Interesting point. I use AMTECH cable calculation programme. It states reference method 7 for your particular situation. Now I left my glasses at the caravan this weekend but I cant see ref method 7 in appendix 4. In any event I would be glad to calculate any circuit for you using the programme.
Just wondering, What is a reference method?. Is this like a Current carrying capacity Table, in various types of installations?.
Yes you look up the Schedule of installation methods table first (4A1), to get the Method No, then refer the method Number to the current carrying capacity tables, also taking into account various correction factors.
