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?

    I am not saying the product is unsafe, but the practice (of using the product in a fixed installation as part of the data link) is arguably deemed to be unsafe by BS 6701.

    To that standard, physical separation by minimum distance is required even if the data and power are in separate containment. It's not clear now a cable containing both power and data meets this requirement. 

    BS 6701 also has increased minimum fire performance requirements for fixed installation cables that exceed the minimum in BS 7671.

    (I'm not saying this cable doesn't meet those, I haven't checked … just that BS 7671 is not the only standard to consider here.)
