Because 6 AWG with 90 deg C insulation allows supply up to 75A which is probably what those public EVSE are designed to support even though they are connected to 50A breaker and are configured to supply not more than 30 or 40A (the duty cycle setting of the pilot signal).
Having a 10 AWG cord allows 40A if the insulation is 90 deg C, otherwise it is 30A max, see for example the table at http://en.wikipedia.org/wiki/American_wire_gauge Regards, Cor van de Water Chief Scientist Proxim Wireless Corporation http://www.proxim.com Email: [email protected] Private: http://www.cvandewater.info Skype: cor_van_de_water Tel: +1 408 383 7626 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Cruisin Sent: Saturday, January 05, 2013 5:41 PM To: [email protected] Subject: Re: [EVDL] J1772 for DS 50 EV 1 Station If what you say is true, and its not, why do Public J1772 Level 2 charging station use #6 AWG or larger? -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/J1772-for-D S-50-EV-1-Station-tp4660370p4660376.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
