Is a light fixture a piece of equipment?
As defined by Article 100 of the NEC
Equipment. A general term, including material, fittings, devices, appliances, luminaires, apparatus, machinery, and the like used as a part of, or in connection with, an electrical installation.
What does section 314.16 have to say about the strap that a light fixture is mounted to?
314.16(B) (4) Device or Equipment Fill. For each yoke or strap containing one or more devices or equipment, a double volume allowance in accordance with Table 314.16(B) shall be made for each yoke or strap based on the largest conductor connected to a device(s) or equipment supported by that yoke or strap. A device or utilization equipment wider than a single 50 mm (2 in.) device box as described in Table 314.16(A) shall have double volume allowances provided for each gang required for mounting.
Reading the text outlined in red I am left under the impression that the strap counts as something.
What does 314.16 have to say about clamps?
314.16(B) (2) Clamp Fill. Where one or more internal cable clamps, whether factory or field supplied, are present in the box, a single volume allowance in accordance with Table 314.16(B) shall be made based on the largest conductor present in the box. No allowance shall be required for a cable connector with its clamping mechanism outside the box.
It is easy to see that the clamping mechanism is on the inside of the box.
Would Scott?s installation be code compliant?
It is easy to see that the clamping mechanism is on the inside of the box.
There is a strap installed to mount a piece of electrical equipment from.
I say that there is a code violation.
George,
Thanks as I needed a good laugh this morning.
