The NEC (NFPA 70) talks about “continuous currents” and when to apply the all-too-familiar 125% rule. Canadian Electric Code (CSA part I) has same requirement. The IEC seems to have avoided it.
Ralph McDiarmid Product Compliance Engineering Solar Business Schneider Electric D 604-422-2622 From: Kunde, Brian [mailto:brian_ku...@lecotc.com] Sent: Monday, October 09, 2017 8:31 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] NEMA 5-20P with IEC 60320 C13 It is my understanding that according to the US National Electric Code, 15 amp receptacle are derated to 12 amps max., and 20 amp receptacles are derated to 16 amps. IEC 60320 C13 connectors are rated 15 amps in North America. Do I derate them as well or can I draw 15 amps continuous from the C13 connector? So here is the big question: If I have a power cord with a NEMA-5-20P at one end, IEC 60320 C13 at the other end, and 14awg cordage (rated 18A), can I use/ship this power cord with a product rated 15 amps? Thanks to all. The Other Brian ________________________________________ LECO Corporation Notice: This communication may contain confidential information intended for the named recipient(s) only.
