Signs of the Times - August 2017 - 45

NEC IMPLEMENTATION BY STATE

subject to the same NEC requirements as all other electric signs. 

ISA Alternate and Randy Wright,
RKW Consulting. Paul Yesbeck (ACU
Sign Corp.) was the National Electrical
Contractors Association (NECA)
Alternate but, because of NECA
policy, did not participate during
the industry Input Stage. CMP 18
Chairman Bobby Gray, the principal
for NECA, appointed Randy Wright
to chair a task group for Article 600
input which was divided into three
committees. Lee Hewitt (UL), Jack
Jamison Jr. (IAEI) and Paul Costello

(NECA and IBEW) represented Committee 1. Committee 2 included Rick
Hollander (IAEI), Donald Berlin (Intermatic) and Chuck Kurten (UL). Populating Committee 3 were Wes Wilkins,
ISA Principal, Bill Dundas, ISA Alternate, and Paul Yesbeck, NECA. 
To what extent has dynamic
digital signage impacted the
2017 NEC?
Digital signs are considered electrical utilization equipment and are

To what extent were there any
changes with regard to LEDs, fluorescent lighting and/or neon?
The rules in 600.33 previously were
specific to LED sign illumination
systems. This has been amended
to apply to all Class 2 illumination
systems rather than being limited
exclusively to LEDs. This change
harmonizes with the secondary
wiring requirements in 600.33 and
Table 600.33(A)(1)(2) for power-limited
cable applications.
 
What are the sections of the NEC
that impact signage?
In addition to the principal Article 600,
Electric Signs and Outline Lighting,
Chapters 1-4 of the NEC apply generally to all electrical installations.
Chapter 6, Article 600 supplements
or modifies Chapters 1-7 [e.g., 250.3
which mandates grounding and bonding for electric signs is modified by
600.7(B)(1) Exception: Remote metal
parts of a section sign or outline lighting system only supplied by a Class 2
power supply shall not be required to
be bonded to an equipment bonding
conductor].
The NEC regulations for safe use of
electricity are national in scope; however, each jurisdiction has the prerogative to amend and interpret the
NEC. Knowledge of the NEC and local
rules in the jurisdiction are essential
because the authority having jurisdiction at the installation location has
the final say in the approval process.
So, stay active with your local sign
association, whose job it is to help you
stay abreast of these issues. However,
the vast majority of AHJs do conform
to the NFPA and IAEI interpretation
of the NEC. Paying attention to these
technical changes now will help prevent any unpleasant surprises as they
trickle down to a locality near you.
