240 - that should mean that it is both, not either one. If that is the case, then the third wire would be a neutral, not a ground.

Your probably corect It looks like Romex going to that..
use a multimeter and see what the voltage is. you should have 2 120v and a gnd...that makes 240v. You can also turn off the power to that oultlet open it to see what color wires are there. pic would help
Couldn't figure out how to get the front panel of the receptacle off.... the only screws I could find on the whole thing was the ground clamp? But I snapped some pic's of the wire that's feeding the receptacle and then a quick flick of the panel. I was trying to follow the wires in the panel that were feeding the breaker but it's just to much of a mess in there... -.-
The cord reads " Jlcan S Stabiloy SE Cable style U Type xhhw cdrs 600V 3CDRS 6 al (UL) 1984.
Safe to assume there's a ground? 1984? Didn't somebody state that all the wiring done after the 60's were required to have a ground?
