I am running a new circuit from the electric breaker box to a new light fixture. My house was built in 1927, but has updated wiring using armoured cable, even inside the walls. Is it ok for me to use NML (sheathed electrical cable) cable for the new run. NOTE. The ceiling height in the basement is around 7ft, could this be the reason for armoured cable everywhere?

Since nobody else has replied, I'll take a stab at it. I can't think of any reason why sheathed electrical cable would be unacceptable. Also, don't know why armored cable was used before.

Hi winneymj,
I believe that older armoured cable used two wires (black/white)and the armour was the ground.So long as you ground your sheathed electrical cable you're all set.

Hi winneymj,

I'm not clear if you're running the wire just along the ceiling, up a wall, or both. In any event though, be SURE you install the wire properly. Depending on the route you're taking and so on, there are 'protections' that should be incorporated into the project. For example, if you're running wire that needs to pass 'through' a notch in a joist or stud, it needs to have a metal 'cover' to protect it from being nailed into when the wood is covered. (I'm not sure what it's called but it has to be done.)

Consider buying yourself a GOOD DIY Electrical Book. Review the ones from Reader's Digest and Time/Life if you can. If you're doing a lot of renovating vs. new construction, see to it that the book you buy concentrates in renovation more than new construction, vs. the other way around. (Or just get both books.) You'll be spending saved money on a GOOD book.

My best to ya and hope this helps.
