    Default Wiring a new outlet from existing light switch

    I want to install a new outlet into a wall that only currently has a light switch. Can I run wiring down the wall from the exiting light switch to establish a new outlet? If so, what connections, need to be made? Please be as descriptive as possible as far as the wiring.

    A lot will depend on your current switch / light fixture wiring configuration, and depending on the configuration if a neutral and an unswitched hot is available at the existing switch box location.

    Take a look at the link bellow ....

    http://www.homewiringandmore.com/swi...let/index.html

    see if you can match your switch/fixture wiring configuration to one in this section of the homewiringandmore site.

    Look inside your switch box and see if the white wire is connected to a screw on the side of the switch. If it is NO YOU CAN NOT GET POWER FOR A RECEPTACLE FROM THIS SWITCH.

    Look inside your switch box and see if the white wire is wire nutted to a second white wire neither connected to the switch. If the white does not connect to the switch but instead is wire nutted to a second white wire in that box THEN YES YOU CAN GET POWER FOR A RECEPTACLE FROM THIS SWITCH.

    Try the link Don provided for you after you consider what I said above.

    If the white wire is connected to the switch then you have a hot white wire not a grounded white wire. YOu will have no neutral wire in this box but only hot wires being both black and white being hot wires.

    Hope this helps

    Can you make this connection to a new outlet from the light fixture feed (RD / BL / WH) instead? if so, what would be the connections?

    Depends on where the red black white wire comes from. Is there only one cable in that box or are more cables leaving the box to elsewhere?

    If you have a permenant hot and a permenant white and grounidng wire then yes. Question is you have a black and red wire in that light fixture box. Leads me to believe that if no other cables are in that light box the power source is in the switch and the black and red may be switched hot wires one for a fan and one for a light.

    Where are the red and black and white coming from and are other cables in that box and where to the go to serve?

    To serve a receptacle you need a permenant hot black or red white and bare.

    red black and white (and ground) feeding the fixture.

    at switch whites are capped together, red is at top screw, black at bottom screw then capped with other black

    The black wire connected to another black wire in the switch tells me that this light fixture has a switched red wire and a permenant hot black wire.

    This would tell me that you should be able to install a 12 or 14/2 with ground matching the existing wire size from that light fixture box to the new receptacle. The connect black to black white to white and bare to bare in the light fixture. Then in the receptacle connect black to brass screw and white to silver screw and bare to green screw.

    Should do the job.

    Let us know how you come out.

    Wg SAID:

    Actually if it is a 3-way switch, then you may not be able to easily power a receptacle. For the example "Power Source at one switch and Fixture feed at other switch", Then in Switch #2 you would have neutral wire nutted to second white wire neither connected to the switch. However, no dedicated power line for a new receptacle.

    I just made this mistake on my new kitchen wiring and had to remove some drywall to remedy. It seems that it would be possible if some logic was built into some special 3 way switches. Of course, converting 3-way switches to wireless would allow receptacle from the switch, so statement is correct, but wireless 3-ways seem to limit decorative options.

    Just a thought.
