Expansion Unfortunately Driven by Deaths
• A 10-year-old girl was looking for some baby kittens
behind the family’s dryer when she was electrocuted.
Her father noted that when he tried to move the dryer
he too was shocked, but his adrenaline and panic
helped him get to his little girl who had unfortunately
already passed.

15
210.8(A)(5) Basements
• GFCI for dwelling units was expanded for all basements.
• In recent editions of the NEC we focused on un-finished
areas of the basement.
• When a home is equipped with a basement, this location
presents unique hazards to the occupants.
o Moisture, conductive surfaces - when a problem occurs that would
expose someone to electricity we must ensure protection is provided.

NEC 2020 Change
General Overview:
Changes to align with Article 422 which
focuses on appliances.
Substantiation Overview:
GFCI protection for specific appliances is
governed by Article 422. This language
helps ensure GFCI protection is a part of
the premise wiring when it may not be
provided as part of the appliance.

20
422.5 GFCI Protection for Personnel
• 422.5(A) General.
• Appliances identified in 422.5(A)(1) through (A)(7) rated 150 volts or
less to ground and 60 amperes or less, single- or 3-phase, shall be
provided with Class A GFCI protection for personnel. Multiple Class
A GFCI protective devices shall be permitted but shall not be
required.
• (6) Sump pumps
• (7) Dishwashers

210.8(E) Equipment Requiring Servicing
(E) Equipment Requiring Servicing.
GFCI protection shall be provided for the receptacles
required by 210.63.

22
210.8(E) Equipment Requiring Servicing
(E) Equipment Requiring Servicing.
GFCI protection shall be provided for the receptacles
required by 210.63.
NEC 2020 Change
General Overview: GFCI is now required for those receptacles installed as required in
210.63 for those who service equipment such as HVAC and more.
Substantiation Overview: The code panel recognized that some equipment may not be
located in areas where GFCI is already required but is important for safety of the worker.

23

24
The receptacle installed
to serve HVAC
equipment in the attic is
in an area where GFCI is
not required. (As long as
the AHJ does not classify
this area as a crawl
space) This NEC 2020
change will ensure this is
a GFCI receptacle.

25
210.8(F) Outdoor Outlets
(F) Outdoor Outlets.
All outdoor outlets for dwellings, other than those covered
in 210.8(A)(3), Exception to (3), that are supplied by
single-phase branch circuits rated 150 volts to ground or
less, 50 amperes or less, shall have ground-fault circuit-
interrupter protection for personnel.
Exception: Ground-fault circuit-interrupter protection shall not be required
on lighting outlets other than those covered in 210.8(C).

26
This is considered and outdoor outlet.
Most GFCI requirements are around
“Receptacle outlets”. NEC 2020
created new requirement to address
outdoor “outlets”

27
Outdoor Outlet GFCI Expansion Driven by Deaths
This change was driven
by the death of a child
who jumped over the
fence in this picture and
due to a wiring issue in
this condenser was
electrocuted by
touching the fence and
the condenser.

Article 230 Services
230.62 Service Equipment – Enclosed or
Guarded

29
230.62 Service Equipment – Enclosed or Guarded
• Barriers provide a
means to protect the
electrical worker from
contact

30
Line-Side Barriers
(C) Barriers. Barriers shall be placed in service equipment such
that no uninsulated, ungrounded service busbar or service terminal
is exposed to inadvertent contact by persons or maintenance
equipment while servicing load terminations.
Exception: This requirement shall not apply to service panelboards
with provisions for more than one service disconnect within a single
enclosure as permitted in 408.36, Exceptions 1, 2, and 3.

31
Line-Side Barriers
This requirement impacts all service equipment. Barrier requirements previously
only resided in 408.3(A)(2) impacting service panelboards, switchboards and
switchgear. NEC 2020 expanded this barrier requirement.

32
Line-side barriers
This exception now removed was introduced in NEC 2017 and one of the
changes that raised the awareness of the hazards associated with having 6
disconnects in the same panelboard resulting in NEC 2020 impacting the 6-
disconnect rule.

33
Line-Side Barriers
408.3 changes in NEC 2017 are about reducing
the incidents of electric shock in an exposed area
of service entrance equipment – Line side
terminals of the main OCPD

34
Exposure to Hazard – Energized Components
Turning off the main OCPD
de-energizes what is
downstream. Service
entrance conductors and
terminations are still
energized
Service Entrance Conductors
Branch OCPDs

35
Exposure to Hazard – Energized Components
• The residential
panelboard is an easy
solution to understand
the hazard
De-energized by Main

36
Line side barrier
provides protection from
inadvertent contact.

37
230.67 Surge Protection

38
Surge Protective Devices (SPDs)
New Article 242 – Overvoltage Protection:
• Surge now has a focused article setting the stage for future
work.
• The new article does not add new requirements, but rather
consolidates surge requirements from around the NEC.
• This effort will bring future attention around performance
requirements that align with their location in the circuit.

39
230.67 Surge Protection
(A) Surge-Protective Device.
All services in supplying dwelling units shall be provided with a surge-protective device (SPD).
(B) Location.
The surge protective device (SPD) shall be an integral part of the service equipment or shall be located
immediately adjacent thereto.
Exception: The surge protective device (SPD) shall not be required to be located in the service equipment as
required in (B) if located at each next level distribution equipment downstream toward the load.
(C) Type.
The surge protective device (SPD) shall be a Type 1 or Type 2 SPD.
(D) Replacement.
Where service equipment is replaced, all of the requirements of this section shall apply.

40
Types of Surge Protective Devices
• 4 Types:
o Type 1 – Permanently connected SPDs intended for installation between
the secondary of the service transformer and the line side of the service
disconnect overcurrent device
o Type 2 – Permanently connected SPDs intended for installation on the load
side of the service disconnect overcurrent device, including SPDs located
at branch panel.

• The 6-disconnect rule was modified as per 230.71 in
such a manner that a panelboard with 6 disconnects
within will no longer be permitted. Addresses
issues/concerns around 110.16, 240.87, 240.67,
and 408.3 requirements.
• Some exceptions were deleted because of this
change as well.

45
230.71 Maximum Number of Disconnects.
Each service shall have only one disconnecting means unless the requirements of 230.71(B) are
met.
(A) General.
For the purpose of this section, disconnecting means installed as part of listed equipment and
used solely for the following shall not be considered a service disconnecting means:

to the options in 230.71(B) which is where
NEC 2020 has introduced major changes

47
(B) Two to Six Service Disconnecting Means.
Two to six service disconnects shall be permitted for each
service permitted by 230.2, or for each set of service-entrance
conductors permitted by 230.40 Exception No. 1, 3, 4, or 5. The
two to six service disconnecting means shall be permitted to
consist of a combination of any of the following:

48
Two to six service disconnects shall be permitted for each
service permitted by 230.2, or for each set of service-entrance
conductors permitted by 230.40 Exception No. 1, 3, 4 or 5. The
two to six service disconnecting means shall be permitted to
consist of a combination of any of the following:
This is the “6-disconnect” rule that has been a part of the NEC for decades. This text was
modified to enable the section to introduce the new options for these installation locations

49
(1) Separate enclosures with a main service disconnecting means in each
enclosure
(2) Panelboards with a main service disconnecting means in each
panelboard enclosure
(3) Switchboard(s) where there is only one service disconnect in each
separate vertical section where there are barriers separating each vertical
section
(4) Service disconnects in switchgear or metering centers where each
disconnect is located in a separate compartment

General Overview:
Switchboard applications will change leveraging vertical sections separated by
barriers.

53
enclosure
section
General Overview:
This requirement addresses switchgear keeping the service disconnects in their
own separate compartments enabling barriers and reducing the likelihood of
shock.

54
Informational Note No. 1: Metering centers are addressed in UL 67, the
standard for panelboards.
Informational Note No. 2: Examples of separate enclosures with a main
service disconnecting means in each enclosure include but are not limited to
motor control centers, fused disconnects, circuit breaker enclosures and
transfer switches that are suitable for use as service equipment.

55
• New informational note to help the user of the NEC understand that metering centers fall
under the same standard as panelboards. This connection may not obvious to most but
could be important to installers and inspectors and specifiers.

56
This new informational note provides more guidance to the user of the NEC to understand
these new requirements.

57
Key Take-Aways
• The six-disconnect rule has changed in a manner to
increase safety for electrical workers
• The new changes make it possible to barrier the line
side unprotected terminations reducing likelihood of
shock
• 6-disconnects in a panelboard is no longer permitted as
part of these changes
