IMHO rcwilson is on a good path and we all agree that 5m can be safely 'ignored' from engineering point of view...but I am looking for a proven way/method to demonstrate this to my educated client.
My feeling is that IEC287 derating formulas are obtained for lim d->inf, where d is the length of...
Question to hbarton and to cable calc experts:
what if installation in pipe ducts constitutes 5% (or 1%) of the route? should we still consider this as the worst case for IEC287 cable derating calculations? is there a related clause in IEC or other standard that binds route length to what is...
this should work...

more on this issue.
quoting a manufacturer's technical specification:
"During a fault within the load or a short circuit, the UPS will limit the amount and the duration of the current supplied (current limited), in order to protect the UPS inverter output(short circuit current).
The amount of...
