20 ft via armoured cable to the house,the kiln room isnt damp...the kilns
fine,but the plug gets a bit hot(when it worked)the electrician seems to be
baffled...'must be your kiln'...but i know nothing about electrics so cant
argue the toss!can ANYONE help...its driving me mad....

possibilities:
the kiln draws more than 13A, maybe due to some turns of the heating wire being crossed.
plug or socket not of best quality
fuse not completely clean or not best quality

Also as said, plugs & sockets don't do well running at 13A for long times. Try an FCU.

Only if you buy Cheap.

The type of socket wasn't stated.



BS1363-2:1995 requires for double socket outlets that both socket
outlets have loads applied via test plugs, 1 test plug having a load
of 14 amps whilst the other has a load of 6 amps, making a total load
of 20 amps on the cable supplying the double socket outlet. The double
socket outlet is then subjected to this loading for a minimum
continuous period of 4 hours or longer until stability is reached with
a maximum duration of 8 hours (stability being taken as less than 1
degC rise within 1 h). The test is passed if neither the terminals /
terminations, nor the accessible external surface, increase in
temperature by more than 52 degC.
