I know in a basement you can not run RX under the joists, but if there is a drop ceiling, I believe it is allowed, but can't find the code to back it.
Article 334.10 or 334.12 maybe?
I know it's lame.... but... can you post those two sections for me....
I would say 334.12 (A)(2) allows this. Agreed?
In kind of a back-handed way....... 334.12 is Uses NOT Permitted.
I wouldn't--yet that's just me looking out for the next person who decides to remove the drop ceilingagreed.. what are your thoughts?

Personally, I've never felt all warm and fuzzy about sticking NM to the bottom of the joists just because a drop ceiling is going up. I'd rather have it all up above the bottom of the joists (drilled through) so 4 months from now, when the owners get tired of the 60's look in their basement, it's ready for drywall.
I approached it differently:
334.15 Exposed Work.
(C) In Unfinished Basements and Crawl Spaces. Where cable is run at angles with joists in unfinished basements and crawl spaces, it shall be permissible to secure cables not smaller than two 6 AWG or three 8 AWG conductors directly to the lower edges of the joists. Smaller cables shall be run either through bored holes in joists or on running boards. NM cable installed on the wall of an unfinished basement shall be permitted to be installed in a listed conduit or tubing or shall be protected in accordance with 300.4. Conduit or tubing shall be provided with a suitable insulating bushing or adapter at the point the cable enters the raceway. The NM cable sheath shall extend through the conduit or tubing and into the outlet or device box not less than 6 mm (? in.). The cable shall be secured within 300 mm (12 in.) of the point where the cable enters the conduit or tubing. Metal conduit, tubing, and metal outlet boxes shall be connected to an equipment grounding conductor.
In 99.9% of the situations I've seen if there is a suspended ceiling it's not an "undfinished basement"
i would never suggest drywallin the ceiling in a b-ment, IMO
edit to add: unless it was framed down to create a chase, but still....
I could care less what the HO wants to do. Drop ceiling... drywall... cover it with dylithium crystals for all I care. I just drill the joists and 'git-er-done'.
...... they gotta pay for it.
All that requires is strapping, which is 1x's attached perpendicularly to the joists.Personally, I've never felt all warm and fuzzy about sticking NM to the bottom of the joists just because a drop ceiling is going up.

In this case....Exactly!!!I could care less what the HO wants to do. Drop ceiling... drywall... cover it with dylithium crystals for all I care. I just drill the joists and 'git-er-done'.
i've been in some old houses that don't even have a drop ceiling and the rx is crossin the joists
but i do understand your point, lookin for NEC requir. though
