Hot Fuses....
Hi,
Some guidance please everyone, apologies for the numptie descriptions and assumptions, i hope they make sense to you! The electrical setup in my house seems pretty straightforward. The thick black supply cable that appears from out of the ground feeds into a black unit stamped Norweb and sealed with a wire and lead seal (presumably this is the main fuse). From there two tails feed into the meter then into a switch (isolator ?) and finally into a 100A split load consumer unit. The main fuse (stamped Norweb) is always hot to the touch (on the left hand side if it matters?) even when the meter is turning slowly. When say then shower (9.5Kw) is running the fuse is hot to the point where its not possible to keep a finger on it for more that 2 or 3 seconds without it being painful and there is a definite smell of, not burning, but that similar to switching on an electric heater thats not been used for months. I guess the question and concern is whether this is normal? If yes, great, if not, what do I do next please? Electrician or Electricty Board? Hope you can help, Regards Ron |

That is the supply co.'s fuse and is their responsibility - it should not ever
get hot and only under rare occasions get warm (full load for a while) i.e. cooker shower and electric heating on. If it does, especially under light loads I would say get them in as a matter of some urgency as something is definitely not right ! Nick "A_H" wrote in message ...

Sounds like there is a poor connection to at least one side of the board's fuse, so it's them you need to call, and sooner rather than later would be good. :-) Rick |

Thanks a lot for the advice. For info as soon as I got the responses here
(three quick replies - all saying *problem*) I called up United Utilities who advised that any excessive heat or a burning smell constituted an emergency and an engineer has been and gone (seems a decent response - around an hour from call to visit on a B Holiday?). Anyway, he took a look and has advised that the unit (I'm assuming the fuse unit thingy) needs replacing with a new one. Now awaiting another call from an engineer to do this work (later tonight or tomorrow morning ) and in the meantime I've to keep the loading as minimal as possible (no showers/immersion etc) until it is sorted. Having said that the engineer must've done something because the heat has gone and the bit that was hot definitely is'nt hot anymore. Having spent a few days *not* going with my gut feeling that things were not right and feeling a bit of a plonker for not making the call sooner I'm finally glad I asked you guys and got the right advice because something clearly is/was wrong as you suggested from the off. Thanks a million! Regards Ron "Richard Sterry" wrote in message ... "A_H" wrote in message ...

It was somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Dave Stanton saying something like: On Tue, 28 Dec 2004 01:20:11 +0000, Bill wrote: Well Ron it has been 9 hours now since your posting.

Thanks a lot for the advice. For info as soon as I got the initial responses
last night here (three quick replies - all saying *problem*) I called up United Utilities who advised that any excessive heat or a burning smell constituted an emergency and an engineer called (seems a very good response - around an hour from call to visit on a B Holiday?). Anyway, the engineer took a look and advised that the unit (I'm assuming the fuse unit thingy) needed replacing with a new one. In the meantime I was to keep the loading as minimal as possible (no showers/immersion etc) until it is sorted. Another hour on and a pair of engineers called and spent a couple of hours doing some more work. As of about 11pm last night I've got a shiny new fuse 'thingy' (100A fuse). Looks like they've also moved the meter and replacd the various tails that feed everything. a few hours from start to finish and I have to say I've been impressed with the whole thing. Having spent a few days *not* going with my gut feeling that things were not right and feeling a bit of a plonker for not making the call sooner I'm finally glad I asked you guys and got the right advice because something clearly is/was wrong as you suggested from the off. Thanks a million for the help and concern, sorry I didnt get back earlier but as guessed the power was off until late and then family visit type stuff has kept me away since. Cheers again everyone, Regards Ron |

strung together this: Probably an oxidised contact was causing the heat - he'll have cleaned it up, but wants to fit a new one anyway. I've had that before, dodgy main 3 phase cutout with one phase down which I cleaned up a bit and it sort of worked, but wouldn't have lasted. 9pm on a Saturday it was, so I managed to get an engineer out to site within an hour and had a complete new cutout the next morning, (which was Sunday late morning, when the MEB disconnected the overhead line from the transformer feeding the houses in the area, I sent the customer round to tell everyone to pause the cokking of the roasts!) -- SJW Please reply to group or use 'usenet' in email subject |
