EV Ultra Cable ( SWA 3 core with Cat 5). Termination ?

JHFE

Looking at EV Ultra SWA 3 core cable with Cat 5 data and is raising a few questions.

It is aimed at EV charging installations, however…..

At some point that cable has to enter an enclosure and be terminated.  This could be directly into an EV charger, designed to take the cable, but it could also potentially be terminating at the power source end, into an enclosure with power terminations for the 3 cores ( line conductors and CPC ), e.g. a consumer unit.  

It just seems a bit iffy to have a data cable ( by now unsheathed and stripped back )  entering a consumer unit.  A data cable that has a conductive shield.

Is anyone aware of any regs that specifically allow or prevent this situation?  or is the case of  “allow” is that covered by section 134 and regs such as 134.1.1 “Good workmanship….proper materials……manufacturers' instructions.”  e.g. power elements and SWA terminated to CU with a gland, data cable suitably sheathed ( sleeved ) as it makes it's way back out of the CU to an appropriate ethernet connection?

    Thanks chaps for all the sage advice and observations.  

    I particularly like the method of the adaptable box first to separate the data and prevent it from reaching a CU, then taking only power into a switching enclosure environment.

    As for the separation of power and data regs wise, my interpretation here is that while intact the cable is compliant by virtue of manufacturer specification.  Compliance for successful termination is down to the installer, in line with manufacturer guidance and relevant regulation/s.

    I see this situation differently from that of services laid in the ground at different times by different trades.  IMHO, I would say that the regulations are to providing a means of compliance for a “manufactured on the spot, in the field” arrangement of power and data, as opposed to something designed, tested and manufactured in a controlled environment to exacting tolerances with quality control etc.

    Otherwise, why are they bothering to make something that overzealous inspectors could C1 on every occasion?
