Would I be correct in assuming that the supply cable which enters your house has been (in theory) calculated in such away as that there will be no volt drop across it as to ensure that 230v (or thereabouts) is at your DB and available for all your circuits, providing they have ample size conductors for their individual purposes. And would I also be right in saying that if you supplied a submain at the bottom of your garden which had a volt drop of 5volts along it, then every circuit being supplied from that submain wont be allowed the usual 3% allowance for power and 5% for lighting as it has already lost 5 volts through the submains supply cable... I know this is probably a silly thing to ask but I love being double sure...
