[QUOTE="SPECIAL LOCATION, post: 193416, member: 250"] Your points (7) & (8) are ONLY true if the 1000watts is at the end of the cable 40m.. IF 4.34A is NOT being drawn at the 40m length then those calcs are irrelevant! Diversity can be applied to single circuits... See Paragraph 3 page 95 One site Guide! And most certainly lighting circuits, (of all the various type of circuit) are very much a circuit where diversity is a VERY relevant factor. Which is why as Soulman states.. Table 7.1 page 44 On site guide suggests a 5A 3036 on 1.0mm cable can be up to 70+ meters long.. (5A @ 230v is >1000w!!!!) ;) [/QUOTE]
