[QUOTE="martinxxxxxx, post: 217754, member: 6454"] 510.2 Every item of equipment shall be selected and erected so as to allow compliance with the regulations stated in this chapter and the relevant regulations in other parts of BS 7671 and shall take account of manufacturers' instructions. 624Y Twin & Earth PVC Cable BS6004 A05VVH4-U Standard: BS6004 Electric cables. PVC insulated, nonarmoured cables for voltages up to and including 450/750V, for electric power, lighting and internal wiring. Clearly when looking at the data when they say "and internal wiring" it means should only be used internal which raises the question what should be done about it when found external? Should this cable replaced FOC as it should not have been used here? We need as practising electricians to get a really clear understanding of this very basic and fundamental issue to our work. I for one will be finding out from the manufacturers whether they are clearly saying it is not to be used externally. If they do then it would be a contravention of the reg above. If we could get the facts here it would accomplish something important. I have always thought that it was a big no no for outside, but a clear reason needs to be established to remove the need for further debate on this matter. Martin [/QUOTE]
