Fuse Seals

[brianmoooore]

There are several around my area (including my own, before the meter was replaced), where whoever fitted the seal left so much slack in the wire that the fuse carrier can be pulled out and left hanging with the seal intact.

Well you all get my seal of approval.

No too small for that task, they are very expensive engraved sealing pliers.

 

[Mike Johnson]

Are you sure they are not used by Rabies? ?.
Or pig farmers? ?

So do they impress a number onto a flag seal ? symbol ? why do you need special sealing pliers ?

But being serious for a minute, if (hypothetically) you were going to pull the DNO fuse you really need to take care if it is anything but a new-ish cut-out in good condition. Even then, you have to make sure it is not on load (so CU(s) already off at main switches) and to wear some PPE like a suitably rated face shield and at the very least something like rigger's gloves to provide some protection against arc-flash injuries to your hand.

If the cut-out looks very old or damaged in any way DO NOT TOUCH IT. In that case your only sane option is to get the DNO folk in to sort it out, as your day is going to end very badly if it shorts out on the incoming side of the cut-out fuse.

Was recently asked to comment on an EICR that was done for the church my wife goes to (covid permitting) because of a couple of C2's (no RCD's and a couple of unswitched sockets that "didn't comply with the regs") yet no mention of the poor condition of the service head (fused live and neutral) and the multiple 951 and P clip earths on the incoming cable, a quick call to the DNO and 6 hours later new service head and earthing all sorted.
Was interesting seeing the DNO guy getting his blow torch out to warm the door of the old service head that had been sealed shut because the pitch had bubbled up from the cable chamber and then hitting it with a big hammer, once opened he found the neutral fuse had been glued in by the melted pitch
Having a chat to the 2 guys on site and they couldn't understand why so many electricians don't like calling the DNO to have service head and earthing issues sorted, when I suggested it might be because the meter / service head seals were missing I was told they weren't interested unless there signs of theft of electricity.

that's extortionate.

these better price.

Even cheaper if you have a chat with the DNO man when he's swapping a service head or fixing the DNO earth for you

oh ok... explains why they're expensive then... but why do you want your initials and number on the seal ? What make are those pliers ?

Presumably so he knows if anyone has tampered with it in the time before his next visit.

Hi, I'm a long time lurker to the forum and have never posted before so forgive me for not introducing myself formally before.

This post interests me, as I would like to know why it is thought that we can't cut the seals. If I need to cut the main tails then I can't do it live so I have to cut the seals to pull the fuse.
I have never been told by any official representative of a DNO or even by a sign on or near to the head that I cannot do this. Without the presence of an isolator, what am I supposed to do and how would I know i am supposed to do something different?

Lots of threads on here about this subject.

Even more in the Arms..... This thread is public ?


Where ever you have worked, there must have been stickers saying not to tamper with this equipment?
It belongs the DNO/Supplier so we shouldn't be touching it. (same with BT master sockets)

Yes, its easy to cut the seal, but you are risking injury by pulling the fuse without training or PPE. Even more so by pushing the fuse back in.

If contacted, the DNO/Supplier will install an isolator, although its troublesome getting them out in this pandemic.

Yeah good point.

Obviously the seals should not be cut and an isolator should be requested.

That's that sorted

 

[brianmoooore]

There's always a brittle (tamper proof) plastic warning label stuck over the cut out around here.

The pliers are made by Maun Industries who make awesome tools. They are official registered sealing pliers.
