[GreenKeys] Electrical Cords and Storage RReels

[Peter Gottlieb]

Yes, but "current carrying conductors."  That's why even violations seldom cause fires. The NEC tries to keep you out of trouble; many strange sounding requirements came out of fire and incident investigations. 

I've heard many EEs tell me they don't need an electrician because they know everything already. After a few questions the truth comes out. 

If you want to (and it is legal) to do your own electrical work, I strongly recommend picking up the latest NEC book and follow ALL relevant sections and paragraphs, no shortcuts, no excuses.

If you read the Electrical Code you will note that if you put more than a certain number of wires in a conduit you have to derate their current carrying ability.  In the same way if you bundle standard NM type house wiring for more than a certain length you have to derate it also.  This is a heat issue.
