I remember a
couple of months ago there was discussion on
 the proper cable for a BA440 power supply (normal North
 American three prong power cord but with a notch where it
 plugs in to the power supply).  Was there a consensus on
 the designation (and any place in the US that sell them)? 
   Here is a copy of a message I sent on 7/22/2001 about this:
   They're are three power connectors in the "standard" family as defined
 by IEC...a low-, medium-, and high-current version.  The low-current
 version is the one we're all used to, 10A.  The one on some MicroVAX
 chassis is the 15A version.  The third is a larger one (20A, I think
 but I'm not sure) that has three flat pins in a triangular arrangement
 but in two parallel planes, with a plain rectangular body.  Tey're
 found on some larger Cisco routers (7513 for one) and on SGI
 Challenge-L systems for example. 
 
Dave, do you happen to have the IEC spec number?
