    afternoon

    first time since amendment 3 came out that I have had to install a TT system

    I need to install site temps on a plot of land ready for new build flats.

    UKPN will be installing a new PME temp supply

    Am I right in thinking I am ok to take my tails through a nylon Wiska tail gland- through a amendment 3 board using a clamp. with a 100ma timed delay main switch.

    then 30ma RCBO any of the circuits out of here that need them. think they are getting site cabins with pre wired boards in them anyway.

    Cheers

    Why not an Amendment 0 to the 18th Edition DB?

    the subs will likely be SWA yes and yes the cabins will propably has boards in them so 30ma protected there.

    but need the 100ma upfront as will be a TT for a construction site

    but my query is more re tail entry into a metal board on TT.
    is just using a plastic gland and a tail clamp satisfactory

    Get one of the Whiska glands for the size of tails you are using.

    It’s not a dwelling so use a plastic board.

    Would you not consider a 100mA time delayed RCD?
    EDIT----Apologies in post one you said T/Delayed it had gone from the next post but assume still being so. Metal or plastic preferably a IP one.

    That looks like a Vector enclosure. Use them quite a bit for IP-rated stuff (with Gamma enclosures for insulating enclosures indoors not requiring IP rating).
