Supply to Summerhouse - volt drop

Or join L to N at the board and measure R1+Rn directly at the particular point on the ring. Of course, the other loads on the ring and their distribution will affect the VD, so maybe not so easy after all.

Still not really following you HandySparks, but I'll keep figuring and I'm sure I'll get it eventually, cheers.

You will get a phone call soon asking if you can come back as other electrician not come back to complete

Think I might just say get stuffed, I'm not bitter! Didn't like the last bit in their phone call, implying I was trying to rip them orff. They did name the other spark, so I've no doubt he'll wire up their Summer House; hope he checks for continuity. Otherwise they might be sat in it one day, to see smoke coming from their house.

Time to move on
