galvanised trunking segregation

[Simonslimline]

dado trunking must have the sort of set up with dividers so must be allowable, just seems "wrong" to have data cable in the same trunking as 230v

usually on bigger jobs the data/fire protection is subbied out so never had to worry about it either really lol

Metallic trunking is available with divider also.


Same here, except we install all the containment for the data, fire and bms also.

the data guys installed their own tray on the roof beams at both factories i rewired, our traywork was on the floor and they basically mirrored our routes on the ceiling, there were places the cat5/230v met in the same containment with data sockets next to 230v sockets for servers/computers

as long as every possible effort it made to avoid interference it seems "good practice" but possibly not enforceable by regulations

the existing data cables were wrapped around 3 phase and their routes were as the crow flies across the loft floor

was glad to get to the end of that job, shame the factory insisted on keeping all the scrap

It’s very common for data and 230V to be used in dado trunking.
Not so common for data and 230V to be used in the same metal trunking, ‘T’ pieces are quite convoluted.
Have seen data and 230V on both basket and tray, both with and without dividers.
Never quite understood why 230V alarm cables are kept away from 230V power and lighting cables.
Not aware of any requirement in BS7671 for them to be segregated.

Cables can be in the same containment as long as they are insulated to the highest voltage present.

Compartment trunking saves installing two lots of containment, we used it in a warehouse which had lots of offices, data cables were in the top compartment, and where they dropped to computers and lengths of dado trunking, 20mm conduit was used to bridge the 230v section.

Never worried about data bridging 230V.

Where they cross it should be a 90degrees preferably

It may have been an old wives tale, but I seem to recall that as long as they cross at 90 degrees and do not run along side each other for more than a metre they should be fine.
