Electrical extension cords.
(OP)
Where can I find the code concerning the allowable length for extention cords? For example there is a H&V unit on about 10 feet in the air and there is a cord set comming out of a junction box with an electrical connector that is plugged into another cord set that comes from the device.
I did find some stuff in Osha regs but can't find a maximum length.

I don't think there is a specific maximum length.
RE: Electrical extension cords.
While no restriction on length where permitted, but its not permitted in lieu of permanent wiring as dpc suggested. Your installation will not meet the Code, I am afraid.

If you have the handbook read the commentary below 400.7(A).
Computer equipment cords are covered by 645.5. 400.7A lists permitted equipment.

My own primary extension is 125 feet of 10/3/wG, some type of SJ. Heavy, but what the hey?
And I'm mechanical, don't know much about you guys turf, just enough to get along, or get in trouble.(Where's the smileys when you need them?)
Cheers,

For years, here in Chicago, they did not permit power strips. If they thought there was even a chance that computers would be installed, they'd require sufficient duplex outlets to be installed to support all the PC's and monitors. Then, about 5 years ago, they gave up on that and started allowing power strips.
Yeah, eveyone uses them (even me). But where NEC permits them is beyond me.
