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?

Does the use of this cable type comply with BS 6701 for Ethernet (or indeed EIA 485) ? This standard is referenced for telecommunication cabling (which includes information technology and “data” cabling and controls comms) in BS 7671 (Regulation 110.1.3), and therefore to comply with BS 7671 you should also comply with BS 6701.

Clause 5.4.4.2 “Protection of telecommunications cabling and attached equipment” (which is not for EMC, that is 5.4.4.1, but “local regulations for safety” as stated in Clause 5.4.4.2) requires at least 50 mm separation between power and telecomms cabling, even with a partition or where the LV cabling is an earthed conduit or trunking, or in 'insulated and sheathed' flex!

However, that is only for indoor use … if the cable goes outdoors, it may require installing in accordance with BS EN 50174-3 and greater separation distances may be required.
