Question:
Hello Charlie, I enjoy reading the CQD for my daily dose of code every morning. Can “smurf tubing” ENT be used to provide protection of NM Cable? Regards, Tim Jones
A
Answer:
Hi Tim, Electric Nonmetallic Tubing ENT, would not be permitted for the protection of NM Cable. Section 334.15 provides guidance on protecting exposed NM Cable. Specifically, Section 334.15(B) lists the wiring methods permitted for NM Cable protection and ENT is not on the list. Additionally, Section 362.12(8) prohibits the use of ENT where subject to physical damage.
