NESC® and OSHA Newsletter May 25, 2010
Marne and Associates NESC and OSHA Newsletter addresses issues relevant to power and communication utilities.
 
In This Issue:

2012 NESC Proposed Changes:
 
The 2012 NESC comment period is closed.
 
The change proposals for the 2012 NESC have been published to gather industry comments. The public comment period (for submitting public comments on the proposed changes) ended May 1, 2010 and is now closed.
 
In general, the next steps are another round of NESC committee meetings to review the public comments that were submitted, another round of NESC committee voting on the proposed NESC changes, and finally a new 2012 NESC document (to be published on August 1, 2011).


NESC Question:
 
Relative levels (position) of phone, CATV, and fiber.
 
Is there an NESC Rule that gives the order of the communication attachments on a distribution  power pole (for example, fiber on top, CATV in the middle, and phone on the bottom)?
 
Yes and no. NESC Rule 220A discusses standardization of levels by agreement of the utilities concerned but it does not provide specific locations. Many years ago, telephone was the main joint-use communications attachment on a distribution power pole. Then along came cable systems (CATV), these systems were typically installed above telephone. Today, pole owners are receiving numerous requests for attachments by fiber utilities. Occasionally the question gets asked, can a fiber utility be located underneath the telephone utility? As stated above, NESC Rule 220A applies and specifies agreement of the utilities concerned. Rule 235H (clearance between communication conductors) is also applicable and specifies, in some cases, agreement between the parties involved. The pole owner can certainly be an involved party or concerned utility. Once standardization of levels have been agreed upon, there are several other NESC Rules that must be met including but not limited to clearance issues and strength and loading issues.
