3 meter rule.

 

[trev]

3 Metres then a switch fuse should be used. Where the DNO gets it from I have no idea.

 

[Nicholas]

Sorry, what's the 3 meter rule?

 

[Nicholas]

Ok so 3 meters from the fuse to cu?

 

[trev]

If the service head and meter are more than 3 metres away from the CU then a switch fuse should be installed after the meter
Something like that anyway, I'm knackered and have a blinding headache so can't be bothered to go and get the proper info.
Sorry mate.

 

[Nicholas]

Or tails from meter?

 

[Nicholas]

Oh I get you now. I keep typing to slow lol. Ignore my little messages.
thanks for your help guys. His is definitely longer than 3 meters.

thanks guys. Sorry for the bad explanation!

What's the point in that? If the cut out has a 100A fuse why then put two in sequence? Can't see the need. I only bother using a kmf if the mains is ran in 16 te and dumb it to 80A. Plus the dno supply a dual pole isolator.

Dear god!

I’m not surprised you have a headache Trev, I’ve just waded my way through this drivel.

The length actually varies between the different DNOs, on a recent meter move by ukpn the paperwork clearly states a maximum of 4metres.

The point is that the DNO specify a maximum length of tails which are allowed before the consumer must provide their own protective device. Generally this is 3 metres but some allow 4 and others 2.5
