Off topic I know, but has anyone ever come across an IEC C13 "jug-plug splitting" cable with two male (C14) ends, the sort of cable you'd want to use if you had two power supplies in a rack but only one power socket available? I'm after a supplier near Auckland. I can source from US but i'm wanting them this week. Cheers, Joel van Velden

This is *not* the way to acheive redundant supplies. Its a way to send yout co-workers back to their family in a box. You should not find a dual male to single female iec lead for sale anywhere. Best look for an auto transfer switch if you want to utilize 2 power feeds to supply one device. Thanks Rob (on the go...) On 3/11/2013 10:22 PM, "Joel van Velden" wrote:

Rob, you’ve misunderstood the purpose of this lead. It allows you to power two devices from one IEC supply socket, not power one device from two supplies. There is a slight safety issue in that it provides two 10 amp sockets from a single 10 amp plug, which could lead to overheating the connectors and/or cable if both devices pull 10 amps, but it’s not nearly as bad as what you’re imagining!

Ah. Yup just confirmed with Joel. He means 2x c13 oulets not 2x c14 male as originally posted. Much safer indeed. Potential for overloading should be generally low. in most circumstances the pdu or whatever you pull the power should be protected at 10a. So pulling 10a per leg of the y-split is likely to just blow the supply fuse before any melting. Not always tho. So pays to think it through. Thanks Rob (on the go...)

These Y cables are available in Oz at lots of places - and are cheap here.

What you are looking for is generally called a Rack PDU on the Google. (That's somewhat facetious, but, the message is totally serious. It's called a "Why?" cable for a reason.)
