Wiring question

How can a wire a switch that controls a plugin with the power at the plug? Any pictures would help.
 
Just install a switch between the fuse/breaker box and the outlet.

Here I am using

Red = Hot/Line
Blue = Netural

I did not show the ground wire. For you should know where it attaches. Also this will disconnect the entire outlet once the switch is thrown.

I can also make a drawing of how to wire the outlet so that only one socket is switched (Top) and the bottom socket stays hot when the switch is turned off if you need it.
 
Not sure exactly what you are trying to do. An outlet has a thin strip of metal connecting the top of the outlet to the bottom of the outlet. If you cut this strip off it separates the top from the bottom like it was two outlets. You can wire one to power and the other to work off of a switch.
 
Have not read the NEC in a while but as I recall the switch must disconnect the hot wire or both hot & neutral in some cases.

You're correct. Dont know what I was thinking. Guess I am so use to wiring them in the apartment complexes that we rehab that my brain passed gas..
 
Rkh; I read your question differently than everyone who has answered so far, so statistically that makes it more likely that I'm the one who is misunderstanding. What I took your question to mean is how do you make an outlet switched when the power comes in at the outlet rather than at the switch? Is that what you're asking? Here's how you do that:

1) Assuming that there is a 12/2 cable between the outlet and the switch, disconnect the incoming power at the outlet, the black wire if it's wired correctly, and connect that to the black wire running to the switch.
2) Connect this (black) hot wire from the outlet to one side of the switch.
3) Connect the white wire in the switchbox to the other side of the switch. Put black electrical tape, black paint, or black magic marker on this white wire to show that it is now a hot wire.
4) Connect the other end of this white wire to the hot side of the outlet. Make it black to show that it is now a hot wire.

Correct to code is to use the white wire (marked black in some way) to the power source and then send the current back to the user end via the black wire.
 
If it?s an explosion proof circuit such as gas pumps both hot $ neutral are disconnected by NEC as I recall. There is a special circuit breaker that is made for that purpose.
 
An "Electrical" question hmmmmmmmmm

The NEC may have changed since I practiced power distribution but in my day we NEVER switched the Neutral. In my home I had some of those duplex fixtures with a switch on one half and an outlet on the other which may or may not be used to accomplish whatever it is you're trying to do.

If you have a two wire going to a switch you always feed the hot onto the white wire [it is not a neutral] It is a switch leg. That way the black wire coming off the load side of the switch is the hot at the light socket. No marking of the white is required by code and any electrician going in the box will understand it. The diagrams posted are not reality.

Want a split switched or switch the entire receptacle ? You can even do it with a two pole breaker so the receptacle can carry twice as much power .

I read the question as Stan did....and it seems to me he answered that question.
