With the 2017 release of the NEC coming soon, there are some changes and revisions you will need to know. To prepare you for the upcoming changes, TPC Training Systems introduces some of the proposed and expected changes to come with this release.
National Electrical Code2017 NEC
REVISION: 840.48 - Unlisted Wires and Cables Entering Buildings for Premises-Powered Broadband Communications Systems
In order to expand the coverage of Article 840, there is a proposal to recognize both twisted pair and coaxial cable-based systems in addition to optical fiber-based systems.
Proposed New Articles2017 NEC
Article 712 - Direct-Current Microgrids
The current state of energy storage technology, which includes batteries, and the anticipated evolution of energy storage, support the need for a singular set of requirements in the NEC covering such systems.
Article 706 - Energy Storage Systems
The current state of energy storage technology, which includes batteries, and the anticipated evolution of energy storage, support the need for a singular set of requirements in the NEC covering such systems.
Article 691 - Large-Scale Photovoltaic (PV) Electric Supply Stations
1) elimination of AHJ professional risk when assessing compliance of large-scale PV electric supply stations
2) enabling system engineers to use engineering best practices in the design of large-scale PV electric supply stations.

Proposed New Articles2017 NEC
Chapter ONE - General Requirements
2017 NEC
These working space signs would be required to meet the requirements of 110.21(B) for field-applied hazard markings and would need to read as follows:
NEW: 110.26(A)(4) - Working Space About Electrical Equipment - Clear Space Signs
“NOTICE - ELECTRICAL EQUIPMENT WORKING SPACE AND EGRESS AREA - NO OBSTRUCTION OR STORAGE ALLOWED.”
NEW: 110.26(A)(4) - Working Space About Electrical Equipment -Limited AccessAddresses equipment “located in a space with limited access,” such as above a suspended ceiling or in a crawl space.
There are four restrictions: Where equipment is located above a lay-in ceiling Width of the limited access working space Doors or hinged panels being capable of opening a minimum of 90° Space in front of the enclosure
NEW: 110.21(A)(2) - Equipment Marking - Reconditioned EquipmentRequires reconditioned equipment to be makred with the name, trademwark, or other descriptive marking, identifying the organization responsible for reconditioning the electrical equipment. It also requires the date of the reconditioning to be provided as well.
NEW: 110.16(B) - Arc-Flash Hazard Warning - Service EquipmentRequires additional information to be included in the arc-flash hazard warning label specifically addressing service equipment.
And at least one of the following: Available incident energy & corresponding working distance Minimum Arc Rating of Clothing Site-Specific Level of PPE
Nominal System Voltage Arc-Flash Boundaries
Requires Labels to Contain:
NEW: 110.14(D) - Electrical Equipment: Tightening Torque
Findings of a field study presented in 2011, indicated that installers incorrectly tighten electrical terminations at least 75% of the time when not using a torque wrench.
This proposed requirement would make it clear to installers and inspectors that using torque tools is required when a torque value is indicated on electrical equipment, such as a banelboard lug.

Chapter TWO - Wiring and Protection
2017 NEC
NEW: 250.52(B)(3) - Not Permitted For Use As Grounding ElectrodesDecisive language was proposed that would prohibit the structures and/or structural reinforcing steel of an in-ground swimming pool described at 680.26(B)(1) and (B)(2) from being used as a grounding electrode for a building or structure.
3.0m (10ft)or more
REVISION: 250.52(A)(2) - Grounding Electrodes - Metal In-Ground Support Structure(s)
Currently, two conditions exist in the 2014 NEC in order for a metal frame of a building or structure to qualify as a grounding electrode. The proposed text for the 2017 NEC leaves only one condition:
One or more metal in-ground support structure(s) in direct contact with the earth vertically for 3.0m (10ft) or more, with or without concrete encasement.
REVISION: 250.30(A)(4) - Grounding Separately Derived AC Systems - Grounding Electrode System
The new proposed text at 250.30(A)(4) will allow any of the building or structure grounding electrodes described at 250.52(A) to be used as the grounding electrode for the separately derived system without an order of preference.
NEW: 240.67 - Arc Energy Reduction (Fuses)The proposed requirements of 240.67 are based upon the requirements in 240.87 for circuit breakers, but modified to work with fusible switches. This arc energy reduction requirement for fusible switches has a proposed future effective date of January 1, 2020.
REVISION: 230.29 - Overhead Service Conductors - Supports Over BuildingsRevisions to 230.29 will require metal support racks or structures to be bonded by means of a bonding jumper and listed connector to the grounded overhead service conductor for grounded systems.
This proposed language will provide installers clear bonding provisions and the AHJ a clear requirement for enforcement.
NEW: 210.71 - Meeting Room ReceptaclesNew requirements for a minimum number of nonlocking-type 125-volt, 15-and 20-ampere receptacles to be installed in nondwelling unit meeting rooms have been proposed.
This proposal addresses the inherent concerns relating to inadequate access to electrial power in meeting rooms.
REVISION: 210.12(A) - Whole-House AFCI ProtectionThe proposed revision to 210.12(A) would require arc-fault circuit-interrupter (AFCI) protection for all 120-volt, single-phase, 15- and 20-ampere branch circuits supplying outlets or devices installed in dwelling units.
NEW: 210.11(C)(4) - Dwelling Units - Garage Branch CircuitsA new requirement has been proposed to require at least one 20-ampere rated branch circuit to supply dwelling unit garage 125-volt receptable outlet(s).
Many appliances and tools used in dwelling unit garages are rated at 12-16-amperes or higher and demand at least a 20-ampere rated branch circuit.
NEW: 210.8(B)(2)(A) - SPGFCI ProtectionThe requirements in this section have been expanded to recognize the fact that shock hazards are not limited to 15- and 20-ampere, 125-volt circuits at nondwelling unit locations.
REVISION: 210.8(A) - GFCI Protection: Dwelling Units
All 250-volt, single-phase, 15-and 20-ampere receptables installed in the locations specificed in 210.8(A), present a shock hazard and should be included in the GFCI protection in dwelling units.
