E.L.V. Colour Identification.

Zoomup

I have just been helping a neighbour with his new camper van. Long story short, I ran a cigar lighter extension lead from the cab to the under-vehicle leisure battery. The lead originally had a male plug at one end and a female socket at the other. I cut the male plug off for a connection to the leisure battery. The flex is a white figure of 8 with one conductor marked with a black stripe. After installation I decided to double check the polarity of the socket in the cab for polarity. Low and behold the centre pin was negative and the outer ring positive, thus back to front. Why do the Chinese use black as D.C. positive indicator?

P.S. Edit. Add. I have just found this..........

    Hopefully with a suitable fuse - not too close to the battery itself and the pre-fuse wiring reinforced against faults (A721.55.3.6).

    The fig. 8 cable is protected by a 15 Amp blade fuse at the battery position contained in a closed weatherproof fuse holder. Where necessary the fig. 8 cable is oversleeved with P.V.C. sleeving to afford additional mechanical protection. Its run is high up next to the chassis to be out of the way of road debris that might be thrown up,  The cable will only carry a trickle charge from a dashnboard mounted 50 Watt solar panel via its control box. The battery is a leisure battery only, not the main engine starting battery. The prices have gone up frighteningly for these of late.
