Also... Bear in mind the largest Breaker (MCB) is 40/50A. You may need a 'Type C' (Instead of the usual 'Type B') MCB/Breaker to act as a delay to avoid nuisance tripping from the In-rush of current during 'start up' Mark - Fuse Electrical Services

That's a beast of a cooker - 'Pyrolithic' ? 10mm in a short run maybe. I'm curious to see the size of the terminals on the back of the cooker. If someone was to place insulation on top of the cable inadvertently, during Xmas Day cooking you could have a a house fire. That's a massive draw for a cooker, the largest I've seen was double oven and Induction plate (Range style) and that was at the limit of 10mm @ 60+amps. Bear in mind most/some houses only have a 60A supply! You may need the distributor to upgrade you main fuse also to 80A/100A.

Given that you've asked for the cable for a 16kW cooker a 10mm will be needed, allowing for diversity it only just falls outside the standard 6mm T&E size. Cooker manufacturers IE: Range master recommend a 10mm T&E. Hope this helps Marcus

Allowing for diversity factors, 6-10mm Twin and Earth cable should be fine Thanks, Richard Baldwin (Trydanwyr Bright Spark Electricians)

Hi David, If the length of the run is less than 20 meters and the cable is going to be clipped onto a wall or ceiling, a 3 core 10mm2 armored cable (XLPE) should be fine for that kind of load. If the length is longer or the cable is buried, then you better use a 16mm2 to be on the safe side and a cable suitable to be buried.

David, For an exact answer I need to know how long the cable will be and how it will be installed Ie: in trunking, through and insulated wall or clipped direct. Kind regards, Ben Burdass
