Receptacle.

A contact device installed at the outlet for the connection of an attachment plug, or for the directconnection of electrical utilization equipment designed to mate with the corresponding contactdevice. A single receptacle is a single contact device with no other contact device on the sameyoke. A multiple receptacle is two or more contact devices on the same yoke. (CMP-18)

Informational Note: A duplex receptacle is an example of a multiple receptacle that has tworeceptacles on the same yoke.

Where control conductors are spliced, terminated, or connected in the same luminaire orenclosure as the branch-circuit conductors, the control conductor shall not be of a color reservedfor the grounded branch-circuit conductor or the equipment grounding conductor.

CommitteeStatement:

The panel has created a new section 410.69 to prevent lighting control conductors frombeing installed using the same color as the branch circuit conductors. One common controlconductor scheme is to use "purple and gray" colored control conductors. 200.6(A)specifically permits white and gray to be used in the identification of grounded conductors. Ashock incident could occur when "gray control" conductors are inadvertently spliced to thegrounded conductor. The panel concludes that wire colors reserved for grounded branchcircuit conductor or equipment grounding conductor should not be used for controlconductors. Ungrounded conductors can be any color.

(C) Installation in Fire-Resistant Construction.

Luminaires marked “FOR USE IN NON-FIRE-RATED INSTALLATIONS” shall not be used infire-rated installations. Where a luminaire is recessed in fire-resistant material in a building offire-resistant construction, a temperature higher than 90°C (194°F) but not higher than 150°C(302°F) shall be considered acceptable if the luminaire is plainly marked for that service. therecessed luminaire shall satisfy one of the following:

(1) The recessed luminaire shall be listed for use in a fire resistance–rated construction.

(2) The recessed luminaire shall be installed in or used with a luminaire enclosure that is listedfor use in a fire resistance–rated construction.

(3) The recessed luminaire shall be listed and shall be installed in accordance with a tested fireresistance–rated assembly. When a tested fire resistance–rated assembly allows theinstallation of a recessed fluorescent luminaire, a recessed LED luminaire of comparableconstruction shall be permitted.

CommitteeStatement:

The existing code text of 410.115(B) with only temperature requirements and with no meansof verification is insufficient. Testing that includes all the applicable considerations andsubsequent listing of a fire resistance rated assembly and luminaire by an NRTL takes awaythe guesswork for the installer, contractor, and electrical inspector in the field. The panel hasrevised the requirements for installation in Fire-Resistance Construction to be consistent withcurrent listing options and relocated the requirement to section 410.116 since it no longerreferences temperature requirements. The panel additionally updated the requirement withprovisions that address the use of LED luminaires.

CommitteeStatement:

This section was originally added to allow transformer boxes (enclosures) used to housetransformers to include primary and secondary conductors. The first word implied to someAHJs and installers that the sign body was an enclosure by default, which is not correctunless the sign is marked to require the use of a recognized component sign face. The signbody should not include these high voltage conductors. Removing the word signs will clarifythe intent of this section for transformer boxes and should eliminate the confusion.

This revision adds clarity to the requirement for the disconnecting means to ensure allconductors inside the box are de-energized prior to servicing.

Article 406 does not address single pole separable connectors nor does it require a single pole separableconnector to be listed. Single-pole separable connectors are widely available in the market place and areused in a variety of applications, including land transportation, non-hazardous refinery and miningoperations. The nationally recognized product standard for single pole separable connectors, ANSI/UL1691 contains requirements that correspond to the required construction as well as the performance andmarking requirements to evaluate the suitability of a single pole separable connector. Requiring the use ofa listed single pole separable connector will confirm that the installed device complies with the requiredcharacteristics of 406.13. Sections 520.53(C) and 530.22 are the source of these requirements.

Article 406 contains requirements for a variety of different types of plugs and receptacles such asreceptacle with USB charger, tamper resistant receptacles and weather-resistant receptacles. However,the Article does not address single pole separable connectors, which are widely available in the marketplace.

(C) Wired Luminaire Sections.

Wired luminaire sections are paired, with a ballast(s) or LED driver(s) supplying a lamp lightsource or lamps light sources in both. For interconnection between paired units, it shall bepermissible to use metric designator 12 (trade size 3⁄8) flexible metal conduit in lengths notexceeding 7.5 m (25 ft), in conformance with Article 348. Luminaire wire operating at line voltage,supplying only the ballast(s) or LED driver(s) of one of the paired luminaires, shall be permitted inthe same raceway as the lamp light source supply wires of the paired luminaires where thevoltage rating of the light source supply wires is greater than the line voltage .

CommitteeStatement:

With the increasing numbers of indoor plant growing facilities being established, horticultural lightingequipment providing a wavelength(s) of light necessary for plant growth has become a rapidly expandingtechnology. While the Code has provisions for agricultural buildings in Article 547, the newer indoorhorticultural lighting installations demand different considerations. For example, since horticultural lightingequipment needs to be adjustable to accommodate seasonal plant diversity and growth, flexibleconnection to branch circuits and between luminaires is provided. Also, horticultural lighting equipment istypically installed in close proximity to each other, and can have unique support from structures in theenvironment.

Code requirements are needed to ensure safe installations and to facilitate inspection; therefore, thepanel has created new Part XVI for Horticultural Lighting Equipment.

(B) Marking.

A disconnecting means for a sign, outline lighting system, or controller shall be marked with theidentity of the sign, outline lighting system, or controller it controls.

Exception: An external disconnecting means that is mounted on the sign body, signenclosure, sign pole, or controller shall not be required to identify the sign or outline lightingsystem it controls.

CommitteeStatement:

External disconnecting means in a remote location from the sign, outline lighting system, orcontroller might not be readily associated with the sign, outline lighting system, or controllerthey control. Anecdotal evidence points to situations where a disconnect technically withinsight of the sign (that is, not exceeding 50 feet and visible to the service technician) wouldnot be recognized or identified as controlling the sign, outline lighting system, or controller byanyone other than the service technician.

Sign service and maintenance personnel, as well as first responders, have a need to knowwhat utilization equipment the disconnect(s) is designated for where it is not mounted on thesign, outline lighting system, or controller.
