The 6MM core running from may shower to fuse box is getting hot and
smelling pretty bad when I shower.
The cable has been installed since I moved in over 10 years ago.
I replaced the shower which was 8.5 KW so I assume that the 6MM was
fine and didn't need replacing.
I assume the cable has been installed over 15 years ago.
Could this be the age of the cable or simply the shower when turned up
I have a 30amp fuse in the distribution box.
any help appreciated.
Get the connections checked at the pull/wall switch and at the shower and at
the fuse box. The bad smell (like fish?) is probably a result of a loose
contact that results in burning the cable. A 30 amp supply for a 6mm cable
is usually adaquate. Installation methods and voltage drop need to be
accounted for though. It is worth remembering that cables do get warm when
fully loaded but I am concerned about hot.
Many thanks Adam.
I have traced the cable and the Combi boiler is feeding of this cable
via a box on the wall.
so basically 6mm cable is cut feeds into a box and the combi boiler is
using this feed.

I think the Wiring into the box may be lose or the box basically old
Looks a bit of a botched job but it was here before I moved in.
Can't get to it easily and without light.
will replace the box and see if that helps.
Sorry for the delay. Blueyonder have not done newsgroups this weekend.
Well spotted about the 35 amp load, I misssed that. A 30 amp fuse will not
blow at 35 amps for a long time (if at all), but the fuseholder will not
overheat. It is still not good practice. Depending upon the installation
method a 40 amp fuse may be used.
It could be the cable breaking down or the connector.
Is 6mm OK for a 8.5 Kw??
I had a fishy smell in my bedroom???? couldn't trace it to anything, had the
carpet up & everything, then suddenly I had the main light on and the smell
was there and immediatley realised that was the problem, the fiitting had
broken down, only a few years old aswell.
Hope this helps
If the cable run is long you may be getting in to trouble - modern good
practice recommends 10mm cable and 16mm if the cable run is over 20 metres.
If you have an older fuse box with a cartridge fuse recommendation is 8kw
