its happened again...the socket is about 20 ft via armoured cable to

Well if it baffled your professional electrician, there's your
problem.

What subnormal idiot thought that a damp kiln room could have any
bearing on socket condition/ temperature 20 feet away?


And just because a professional electrician was used it doesn't mean
that the socket wasn't replaced by the cheapest he could source rather
than the best quality available.

A plug/socket getting hot is a sign of inadequate low resistance
connection or it being under-rated.

What socket are you writing about. A standard 13A socket/plug? (Although
I can't see how you would fit a plug to an amoured cable). Is the switch
heavy duty as used for a electric oven?

I assume the 20ft cable is from the house supply to the socket in the
kiln room - and therefore almost certainly irrelevant to the problem.
Why not wire the kiln directly into a fused connection box with an two
pole switch? The socket is failing either because it and/or the plug
are cheap and nasty, or because of pervasive damp and corrosion.
