Why is Only Half of the Outlet Working
How to Wire a Half Hot Outlet and Switched Outlet: I have a problem with a duplex receptacle where the upper plug does not have power but the lower half does.
How a Switched Outlet Works
[ad#block] Electrical Question: I have a problem with a duplex receptacle where the upper plug does not have power but the lower half does.
- I took the cover off and found this:
- On the BRASS screws on the right side, a BLACK wire comes to the upper brass screw, and a RED wire comes to the lower brass screw.
- On the neutral side there is one WHITE wire being used to span the gap between the 2 silver colored screws and the little brass tab has been broken off between them?
- The lower plug in still works, so do I simply replace the plug making sure to wire it the same way?
- It has been working for years this way and just stopped today.
- I am not sure though if the brass tab has been broken on the brass screw side where the RED and BLACK wires feed?
This electrical question came from Ron, in Portage La Prairie, Manitoba, Canada.
Thanks for your electrical question Ron.
