BX Cable and tin ceiling


Is it OK to run bx cable atop a tin ceiling, i.e. is there a shock or short hazard? The cable runs along the bottom of the joists and there will be furring strips between the joists and the tin, but i would suspect that the cable will make contact with the tin somewhere.

As long as the BX is bonded it is legal. I do not really like the idea.

It is new AC 12/3 cable, so it has the bonding strip, and is terminated on each end of the cable with clamps at the j-boxes...is that what you mean?

Yes. As long the first box is bonded correctly you are fine.

If this wire is not being fished in an existing cavity, you need to follow some other rules.


The cable must be installed at least 1 1/4" inches from the face of any stud or furring strip.

Any holes holes must be drilled so are still meeting this requirement. If the hole results that cable is too close to the face, you must use nail plates to protect the cable.
