Discuss Breaking Main Fuse Seal.. in the UK Electrical Forum area at ElectriciansForums.net

Whazza you really are opening up a can of worms with this one, do you feel comfortable doing this con unit swap my advice would be if you don't, then don't do it. No shame in saying your not ready to undertake a job.
 
I am apprenticed qualified.

An isolator is the best option but thu charge :(

Do tails "need" to be upgraded? They are 5 metres long and go through the roof space into a cupboard in the hallway (property is a flat)

Well if your apprenticed qualified (Is that actually a word) what did your gaffer do?

Or did they never need to isolate the supply????

Changing the consumer unit is not too big of a Job, but as I don't deal with domestic installations I was after a bit of advice.

All I was querying was what people do with removing the main fuse + upgrading the tails as my domestic experience isn't huge.

I know many electricians who just pull it out and many that get Western Power to put in an isolator. Obviously an isolator is the best option.

Nothing wrong with asking for a bit of advice, if no one asked questions then no one would be where they are now
 
I can't see the harm in adding a DIY forum here, it would save a lot of grief, we would all be prepared and there would be less slating IMO, in fact we would be concerned for the H&S of the poster and be more subtle.

What does "subtle" mean??? :thinking:

Although it is an easy process to remove it, incorrect removal can be either fatal due to the high voltage etc, or end up with a broken fuse or carrier and then you will need to pay them to come and fix it whilst trying to explain to them why you removed it in the first place. This is why they wired with a security seal as to attempt to prevent unauthorised removal. If you remove the fuse, you are in breach of your contract with the supply company and have commited a criminal act.

Although its straight forward enuogh, unless it comes out in one go you are likely to run into problems. I will not touch the main fuse as would rather not have the hassle. If you are going to do it, my advise would that, you shouldnt, but if you do, ensure theres NO LOAD, so switch the consumer unit off, then take firm hold of it and pull it out in one smooth but swift movement. Thats my thoughts anyway.

Personally if i ever had to for whatever reason have to remove one, I would take all measures needed to prevent killing myself, so would ensure I was wearing insulated shoes, appropriate rubber gloves, and some form of mask, then hope for the best. I know this is more than likely over kill, but id rather not do it, just incase it breaks it, as you will not be able to fix it without third party help.

Oh and when you do put it back in, try and get the pins to connect at the same time, and push it in firmly in one go, dont mess about with it.

Best of luck!

Awwww ............. don't be so hard on him .. the poor bairn's only been a member here for five minutes !!!
 
Yeah, but the problem would be that many wouldn't consider themselves DIYers

Well then as they would be a proper sparks with the appropriate diverse training and background enabling them to call their selfs so , they will then be able to take the banter of the " site " cabin in the manner as it was meant when another sparks rips them a new one for asking such a twotish question !
And if it is not the case then let them jog on with a sulk on , until they are qualified too .:hand:

scary stuff i can imagine :/

scares me just thinking about the old cast metal cutouts.....

only thing stopping that from going is the submain fuse feeding that main... what size would that be in a normal residential street !?!?

If your lucky you'll only have to blow 300A if your unlucky 800A
 
I so far have a unblemished record ( apart from a edited post for swearing once , from a mod who the following week went on to let a fair bit out himself !) so i have no opinion on that one .:leaving:

I meant no offence with what I said but you sounded a tad unsure , if you aren't then I have read the signs wrong. Good luck with it a crack on.

Hi .... I didn't mean you ran crying & hiding, but one who shall be nameless certainly did a bit earlier on.

I know you meant no offence and didn't mean to reply as if I took it the wrong way.

Just a few assy comments from other members.

All I wanted was a few pointers
 
Gees all this over the same old done to death question,the red THINGY is a protective cap and are available from boddingtons electrical, if you dont want to pull the service fuse then do it the other way,turn of cu so no load on tails get your insulating gloves on and then using insulated cable crops cut the live tail and after stripping back about 20mm of sleeving insert into live on isolator repeat with neutral tail job done,either way if you get it wrong you get hurt or killed but then again if you have to come on a forum and ask how to do it then you shouldn't be doing it anyway .Training and experience are the key things with electricity.

Well I dont know about you but I personally am getting sick to death of diy wonders coming onto a so called electricians forum! When I joined up it was a good forum with proper sparks and decent discussions,now its more like a drop in for B and Q every diyer and his dog turning up,If he is a proper spark then he will have the appropriate equipment and ppe, I have but then again I'm from an age when we did work live,when we had proper training and before these 2 week training courses that turn out so called sparks who haven't a clue! rant over

Well I wouldnt follow any advice if i didnt feel confident carrying out the procedure,but then again i was trained properly and wouldnt dream of asking about pulling a service fuse but by the same token I would not dream of carrying out a heart transplant as I am not a trained doctor and I know my limitations.

I agree with you on many of your points. I do things at work that I would not advise on this forum. Simply because I can not judge the level of competence or ability of the person asking the question.

I'd much rather change a CU 'live', moving the tails with properly insulated tools and PPE to a temporary Henley block if necessary, than try to pull an ancient pre-war ceramic or bakelite fuse and risk it crumbing in my hand, and risking the fuse-police coming and giving me 20 lashes, or whatever happens these days.
