Check the comments of the original post for the stupidity.
For those of you without an electrical background, the diagram shows the protective earth connected directly to phase, with phase and neutral also joined.
Correctly wired, this would be a three pin plug, with the earth wire connected to the earth pin in the plug, with the other end connected to the metal casing of the appliance. This is a critical safety feature, which will cause the circuit protection to trip in the event a phase wire contacts the metal of whatever this is connected to.
If this was actually done, the most likely outcome is it would trip a circuit breaker, but if the neutral was broken, it would connect phase directly to the casing, and likely electrocute someone.
I don’t? Please, do go on. I am interested to know how all my appliances apparently work by magic.
Well, yes, someone wires the plugs at the appliance cord factory, but unless you work in appliance cord manufacturing it’s typically not the appliance user. And yes, there are exceptions, such as installing some heavy appliances or replacing damaged plugs, but that shouldn’t be typical for “all” of someone’s appliances.
I’m interested to know how you are wiring plugs… and why. They are sold pre wired in my area. Are they not in yours?
North american plugs are not serviceable like british ones. The contacts are molded in plastic at the factory.
Opening a plug to service the wires is not possible. They don’t open, nor do the plugs have fuses.
Serviceable, sure, but they literally make replacement plugs that you would do yourself, in which case, knowing how to wire them is a whole, you know, thing.
