Fuse Seals

[deejay]

Newbie Question:

What’s the general consensus with cutting the main fuse seal for a consumer unit change? I’m aware of the requirement to contact the DNO, but just wondering what the done thing is in practical terms?

The logistics of getting the DNO to cut the fuse can be impractical, especially in the current climate.

If you are getting permission, how are you going about it?

Thanks

What is the old saying?

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.

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.

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

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 ?
