hardwiring a single fitted moffat oven took off back but can only find male spade connectors and the wire going to the elements which a v thin. Will be going from 10mm wire in outlet use 6mm to oven with female spade conections. Circuit for cooker is on 32amp fuse oven 2.1kw. Is this ok and am i really meant to conect to that seemingly fragile circuit with spade connections and 6mm?
