    Dado trunking

    I’ve got some Centaur dado trunking from years ago (2 1/2 lengths of it) from CEF. Got some lid for it, but not enough. Does other makes of trunking lids and boxes fit? I’m looking on eBay for cheap accessories rather than go back to CEF just for my own office.

    UK Twin and Earth in metal trunking

    Hi guys, I had to carry out some alterations to a domestic installation the other day and was pleasantly surprised when having to run a new circuit how neat the CU was. It had 75mm metal trunking installed to the CU with bass bushes installed. A lot of effort had gone in to it to keep it neat...

    Plastic trunking over a door way

    The use of fire-resistant clips to avoid premature collapse of cables is obviously a good thing, but what about when the cables are in plastic (PVC-U) trunking that offers metal clips for this reason. The reason for asking is I am looking at some options just now (Marshall-Tufflex Mono Plus 20)...

    Dado metal trunking

    Looking to put in some dado style trunking for a few power circuits and some Ethernet sockets, ideally metal type from a fire/EMC point of view. I had though of using the Marshall-Tufflex "System 130" (or maybe the bigger 170) steel system but wondered if the folks on here have any better...

    When did seperate earth's in trunking become fashionable?

    Next question on the date my install game. When did the practice of installing seperate cpcs in trunking become the norm? The 'original' part (the rewire when the VIR was replaced) of the install I am trying to establish an age for is entirely in enameled trunking which has been used as the...

    Securing cables & trunking to prevent premature collapse.

    Just wondering how your guys observe the reg, for preventing premature collapse of cables in plastic trunking, when securing to plasterboard, i.e. dry lined or plasterboard stud walls? We’re having some additional fire alarm work carried out, and they mention some ‘clips’ to comply. I was...

    Unused conductors in trunking

    The client has decided that redundant circuits, created by us by decommissioning obsolete equipment, should be, in the first instance, removed completely. If this can be shown to be unsafe, cutting back a metre at each end would suffice. I seem to remember a regulation that unused conductors in...

    Classification of Busbar Trunking

    Hi all! I was having a bit of a to do with a colleague of mine regarding busbar trunking. We both agreed during our inspection that a busbar deserves it’s own test sheet as it is a method of distribution which each “tap off” denoting a separate circuit. However I argued that the ‘Zdb and...
