Dear all,
I wish to replace my old re-wireable fuse consumer unit. I have arranged for the electricity co. to come out and fit an isolator in a couple of weeks time.
I don't think the existing arrangement is 16th edition compliant. The company fuse and meter are in an outside cabinet mounted in the wall i.e. the meter etc are mounted on a board attached to the internal concrete block wall. The consumer unit is mounted indoors on other side of this wall, roughly a meter higher-up. Currently the meter-tails run up inside the cavity wall and the circuit wiring from the consumer unit goes up inside the cavity to the 1st floor.
As I understand it running cable in the cavity of an external cavity wall is no longer permitted (or just not recommended?). None of the tails/cables are inside any conduit.
Can I leave the existing arrangement as I'm not doing a complete re-wire?
I could probably run the meter tails inside some (fairly flexible) plastic pipe if that makes any difference. As I understand it the meter tails should be run straight through the wall (in a conduit) but I don't want meter tails running up the internal wall where they will be knocked and bashed by all and sundry or a consumer unit at shin level.
With regards to the existing circuit wiring I'm tempted to put a small cabinet (presumably there are specs. for fire protection?) on the (wall above on the) first floor for use as a large junction box, run new cables up the wall from the consumer unit to the cabinet and connect there to the existing wiring. (my reasoning being there's bound to be a cable that just too short and will simplify replacing any of the existing wiring if required)
Does anyone have any comments/suggestion?
I have access to copies of the wiring regs (and some other texts e.g. onsite guide) if it would be easier to point me towards the relevant sections.
Many Thanks
Jim Ingram
