FMC vs AC/BX
Can someone tell me if there is a difference in terms of code between Flexible Metal Conduit and Armoured Cable? I've got a very short run (about 2') of AC and I like the idea of an FMC rather than AC as it'll be easier to cut. It's just a run of 14\2.
Thanks!
Thanks!

No differences for code, just different wiring methods with different rules to follow. If you want to use FMC, go ahead. While code does not require it for a 2' run, I would recommend pulling in a ground wire.

Just looking for a simple way to guard the NM. I need to do a short run from a box to and external transformer. Transformer can't be covered, but AC needs to be protected. Easier to use the NM I already have.

It's not outside at all. It's a run from a wall box to an LED transformer/rectifier. It's on top of my cabinets. 120ac comes up from the basement to a wall switch. Switched 120ac up to above the cabinets where a transformer exists. Then the 12vdc back down to the leds undercabinet.

One place is 84" and the other is probably 90" (we have 9' ceilings).
And I did email the city inspector to see what he would consider "subject to damage" since he's the one that ultimately signs the paper :-)

It is pretty common to poke some Romex out of the drywall on top of the cabinets to power the light transformer. I don't expect there to be any problem from the inspector on this one.

really? And I could get away without a junction box up there too then? Wouldn't I need some sort of strain relief to make sure the Romex doesn't get yanked or anything?

Yeah this transformer has knock outs so that's covered with no problem. Still haven't heard back from the inspector. Maybe just have to call.
