Good practice wiring in trunk/conduit

[tomasi]

Should all the conductors of a circuit be taped together at intervals along
the length of the trunking they are installed in? to minimize magnetic problems and induced
voltages/currents,the tapes only removed when leaving trunking to go into conduits.
I suppose it makes it easier to identify the circuits and as i do usually do this, i find it
fills the trunking in a neater way without crossovers and bunching.
But is this a regulation or just good working practice?




Can you still comply with part M of the building Regs if you fit dado at skirting level
therefore installing sockets below the 400mm asked for in part M, or is this just a
guide line and you can disregard it,after all what would happen to skirting trunking?

You cant tape the cables together if you get a faulty cable you cant pull it out to replace it.

hi

we do it all the time, looks neater and as you say easy to identify individual circuits. not sure about the regs though.

You aren't supposed to pull cable through trunking anyways.

i dont tape them as its a pain trying to replace one. Never do it in conduit either.

Yeah, thats why it has removable lids.

Definately don,t tape in conduit but trunking yes .If you get a electrical spec.from a consultant you will probably find that it asks for cables in trunking to be grouped into circuits and also the circuits be identified where they enter and leave the trunking and also at 2mtr intervals throught the trunking run

Skirting trunking has been taken off the shelves, generally as you need to stay within the 450 to 1200 mm heights for disabled access. If you already have skirting trunking there you MAY get away with it but it's a gamble in my opinion!
