Marne and Associates NESC and OSHA Newsletter addresses issues relevant to power and communication utilities.
In This Issue:
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).
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.
