Hi guys, just curious. I have a plastic electric kettle that has an earth lead in the flex. I can't see much point in it. It will trip the RCD in the event of an element insulation breakdown so there's some use there. Any thoughts?
Just a comment that's not specific to kettles, but goes to illustrate a point.
Many appliances contain components which, individually, might have different methods of protection against electric shock. The kettle you cite may well comprise a Class I element, with Class II (probably reinforced insulation) for the terminals and switching elements.
Similarly, a washing machine may well have a Class I element, Class I motor, Class II pump, and have an overall Class I construction with earthed metal body, although the bezel area being plastic may comprise various forms of Class II construction.
These consideraions are important for those inspecting the appliance for safety after repair or during regular workplace inspection and/or testing that we have in the UK.
