I've got an amp in for repair at the moment which has a high-temperature mains inlet connector and therefore needs a mains lead with the corresponding high-temperature trailing socket, designated IEC C15. At first glance this looks like the run-of-the-mill C13 connector but a closer look shows that the chassis plug has a ridge in it which stops the C13 socket from being inserted. The C15 one has a corresponding groove so it does fit.
I wanted to give the customer a price for the right lead but I can't seem to find any BS1363-plug-to-IEC-C15 socket leads for sale from the major suppliers (Farnell/CPC, RS, Rapid, Mouser, Maplin ...). I can buy them on eBay very cheaply, but you're never sure what you're getting from there and I have seen some distinctly dodgy looking stuff. With something like a mains lead I'd either like a branded product or at least one from a vendor whose quality control ought to be trustworthy. I can buy loose connectors so I could make one up myself (but I'd have to CE mark it). I can also buy converters from C13 to C15 (but why would I want to put an extra unnecessary joint in a mains lead ?). So does anyone know, off-hand, why every supplier is knee deep in hundreds of C13 leads but not one of them offers a single C15 lead at all, except for one of the coiled-spring types that used to allow you to pull your kettle around the worktop, which I did see somewhere ? Or have I missed something ?
In the particular case of this amp it doesn't matter, as it happens. Someone in the ownership chain has obviously faced the same problem as me and has come up with a creative solution. Just take a C13 lead and with a Stanley knife and a hot soldering iron you can hack/melt enough of a slot for the socket to go at least part way onto the plug
(this really is the lead that came with it !):
