We have a new Hotpoint oven to install SI4 854 PIX. Old oven was 2.8kW Neff hard wired into dedicated circuit with its own breaker switch on wall. However, new oven, with pyrolytic cleaner, is 3.65 kW, rated but comes with 13Amp plug and lighter gauge wiring. I was going to plug in myself but clearly I need a sparky to convert hard wired socket to plug socket. However, in any case, this seems wrong - surely this requires 16A fuse and heavier duty wiring?
