I don't know how many other people here ever get involved with caravan/trailer wiring, but I'm sure we must have some.
Is it just me, or do the conductors in the standard black 12N trailer cable seem to be getting very thin these days? The common return (white) is reaching the point at which voltage drop is really noticeable.
I've taken to running the heavier 12S-type cable in place of 12N whenever possible to get some larger gauge wire and less voltage drop.
Note: For those not familiar with the U.K. system, we generally use two 7-pin connectors: 12N (black) for the road lights and 12S (white or gray) for the supplementary functions - trailer battery charge, fridge, etc.
