S.W.A. Cables in Parallel.

The only problem with cables in parallel is what happens if the current share is unequal - actually a reasonable length helps here, on a short length the details of termination can be significant. So long as both armours, or more accurately any one would operate  the ADS if either cable was spiked, then it is fine. I'd be inclined to perhaps tie the ends together in some way, so they form a pair at the terminals, but that is only so it does not confuse any future person looking at it.

Actually with 6mm and 60A you can have it quite a long way out of balance before it matters - it is a similar problem to the current share on the ring final, and we do not normally fuse the individual limbs there.

The two cables are of exactly equal length and supply a consumer unit. 4D4A does not rate 6.0mm2 anywhere near to 60 Amps.

I'll just stick with 514.3.2 and Table 51 ebee. It is easy to identify cable cores as:


a, They are oversleeved by the correct colour sleeving, or tagged by numbers or indicated by coloured tape.


b, They are identified by their connections at terminations by observation.
