A couple of questions

[the_mouse]

Question 1: is it acceptable to modify the meter mouting board or does it belong to DNO? i need to trim off 35mm to allow a new consumer unit to fit, an alernative postion isnt really feasable, because it would suffer impact damage.

Question 2: When running main equipotential bonding on outside of building is it ok to go through the wall sharing the hole with other services e.g. supply cable, gas pipe or waste water outlet?

Question 2: When running main equipotential bonding on outside of building is it ok to go through the wall sharing the hole with other services e.g. supply cable, gas pipe [NO] or waste water outlet? I'd say no to all three. I use 10mm plastic heating pipe to line my hole for small cables.

Ref Q 1

If the new board will fit in if you trim off 35mm, i take it that the levels ie. the dno board has ceramic spacers behind it and its that much further off the wall. is it possible to bring a new back board on with to fit your CU out to the same level or slightly further? Hope I explained it the way i meant it....

Ref Q 2

Personally dont see aproblem with the waste pipe option

I agree pull the cu away from the wall and over lap the meter board, i space my boards away from the wall with cut conduit, the cables are the much easier to run

gas pipe - No, [sure its says something in onsite guide] waste - cant see why not and supply cable - probably not.

I`d be happy to bring the main gas bonding conductor through the wall with the gas pipe, if there was space.........

why would you be doing that if you were bonding within 600mm of where it entered at.?

oh, I get it now, yes ,

it all seems better now I have actually thought about it,

you are bringing the MEB IN.

I dont see any problem with that at all.

I would do it.

+2 I would too. What could possibly be a problem with a cable touching a pipe (insulated) that it's bonded too anyway. Cheers
