Does the current edition of BS7671 actually say that plain green may not be used as well as green/yellow?just as long as the insulation isn't green / yellow ( or green )
... just as long as the insulation ... and the sheath is not the same colour as the insulation. ( so it can be clearly seen as insulation and sheath being separate material ).

Is it a rule that sheath and insulation must be different colours ? Maybe not but as they have to be leaid separately when the cable is manufactured having sifferent colours would be a lot easier.Is that now an actual rule?
