Bookmark or Share- electrical - Can I run stripped Romex/NM through conduit? - Home ...It is permissible to run the entire, jacketed NM-B cable through the conduit. The restriction is that it takes a mighty bite out of conduit fill, because the NM-B cable must be treated the same as a round conductor of the wide dimension. This is particularly punishing when there are 2 "wires" (i.e. two NM-B cables) because 2 "wires" are allowed ...
- Can I use indoor Romex in buried outdoor conduit?UF cable is THHN conductors plus a ground encased completely in PVC. Romex is a brand name for non-metallic paper bonded cable (NM-B, as printed on the jacket) with a PVC jacket. This is why type UF is suitable for burying and wet locations (or dry) where NM-B cable is suitable only for very specific dry locations.
- electrical - Can Romex (NM-B) cable be run through conduit? - Home ...In addition to Tester101's excellent answer on when NM-B can be run through conduit, there is a section in the NEC which indirectly prohibits running NM-B through conduit in specific scenarios: From the 2014 NEC: 312.5 Cabinets, Cutout Boxes, and Meter Socket Enclosures.
- NM-B vs THHN amp capacity? - Home Improvement Stack ExchangeEven though the wires within NM-B cable are THHN wire and have insulation rated for 90 degrees C, many versions of the code, including 2011 NEC Section 334-80, limit ampacity of non-metalic cables such as NM-B to no more than that permitted with an insulation rated for 60 degrees C (probably due to heat retention by the thick outer PVC jacket ...
- electrical - THHN versus NM for conduit wiring? - Home Improvement ...I am wiring a small workshop, using conduit. I was shocked to see how expensive THHN/THHW cable is, with respect to NM-B: at local big-box store, 100ft of 14/2 NM was $33, whereas 100ft of THHN was about $20 (so $60, almost double the price of NM, for 2 conductors plus EGC). I am wondering about the pros and cons of using NM instead of THHN.
