NFPA 79 for AWM Cables in 2011

Share

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.

Defining IP Ratings and NEMA Ratings

As I was preparing to write my blog entry, I was browsing my e-mail and came across an article in the October Issue of TIA Newsletter (Totally Integrated Automation) from Automation World, concerning IP Ratings.  I found the article , very informative as it broke down the different degrees of IP ratings, as well as some similarity and differences between IP ratings and NEMA ratings.  I only wish there was some information involving IP69K. 

This article, IP Ratings – What are they and what do they mean,  is a great starting point to learn about IP Ratings, I suggest you stop by and read it.
