Yeah, after seeing both sides of that wall, i would expect one of my guys to have that done in an hour excluding a parts run if needed.

 

Yes, that seems about right.....but there is the RCD at the fuseboard along with enclosure, could have been a bit of an issue squeezing it in around the other fuses, without a picture of that it could well have taken an hour to id the circuit, nudge some other fuses sideways/up or down so everything fitted....
