Code Question Of The Day

Charlie, 

I’ve been just reading the question of the day up until now. Here is my question. There is a new requirement to install a neutral at switch locations. The rule does not say one has to connect the neutral or use it. The issue is I can still purchase an occupancy sensor switch with a neutral pigtail and a switch that has only an equipment-grounding (green) conductor pigtail. Both are listed and available by more than one manufacturer. Is it a violation to install the switch without the neutral pigtail if both are listed and available when the NEC just requires the neutral to be installed in the switch location? Thanks for your time and wisdom.

Hi Charlie,

Great Code Forum here. My question is as follows: Are all junction and pull boxes required to be listed? Thanks in advance for your reply.

Thanks for the nice comments and participation in the CQD. All junction and pull boxes are not required to be listed as a general rule, but some boxes are required to be listed such as boxes for luminaires (weighing more than 50 lbs.), boxes for ceiling-suspended paddle fans, and floor boxes. Part III of Article 314 provides construction specifications for boxes, conduit bodies, and fittings. Sometimes custom pull and junction boxes are necessary for unique construction features. This allows field fabrication of custom boxes to meet the special sizing requirements and shapes.
