Breaking Main Fuse Seal..

[whazza22]

Hi everyone,

I'm sure this topic has been risen plenty of times.

I'm a qualified electrician and I am going to replace a consumer unit for a relative. I am not registered with NICEIC or NAPIT so will be getting it tested by the council.

Can anyone explain the procedure for removing the main fuse as it is sealed?

I know it will never be checked but would just like to know what everyone does. It's absolutely crazy that a qualified electrician is meant to call western power to remove the seal or replace the seal, especially if they have a business to run!!

Thanks in advance.

Not every install as a rcd!

And I'm no Electrical Trainee, I did my years at college. And have 10 years on the tools.

30-50 would be a better number, I missed a 0 off. But my point was its not the voltage it's the current. And you shouldn't be any less worried about the supply in a install than the supply at the main fuse.

I'm not pretending I know everything

That's why I joined here. Plenty to learn from u guys.

thats more like it, the thing is there are quite a few of us on here with over 3 times your level of experience,and due to the way things are going with this forum at the minute we are getting tired of the diy brigade coming on here pretending to be sparkies.just think for a minute before you post and it will help you to avoid getting leapt on by a bunch of irate sparkies,the way its going we tend to judge you by your posts not by what you say is your level of experience.

Well thats me educated then,the only question is if it takes only 3 milliamps to kill then why have 30 milliamp rcd's ?I think you will find it's actually 50 milliamps or above that can kill.I have put the figures up before but this time I cannot be bothered,seems like we have another Electrical Trainee amongst us.

30mA is officially recognised as being the threshold of heart fibrillation.

It depends very much on the actual circumstances a person is in, at the time of receiving a shock, as to what value of current will/can actually kill you. Obviously 10mA offers a better protection than 30mA, but can still have the ability to kill. US GFI breakers and protected outlets are all generally rated at 6mA at 120V/240V but are very prone to nuisance tripping

30mA has been chosen by Europe to all attentive purposes, as a compromise between providing a good degree/level of personal protection from electric shock and the all too familiar occurrence of nuisance tripping.

Exactly but it still isnt 3milliamps,which is what the op stated. lol

Sorry for the wrong number, I know I have a lot to learn still that's why I'm here.

The point was you can die changing a light just as easily as messing with a main fuse in the wrong circumstances.

don't bother, you either know it or you dont,lol. trust me you'll never find it on google.

 

[Robert Turnbull]

I can't lol, I'm intrigued now

You can die falling off a ladder changing the lamp. It's all a matter of priority and using common sense and, of course, a little experience comes into play.

I would add that not only should you think for a minute, but maybe you should check what you've typed before you post it - just to make sure you've not missed-out an "0" here & there.
