I am not going to get in to another one of your thread hijacking drawn out pedantic arguments,

So why did you hijack the thread by writing that untrue rubbish motivated by your pathetic and childish desires? Your criticism had nothing to do with what I wrote - it was a pure ad-hominem fallacy. You advised the OP to take no notice of what was written simply because you made some incorrect guesses about why it was written and didn't like what you had imagined into existence.

Your behaviour was shameful.

so I will simply say that, rationally, you didn't post that in order to assist the OP,

Untrue - they are all valid questions, with a genuine safety basis. And you might like to consider the fact that they weren't all originally written by me - a number of people were involved in drawing up the list.

you posted it to make yourself feel smugly superior.

Untrue. That is nothing more than a personal opinion of yours. It has no basis in fact, you can produce no evidence to indicate that it might be true.

You mounted a personal attack on me for no reason apart from a personal dislike of me.

Would you please explain why you think that is in anybody's interests?

Well, this forum is here to help people with electrics, not to boost your ego with embarrassing displays one-upmanship and the belittling of strangers.

And helping was, and remains the intent of that post.

I will repeat my request - would you please put forward a rational case explaining why the questions I asked are unimportant, and can safely be ignored by anyone changing a CU.

Just inserting the word "rational" into a criticism of what you think my motives were does not count as a rational analysis of what I wrote.

Stop moaning about why you think I wrote it, and focus on what I wrote.

Please explain why what I wrote can safely be ignored by anyone changing a CU.

Here we go with some pics of the meter & fuse, and a couple with the fuse removed.

Fuse looks ok close up, no signs of arcing etc.

Thanks again for all the help & assistance with this - its really appreciated.

You naughty boy! What would the DNO say!

No idea why the RCD has stopped tripping though. It's highly unlikely to be anything to do with the main fuse - I can't see how it could be.

I wonder if one of those bizarre type of upstream faults that sometimes occur might be causing a problem? Not sure what type of fault that would have to be though.

Because he's pulled the service fuse out.

Sorry....

Could I unashamedly bump this up in case someone has an explanation?

2 days on, and the RCD still hasn't tripped again - confused? I certainly am...

 

[LoveRocket]

I have no explanation, but I also don't have much faith in your RCD.

Get someone with an RCD tester to check it out - it could save your life one day.

has it tripped again since replacing the main fuse?

it could have been damp in the fuseholder making a bad connection

with the fuse out, tighten the screws at the top and the neutral to make sure.. ( don't touch the ones under the red cover.. but you knew that right? ).

No its not tripped at all since I had the main fuse out - weird.

I'll certainly tighten the screws (not the red ones.....lol)

could have been a bit of damp / oxidation on the fuse blades creating a high resistance joint and causing voltage fluctuations with heavy load use.. ( ever notice your lights dimming when the fridge or something comes on? )

might have been something to do with weather ( it's been fairly warm and dry the last week.. see if it comes back when it gets wetter out.. ) .

could be that you knocked one of the supply cables a bit when pulling the fuse making a better connection and aleviating the voltage fluctuations..
don a pair of marigolds and give them a wiggle.. any crackling or fizzing noises call your supplier and tell them..

Thanks,

Tightened up the wires, a couple were quite loose so I'll wait and see over the weekend if it trips again - been a few days now since it last tripped, which it was doing few times a day until i pulled the fuse.

Like you say, could be the oxidisation on the fuse blades, or weather.

Anyway its ok for now, so I'll just monitor it and see what happens.

Thanks

Or the other possibility it that your RCD was on it's last legs (hence the strange tripping) and that removing and reapplying the power has finished it off, so it's now completely useless.

Get. It. Checked.

It's a five minute job for someone with a tester, and you might even find a spark who'll do it for a slab of beer.

 

[ban-all-sheds]

Before you do anything, get someone round with an IR tester and RCD tester, and see what's what. Does your mate have this equipment?

PS. Ignore Banal-sheds, he often posts like that as it helps with his inferiority complex.

LR - just thought I'd alert you to this, in case you hadn't seen it:

Some issues:
Don't forget that you will have to divert/move/extend all of the circuits that connect to your existing 'fusebox'

When you change to a new consumer unit you will need to properly test all of the existing circuits first. Do you have the necessary and calibrated test equipment?

You will need to check that your earthing conductor and equipotential bonding is up to the sizes specified in the current regulations. Are they.

Changing the fuseboard is notifiable work. Check out what you need to do in the WIKI

as I'm sure you will want to go and tell the OP on that thread to ignore TTC.

Unless, of course, your criticism of what I wrote here was motivated not by a disagreement over what the words were, but just over who wrote them? But no - surely nobody could be that pathetic and stupid.

Hi fireblade not sure your right about notification up here as long as a cert is issued with all relevant info. planning office here dont want to know unless it,s a alteration to the actuall building but were a bit vauge. but you do have to get the guy from scot power to pull the fuse, wink wink.
