Meter Tails in Ducting

fiftyhertz
Hi All,


Working on a street lighting project, which requires a DNO supply. Now, up to this point it has been fed from a SWA as a temporary supply. We are in the process of changing it to its rightful metered supply, however the original installer did not allow space for the cut out/meter. My thinking is to install an adjacent pillar, to house the fused cut out, meter, and duct between the two. 


My question is can meter tails be ducted, they are double insulated so i cannot see why not. Alternatively,, fit a 80A fused switch after the meter and gland from that and run in from the connecting ducts to terminate into the DB. Has anyone used SWA after the meter?


Many thanks

    If they're going underground then the cable needs to have an earthed metallic armour or sheath to suitable for use as a c.p.c. etc - unless you can show that the ducting provides sufficient mechanical protection to provide equivalent safety (which is usually difficult).

    Noted, SWA it is.

     

    Some Numpty has not left enough room in said feeder pillar for the cut out/meter making in unadoptable



    I'm slightly surprised that street lighting need metering - isn't it usually paid for by licence priced on its nominal power consumption? But anyway, any mileage in simply replacing the pillar with a larger one?

    The Lighting department at the council have requested a metered supply, from my understanding the nominal consumtion is correct if the supply is 500w> and an umetered connection can be applied for. It does make sense to put in a new larger pillar, but it is proving a nightmare trying to coordinate the DNO and the electrical sub-contractor.
