If a wired doorbell is connected as per manufacturers instructions and is powered by a 3A fused plug as an appliance, does it need inspection or certification?
i.e. what if the mains 2 wire power lead for the transformer (which steps down power to the bell wire circut) goes to a household 3 prong plug (no bell unit earth wire so earth not connected) which has a 3A fuse and is plugged into a wall socket and can optionally be removed from the socket or switched off just like a vacuum cleaner or a TV or something. The point being if the bell unit is not directly wired into the house circuit am I right in thinking that would count legally as an appliance and not need certification?
