Lost power to half the room.


Hello everyone I dont know how but I have lost power to outlets in half of my room. I replaced a regular light switch with a motion detecting light switch in my bathroom. I cut off the power to the room and swapped out the outlets making sure to disconnect and reconnect the wires correctly. when i turned the power on the motion light works fine but I have lost power to the outlets on one side of my bedroom thats connected. I attached a pic to give a better understanding.

Check the receps when the light controlled by the motion sensor is on. You may have mis-spliced the wires in the switch box.

i put the motion switch to the ON position but still got nothing, my next step is to install a normal switch to see if there is not enough power to power a motion switch and the outlets.

You probably just have a loose wire at one of your outlets,and it could be at one of the working outlets. Not really such thing as not having "enough" power to use a motion sensor and outlets. Outlets don't use power - just the devices plugged into them.

could it be that the wire nuts are to big and not tight enough?

Possible. Check each outlet for loose connections. In particular, look for "backstab" connections, where the stripped part of the wire is simply stuck into the back of the outlet (no screw is tightened in these connections). Consider replacing those with "backwire" connections, where you slide the wire under a clamp and tighten the screw.

Usually when a bunch of stuff stops working, a wire is loose somewhere.

If the only piece of equipment that you've had apart is the switch then definately start there....double and triple check everything in that box. It would be a pretty wild coincidence if another fault on the line just happened to occur when you swaped out the switch.

It's very hard for anyone here to help you without a more complete description of what you have done. Perhaps some photos would help.

There is a diagram up top. really all i did was install a motion detecting switch in my bathroom wired it up the to black > black. black > red, Green > ground. and it works fine in the bathroom. all my wires from my wall were black so i made sure to put the ground wire to the side.

Then there would be another problem. Overheating wires. Could be dangerous. But the effects of a loose connection would be flickering lights that are plugged into the outlets or intermittent contact.!

The motion detector didn't have a neutral?
Check for neutral connection in the switch box that has come loose.
In your first post you said you swapped out the outlets. Now you are saying you only changed the switch. Which is it? You have a loose or open connection somewhere.

Is that green connected to a black wire? It should be connected to the bare wires. The black wire is the power to the receptacles and should be connected one of the other black wires.
On the original switch, two of the blacks must have been connected to the same screw. One of those black is power in and the other is power to the dead receptacles.
