The blades of a standard 20A IEC receptacle are horizontal(http://www.parts-express.com/pe/showdetl.cfm?Partnumber=110-429), those of a 15A are vertical(http://www.parts-express.com/pe/showdetl.cfm?Partnumber=110-432). The IEC plugs will not interchange. If you are asking about wall outlets and AC plugs; the basic configuration is also different for 20A and 15A(125V), a true 20A plug will have one horizontal blade(Nema 5-20), and a 20A outlet a dual-use(15 or 20A) slot.(http://www.elect-spec.com/nema_plgsokt.htm)
15 amp vs 20 amp difference?
Been wondering about this for a while, some power conditioners (Shunyata in particular) and other equipment spec. to use a 20 amp power cord. What is the physical difference between the two? Would the plugs for iec and male input be different and not fit into the regular outlets (ie like the Oyaide GXS or PS Audio Ultimate or do they require a different type specifically just for 20 amp usage? I do realize the amp rating (that they'd draw) between the two would be different. Your help would help to further edudate me, Thanks.
