Despite being rated at 13 amps, most sockets and plugs aren't happy to
carry that for very long periods. They are a domestic connector and really
for intermittent use at full capacity. As with a kettle or washing machine
etc. Hence things like 13 amp water heaters normally not plugged in, but
hard wired. Same sort of thing with storage rads.

Even more so if cooling to the socket/plug is restricted in any way.

The answer is to go for an industrial 16 amp plug and socket - if indeed
it has to have a plug/socket arrangement.

There is also a 32 amp, which is perhaps better if it is protected by a
32A MCB, as an earlier poster pointed out. Of course you should be using
30 Amp cable too. (Sorry about the URL)
