When you say standard, do you mean not heavy duty, or hard & extra hard usage? We use them as power cords for starters on portable pumps in a Hazardous Location. Seals are required. I have also used them for temporary power on test bin agitator motors to conduct mixing studies in our research facility. Removed after the test, of course?

Redsy,

By standard, I mean that they are not made for a specific purpose. Or have inline GFCI protection.
I'm under the impression that the cords We use for our work are supposed to have GFCI protection somewhere, either in the circuit or inline.

What can you legally use the little lamp cord (zipcord) extensions for?

Yeah... my Mom's favorite was the percorlator cord... I wonder if there is something freudian going on here... We became electricians in the basic need to "control the wire"...

If the question refers to "flexible cords and cables", then Art. 400 would be the controlling NEC rules. Specifically, Art. 400-7 Uses permitted and 400-8 Uses Not Permitted. "Standard" extension cords are used in our homes to "extend" the receptacle power to a more convenient location for power usage, and on construction sites for the same reason. However, all are supposed to be temporary as sparky says "nothing permanent".

true, but then it get's to again be somewhat definitional as to what would be considered permanent.

granny could unplug them once in a while

there are always loopholes....

as to Bill's original Q, i would further add.....
"does the NEC address extention cord use?"

305 & 400 aside.
