Cable calculations

Hi guys i wanted to calculate the maximum run when spuring of a ring final circuit is there any equations or is it just as simple as calculating VD to the furthest point in the ring and then VD to the end of the spur. The reason for the question is I want to spur of an existing socket using a 10meter run of 2.5 for an outside socket. Just want to Double check it’s sufficient 


thanks guys

  • It's the position and type of RCD, a RCD socket outlet that's not listed in the regs and it's at the end of the circuit rather than the start. 


    It will not be particularly dangerous, but there's issues with doing it that way. 


    I suspect most electricians would consider doing it that way.
