Just hazarding a guess but...
if the T&E colours are changing to
BROWN=LIVE
BLUE=NEUTRAL
then I guess that Neutral for 3 phase will be blue.
Should make life very intersting/dangerous.
"I have a BLACK wire"
Is it
a An OLD NEUTRAL
b A NEW L2
"I have a BLUE wire"
Is it
a An OLD L3
b A NEW NEUTRAL
At least you will know that if it is Red or Yellow is should be a Live
wire.
There is another interesting thing. Telecomms Signalling Earths used to be
run in either Cream or Grey wire to differentiate them from Protective
Earths which are Green/Yellow and the Grey has now been chosen as L3 !!!
Bloody harmonisation :-(
