Question on UPS AC Power Cord Length

[ziggle]

Hi folks,

I do quite a bit of telecom fiber-to-the-home deployments that use a UPS for a power source. These devices attach to a home's interior wall and have a 6 foot, detachable, flexible power cord. Some customers have been asking for longer AC power cords. I have been looking through the NEC and I have not seen any discussion of power cord length restrictions for UPS applications. Do you folks know of any NEC or UL restrictions on the allowed AC power cord length?

Thanks!

If it's a standard IEC power cable cable, then Belkin do UL certified cables in 15 and 20 foot lengths.

The only thing that I can see is 110.3 (B). Be sure that the manufacturer is cool with you using a longer cord, especially if it wasn't designed to use one.
