Many Thanks Eddie, it was Mighty Useful,
I have looked at buying the 21A cable that Express are Seilling as the main bus cables, but I cannot find it anywhere in RS or Rapid Electronics or Maplin's catalogues. The output of my DCC system is 14.5v @ 3.5 amps. Please can someone suggest (with product number please :o) an appropriate alternative cable from the Maplin catalogue?
Many Thanks Graham
