Re: Bundled = Derated

Trevor you will make Ryan smile with that reference.

Thanks Bob. Prior to Ryan's post on the subject I had never even heard of it.

A panel may be used as a raceway, but can't be a raceway, IMO. An analogy would be, a car may be used as a toilet, but it is not a toilet, it is a car.

To tag a job because the electrician that cut in the panel using tye wraps for bundling is ridiculous.IMHO

Re: Bundled = Derated

Derating due to "bundling" is not considered when in a panel. What we refer to as loadcenters and panelboards are really made up of two seperate and independant things. Bus bar/mounting assemblies and enclosures.

408.38 says it very specifically - panelboards are mounted in cabinets/cut-out boxes. If you take the busbar out of the enclosure what you have left falls under 312, which is not one of the raceway articles.

310.15(B)(2)(a) only applies to raceways and cables, and not even to all raceways, see 366.23(A) and 376.22.

Now that is some real truth.

All of us seem to think electricity would stop flowing without our help.

Bob,

I know that electricity would keep flowing without me.... it would just spill out onto the floor though and make a big puddle.

Electron spills are always so hard to mop up.

No problem. Just use a positronic vacuum.
