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?

    Indeed - and ‘makers instructions’ if there are any, take precedence. Clearly inside the cable the cable makers rules about clearances apply.

    If there are instructions, I imagine they would say something along the lines of “keep power and data apart once you have removed the outer sheaths”

    I might slip a bit of sleeving or maybe even thin flexi-conduit over the innner cores once split out, until very clearly away from each other, if there was any doubt at all.

    I too like the break-out box idea. A single point where the absolute minimum of mains voltages get close to the unsheathed data cables - much as you have with the computer /hub, IT rack  etc it connects to
