11,5kW range cooker

[Stever_777]

Hi guys, I'm pricing a job, it's an extension for a new kitchen and dining area. There' s a 11,5kW range cooker going in, dishwasher, cooker hood, fridge freezer, 5 DSO's, and 2 lighting points with intermediate switching. Central heating is combi. The run to cooker is about 24m. Would I be right in saying that I'll need a 10mm T & E and 50A MCB for the cooker?The DNO's BS 1361 fuse is 60A and it looks like the tails are 16mm. Anything from you more experienced guys what I should take into consideration while pricing?Thanks

37A on 2.5mm.a tad optimistic. or is it the shower maker that's conning .

In all fairness. I doubt the shower was ever run at much more than half of it's potential output.

Distance was only 8 metres from board to shower. Clipped direct from CU then ran in loft space. No insulation.
