Motors and Conductors

Join us for our seminar this Saturday, June 6, at the Desert Pines Golf course. The seminar will consist of half a day of instruction on motors and half a day of instruction on conductors. Since the Las Vegas Valley area is currently operating under the 2011 NEC, the classes will be based on this version.

Equipment Temperature Ratings

Although much of the available wire and cable is rated 90C, and many connectors are rated at 90C, equipment such as panelboards, switchboards and similar equipment is typically limited to 75C. For example, UL 67 has provisions for testing with 60C and 75C wire, but not 90C wire. Allowable conductor ampacity should be based on the “weakest link” temperature – which is often that of the equipment where it terminates. If you are using wire or cable with a 90C temperature rating, the corresponding ampacity may be used for temperature correction or adjustment, but the final ampacity must not exceed that found in the temperature column corresponding to the marking on the equipment.

Flexible Cords Above Ceilings

Routers, projectors, signs, etc. are frequently installed on or near ceilings. Building owners often request that the equipment cords be run through the ceiling for aesthetic reasons, in order to conceal the extra cord and the connection. Unfortunately, this is a violation of the NEC. If we look in 400.8, we find the Uses Not Permitted for Flexible Cords and Cables. List item (2) tells us that flexible cords and cables shall not be used “Where run through holes in walls, structural ceilings, suspended ceilings, dropped ceilings, or floors.” 
Some of the concerns with running flexible cords and cables through ceilings include damaging the cord due to abrasion against the ceiling materials, concealing damage to the cord or connection, the plug being partially pulled out of the receptacle resulting in a poor connection, etc. Additionally, the space above a suspended ceiling may be considered a plenum, and any wiring method in that space must comply with 300.22(C). There are options available to make an aesthetically-pleasing and code-compliant installation, so do your homework and find a solution that meets the needs of the customer and the requirements of the NEC.
