Maybe taffy was thinking that way too which would explain why he said 26a could be drawn, however just going by the ops drawing there is nothing to suggest it would be looped through so in my opinion it was worth 5 pages just to clarify the point that,
yes his circuit is correct providing he wires from the load side of the fcu and not looping from the feed.
Everybody happy with the clarification now?
First drawing isn't wrong though as its designed on 6amp max load, the OP should label up max fuse size that should be replaced if it blows in future. But on saying that i do see where Taffy is coming from now and i do agree that if the fuses were replaced with 13a ones then this would show an overload of the cable.
Interesting........
Just out of interest, what exactly is the the danger in adding 2 3A FCU to the ring? If situation ever arose that I needed to do it I'd be more than fine with it. I'm sure the OP is lost now as to what to do after 66+ posts, but either option initially posted seems fine to me, the 2nd is a little overkill.
If we are all worried about what the incompetent person may do after us then 32Amp ring are out, may as well do 10Amp radial to cover for them. Don't want to have them adding a shower to the ring after all! I don't care much what someone adds after me, that's their problem. Common sense seems to have long gone here.
At no point have I said Pic 1 was dangerous, just not compliant. Guess the acid test is if this question was in an exam what would your answer be Pic 1 or Pic 2 ? . And this nonsense about the boiler SFCU being fed from the fused side of the 1st SFCU is just folks back pedaling. Or does anyone think its a good idea to have the boiler turn off when you turn the light off?
Not back pedalling at all. I made a simple mistake of thinking the whole circuit was fused at 3a. I quickly realised my mistake and then admitted you was right.
