Servine at the Intl. Sign Assn.'s (ISA)
Sign Expo in Las Vegas, where he
helped present a seminar on the new
NEC. In his 55 years in the electricsign industry, Servine has served for
decades as a member of Underwriters
Standards Technical Panels UL 48, 879
and 879A, as an associate member of
the Intl. Assn. of Electrical Inspectors,
and as a member of ISA's Electrical
Subcommittee. He was honored last
year with the sign industry's highest

honor - the Kirk L. Brimley Distinguished Service Award - and filled
us in on the latest NEC updates and
revisions.
When was the 2017 NEC finalized?
The 2017 edition of the NEC was
issued by the NFPA Standards Council
August 4 with an effective date of
August 24, 2016. In turn, each state
ratifies the NEC with local amendments before it's enforced. You can

What are the most significant
changes since the 2014 NEC?
Three additions are significant - two
in Article 600 and one in Article 100
Definitions:
1) Class 2 cable applications for LEDs
are relocated from Article 725.154
to new tables in Article 600, which
pertain to electric signs [600.33(A)(1),
600.33(A)(2)]. This change addresses
the fact that references to Table 725.154
and Substitution Table 725.154(A)
in 600.33 of the 2014 NEC do not
provide a clear path for electric-sign
manufacturers, Nationally Recognized
Testing Laboratories (NRTLs) or the
Authority Having Jurisdiction (AHJ)
to determine the appropriate Class 2
sign cable application for the specific
installation location environment. 
This was the genesis of the new
Table 600.33(A)(1). Listed, powerlimited cable types germane to the
installation location environment of
Class 2 power-limited sign circuits
were extracted from 725.135 and
Table 725.154, Table 725.154(A) and
UL's White Book category: PowerLimited Circuit Cable (QPTZ). This
was submitted as Public Input No.
3600 and accepted by CMP 18 with
certain changes and additions. This
change eliminates the necessity of
searching for Class 2 cable applications outside of Article 600, which in
previous editions of the NEC lacked
a readily identifiable reference for
electric signs.  
2) A new Article 600.34 that
applies to Photovoltaic Powered
Signs has been added.
3) The definition of "structure"
has been changed in Article 100 to
