Since my first post on NFPA79 in relation to sensor cables was published, there have been more and more customers asking me for a statement of compliance. So after much review, we decided to ask the professionals. As a member of the NFPA you can call and talk to a document specialist to help you clarify the wording and how it applies to your exact situation.
During my conversations with them, I learned that a new revision of NFPA79 that will be released in 2011. This version I hope will help clarify the concerns people have with the original wording “126.96.36.199 Single conductor or multi-conductor Type AWM shall not be permitted.” Most, if not all, sensor cables are built-in the Type AWM.
