Could someone please clarify if my oven wiring is correct as I’m a complete novice. 3.5kw fan oven on own circuit. Oven in fuse box says B32. There’s a dedicated oven switch on wall near oven. Underneath cooker is a double plug socket to which the to oven wire is plugged in. Is this correct for 3.5kw oven. The oven didn’t come with plug attached to oven wire.
