Data cables in electrical control panels

Hi, 

Almost all industrial control panels and others like lighting / automaton, have devices inside of them which have Ethernet ports, connected generally to network switches within the panels. 

BS7671 is quite strict when it comes to routing data and power cabling; in control panels, data cabling (so Ethernet over Cat5 or Cat6 or indeed RS232 etc) is generally in the same trunking as AC (single and three phase). The cables land into the panel separated from AC, but are then right on top of AC inside of the panel itself.

Obviously panel design standards are different. Does anyone know the exclusions / best practice for this?

There are also other subjects like Hybrid cables, for EV chargers, that I think come into question. 

Are there any special distances/creepages that need to be maintained in control panels between power and data? 

Thanks.

  • Reading about EV Ultra cable it actually says on the CEF website the Cat 6A is for the connection of a CT, it doesn't actually mention using it for an internet connection.

    • EV ProInstall Cat6A LSZH Cable is for EV charging unit power and flow monitoring
    • The cable is a combination of power cores and screened Cat6A data cable offering a solution for quick installation including connection to CTs, eliminating the need to run two separate cables

  • Hi, 

    Thanks for your answer. 

    These cables are designed for DMX and audio.

    There are also lots of light fixtures on the market with hybrid power and data cables (DMX over twisted pair). 

    I am sure that this is then covered by a product standard. BS7671 outlines installations, and instructs to follow manufactures guidelines. If a hybrid cable can carry data in line with specification in this format, the installation is then complaint. 

    That’s my view at least.
