distinguish electrical equipment from
the structure to which it's attached.
Electrical equipment, such as electric
signs, is certified by a qualified electrical testing laboratory (QETL) and
therefore does not require inspection
of its factory-installed wiring at the
time of installation by the AHJ (90.7).
The structural element of the installation is not included in the listing of
the electrical equipment, and this
aspect is subject to local rules effective in the jurisdiction where the
Other significant new additions
to Article 600 include field marking
requirements. Signs that have been
retrofitted with LEDs will require
permanent markings denoting that
the original illumination system has
been changed, along with the kit
manufacturer and installer's identifier
Signs with remote disconnect
switches that are not within sight of a
sign will require a marking identifying
the location of the disconnecting
SIGNS OF THE TIMES
What was your contribution to this
iteration of the NEC?
During the 2017 NEC cycle, I worked
on and submitted 17 Public Inputs
and eight Public Comments on behalf
of ISA's Electrical Code and Standards
Subcommittee. As such, I drafted the
input and compiled the necessary substantiation. This was a collaborative
effort with contributions by Randy
Wright of the United States Sign Council, especially with regard to creating
the new tables for Class 2 cable.
In terms of debate, or complex
issues, how would you rate this
year's discussion, compared to
In every NEC cycle, some input for
new proposals results in disagreements and intense debate among
industry participants. During the
2017 cycle, compiling the new application table for Class 2 Cable in 600.33
drew the most discussion, and this
wasn't resolved until after a Notice of
Intent to Make a Motion and a subsequent Certified Amending Motion
(CAM 70-21) had been resolved. This
entailed making further modifications
to the table as previously accepted
by the Code Making Panel (CMP) 18
for publication in the 2017 NEC.
Were there any significant procedural changes this year with
regard to making changes?
Yes. The formal code-making procedure, which had been in place for multiple decades, was revised. The former
"Proposal" period was changed to
"Input Stage" and the former Report on
Proposals (ROP) was discontinued
and renamed "First Draft Report." The
"Comment Stage" followed, but the formal Report on Comments (ROC) was
discontinued. Additionally, activities
on CMP 18 could be viewed in real time
digitally on NFPA's Terra View website.
How many "sign representatives"
were involved in this year's changes?
