What does the 2014 code say about number of wires run through a bored hole? Can I run 2 Romex 12-2 cables through a 3/4in or 1in hole? I need to add outlets to my unfinished basement (probably 8 total) and I need to run a new circuit from panel. Can I save myself some time and hassle by running my new wire through a current hole w/1 existing wire?

  • The linked answer nails it and why. complicated math, and what falls out the bottom is four circuits. Unless they're 3-phase, in which case three. It's the same math as wires-per-conduit. – Harper - Reinstate Monica Jan 23 '17 at 18:21
