Protecting DNO equipment

[Michaelwgroves]

A House of Multiple Occupation (HMO) officer inspecting a HMO for temporary accommodation has advised tenants might be tempted to play with DNO equipment as it's not in a locked cupboard.

I'd be interested in your thoughts, my view is nothing to do with me, DNO install this and deem it to be safe, therefore I should not touch anything.
HMO officer suggesting locked cupboard, but surly you can't put a lock on DNO equipment, they need access?

At the very lest I'd bang a few clips in for those tails.

Think I might have been a bit more concerned with the electrician playing with the DNO equipment using a BS951 for the home made earth. So should the HMO inspector if he wants to play at being an electrician. Yes I agree DNO not my problem. Would not get involved.

You can lock away DNO equipment.
Yes they would require reasonable access.
Either build a locked cupboard around the equipment or make the room containing the equipment secure.

Depends on the nature of the tenants, the officer may be aware of this hence his recommendation. I have worked in plenty of these places and seen all walks of life in them. Most are happy to roll with life but a few just want to kick to pieces anything they have put in front of them.

I called DNO to replace head, they fitted earth clamp!

That is an old clamp.

I take it the tails are entering some kind of wooden construction at the bottoms of the picture?

 

[Michaelwgroves]

Can I buy a metal box with no back I can simply put over install. I assume if I use meter seal DNO have full access and can reseal when they finish?

 

[Michaelwgroves]

I recall it was there originally, he refitted it. I asked if it was okay and he said "yes"

PVC trunking

PVC trunking

Long as it’s not metal.

As the meter has only been installed for 4 months someone should contact the energy supplier to put some clips on the cutout - meter tails.

If it's going to be boxed in it needs to have a triangle meter lock on it or the meter reader won't be able to get it (unless they've scrapped the compulsory 2 year reading/check as was being proposed recently).
If it's secured with a triange meter lock then any fool could buy one, open the box, by pass the meter and close the box and no-one would know.
If it's left uncovered everyone can see it.

eddy currents on the tails entry as well.

Call them back then it is not an accepted means of providing an earth and they will say it is not their earth if there are any problems in future. They should use the cupro phosphorous wrap around clip I think it is called.

Spring or constant tension clamp.

Is this the one you were rewiring?

I think where those tails enter is wooden not metal so no eddy currents

 

[Deleted account]

He already said PVC trunking

 

[Leesparkykent]

A Hepworth clamp is what you want.

The tails look like 16mm yet they've fitted a 100a fuse ?
