Immersion Heater & 13 Amp socket.

Zoomup
We were discussing the rating of 13 Amp sockets recently, both double and single types. The rating seems to be 13 Amp. as indicated on the back of the accessories. Yesterday I had to replace a 13 Amp. single socket that became faulty. It supplied a 3000 Watt water heater. Did the 13  Amp plug burn out? No. Did the socket burn out? No. But the socket switch terminals welded together and would not switch off. So I fitted a 20 Amp double pole switch instead. So, even if a 13 Amp. socket is marked 13 Amp. it may not deliver 13 Amps. reliably, perhaps the makers apply "diversity" when calculating the load current and sizing the contacts for their 13 Amp sockets.

    ... but was the accessory allowed to roast for 10+ years in an airing cupboard with the poorly insulated jacket described above...at full load because the thermostat was shorted and had been for a while, between each one of those cycles.




    I can probably count on my thumbs the number of times that we have used the immersion heater during the 20-odd years that we have lived here, but yes, in some circumstances it could be overloaded. However, (a) wouldn't the boiling water alert you to a problem, and (b) wouldn't the leccy bill be a little concerning after a few months let alone 10 years?
