ECN Forum Forums General Topics of the Trade General Discussion Area How would you do it

I'm going to remember that motion detector idea. But the ceiling could be concrete to.
Just tell her she has to live with the emt. Just do a real nice neat job.

Greg,
Cut in a masonary box and purchase a 6' flexible bit(DiversaBit), dirll up from switch box location. Proceed with M/C cable fished down the wall. The bit should have holes in it to use as a fish. Yes I have done this before. It isn't easy but thats why I charge more and still get the job lol

Ob, I don't think we are drilling through 16" of concrete

16" concrete header vs: DiversaBit masonry....odds on favorite would be the header IMHO

You also have a better than fair chance of hitting one of the 4 #5 rebars in the tie beam.

I would consider using some sort of low voltage control method (for example the same sort of power limited supply and relay used with some motion sensor systems), combined with suitable 'flat' conductors simply stuck to the wall and painted the same color as the wall.

This is done now with no wall switch, just the motion detector. Once they get power in there they might go for something else.
