Hello Group,

Recently my purchasing department asked me to recommend standards for power
cords.   These are detachable power cords for ITE equipment, both 3-wire and
2-wire.   
Typically the cords are marked with one or more of  CSA, UL, (Dentori T).
The ones we get are typically rated from 6 to 10 times the required current
for a given product. 

My question is, are there required or recommended power cord design margins
for current, voltage, power, temperature range, insulation, etc. spelled out
in IEC/EN 60950 or UL1950 or  MIL-HDBK 217 or elsewhere? 

Thanks in advance

George Stults
