It seems that AMD 2 is introducing yet another big change to colour coding - albeit only for DC systems. +ve is changing from brown to red and -ve from grey to white.
Also functional earths are changing from Cream to Pink.
Anyone know
a) why the change?
b) why the "old" (i.e. brown/blue) colours aren't permitted as an alternative?
(the 2nd question is about being able to comply with two different versions of BS 7671 at the same time - e.g. where legislation demands compliance with an older version but customer requirements are for compliance with the latest version - DC systems being increasingly common in domestic installations - e.g. PV systems.)
