As per a couple of previous threads am now at first fix stage and am thinking about testing,
Set up is tn-s,main income tails split through Henley into switch fuse isolater and 10mm 3 core sea out to (approx 20mtrs) Cu unit in man cave/pub
Never tested a unit so far from the origin that wasn’t a sub db, questions are is this still considered a sub board? Am I right in thinking I need to take ze at the origin before switch fuse isolator? As to take it at the Cu is not external? And if so what would I record on the sheet for the swa feeding the unit?
Hope that makes sense?
Thanks in advance as always
