This email is regarding the proper and/or allowed use of the IEC 60320 C13/C14 connector (typical Inlet connector used on PCs and IT equipment).
1. If I am understanding the rating correctly, it appears as if this connector is rated 15 amps in North America (NA) (UL/CSA) but only 10 amps in Europe (EU). Is that correct? 2. In NA a standard 115VAC receptacle is rated 15 amps, however, the Electric Code allows a 15 amps receptacle to sit on a 20 amp circuit. Also, a 15 amp plug will plug into a 20 amp receptacle. So I assume that the IEC Connector can handle 20 amps or protection of the IEC connector is assumed to be downstream by the Overcurrent Protection Device (OPD) inside the device. Is that correct? 3. In EU a standard 230VAC receptacle is rated 16 amps yet the IEC connector is rated only 10 amps. So can the IEC connector handle 16 amps (fault current from a 16 amp circuit) or is it assumed the downstream overcurrent protection device inside the device will protect the IEC connector? Hypothetical Case: A device that draws a max 15 amps at 115VAC and 8 amps at 230VAC, can this IEC connector be used when the only OPD inside the EUT is rated 15 amps. (lets assume this is the max stead state current and the average current is only a few amps). I know the IEC 60320 C19/C20 connector is rated 16A/20A but I would have the same questions on a device that draws between 16A and 20A. I hope I explained this well enough.
