NESC® and OSHA Newsletter August 26, 2009

Marne and Associates NESC and OSHA Newsletter addresses issues relevant to power and communication utilities.

In This Issue:


Question #1:

Is there a reference in the NESC® that crossarms need to be on the same or alternating sides along a pole line?

There is not an NESC Rule that requires crossarms to be on the same side or alternating sides along a pole line. It is industry practice to alternate crossarm positions along a pole line for maximum strength of the line. This topic is discussed in McGraw-Hill's Lineman's and Cableman's Handbook (11th Edition). There are illustrations in this Handbook showing crossarm positions for straight pole lines, curved pole lines, and angled pole lines.

If you do not have a copy of the Lineman's and Cableman's Handbook, you can order one on our website. Click here.


Question #2:

How soon will there be a seminar covering the changes to the NESC® Codebook?

Currently change proposals for the 2012 NESC® are being published to gather industry comments. These comments will be reviewed by the NESC committee members prior to the final NESC change proposal voting. We will be discussing some of the change proposals in our upcoming newsletters. We will not be offering a seminar of the NESC changes until the 2012 NESC®  is published.
