Mark your outlets

I find it hard to see where to insert the plugs on a black powerbar. I put painters tape around all 4 (four) sides of the plug holes and I painted the top of the plug, (being careful not to have any paint or nail polish go into the holes) with either craft white paint or a bright color of nail polish. Let it dry completely (use more than 1 (one) coating), remove the tape and now I can see where to place the plug into the correct holes easily. You can use scotch tape or painters tape. Be sure to fold over about 1/2" at 1 (one) end of the tape so the tape can be removed easily.
