Is it normal for plug on end of flex type RCD to have a warm spot?


AIUI it depends on design of the RCD. I have plug-in RCD adaptors that
do that.Â*Â* They include one where Contactum even warn that they do.

Its normal for a plug on *any* flex to get warm at full chat.

13A through a 13A fuse is bound to make it nearly hot enough to melt, if
its gonna work as a fuse at all...

Its also normal for the flex to get hot, as those of us who have run
multiple power tools and a kettle through a coupled up reel of extension
cable know to our cost..

Yes, if it had been in use in such a situation I would have put it down to
that though in the situation it is used for it never carries more than 5
amps.
This warm spot was with it tripped though so no load,and well away from
the pins which were cold.
Reckon it must come from one of the windings passing a small current even
while tripped.

Funnily enough one of your fellow flyboys asked a similar question about a
very similar unit.
