[QUOTE="Evans Electric, post: 436726, member: 1408"] Ah! Good point Andy . I'm afraid that reference comes from the memory of an old phart who started off thinking in terms of 440V which then mysteriously changed to 415V and then to satisfy the EU became 400V . ( In fact I'm sure I remember many labels reading 500V & 250V ) Same with the reference to TPN as L1 L2 L3 I pretend to know all that but in my head they remain Red - Yellow - Blue . And don't get me started on the old metal isolators & switchfuses that show the opposite colours , so old ones from the 1960's [B][COLOR=#008000] ON[/COLOR] [COLOR=#ff0000] OFF[/COLOR] [/B]New ones [B][COLOR=#ff0000] ON[/COLOR] [COLOR=#008000]OFF [/COLOR][/B] And those old MCBs with the dolly down for ON and up for OFF , you gotta what out for them babies .
