      This is a plug, not an outlet; and it shorts the live + neutral pins together. There is no ground pin present, though a wire labeled ground is also being shorted to the live+neutral pins. (basing ‘pins’ on shape/colour and ignoring that at least one is in the wrong position)

      If this doesn’t immediately trip the breaker when plugged in, it’s because you have an open neutral; and now whatever’s on the end of that ground wire (typically exposed metal) is live.

        The live and neutral pins are wired together, so there’s not really a reason for the power to travel to that ground wire. Unless the path to the ground of the device, and then from there to actual ground, is shorter, then nothing will flow that way. It’s absolutely not safe, but a number of other factors would need to be present before it were deadly.

          Unless the path to the ground of the device, and then from there to actual ground, is shorter, then nothing will flow that way.

          That’s not true. Electricity will take all available paths to return to ground, with current flow relative to the resistance present. In other words, two low resistance paths will share similar amounts of current when both are connected to power.

          If you were touching anything connected to that ‘ground’ wire while also connected to a true ground yourself; you could receive a harmful shock from plugging this in, even with a breaker in-line and successfully tripping. A GFCI device should prevent that shock, but a regular breaker will not trip fast enough.

            True actually. If this were the plug for a washing machine, and you were touching it and the tap for the water inlet, you would definitely get shocked still. Edit: The washing machine itself also wouldn’t generally have a connection to ground that way, as they usually use plastic hoses.

              I’m not sure which of you is correct here but it’s fascinating how confidently people on the Internet will make statements. I’m sure one of you has earned that confidence but I’ll never know which one. Sadly, the other person should question their life choices pretty hard.

                Unless I’m reading this thread incorrectly; I believe Norah was mistaken in the comment I replied to, but came around with my explanation.

                The mindset of ‘electricity takes the path of least resistance’ is really quite common and was actually taught in my highschool; but it’s rather misunderstood, if not outright wrong.

      I wouldn’t say connecting the ground wire of an appliance to the hot side of an outlet is very safe.

      This picture doesn’t show how to wire socket, but now to wire a plug. The wire that’s labeled ground is actually attached to live connector, although I guess that doesn’t matter as live and neutral are shorted by white wire.

              No, it’s not the only wire in the circuit. If that plug is plugged into an outlet, then the hot live wire is coming into the circuit at the pin labelled live, and connecting to the ground wire of the device. That ground wire is usually connected to the metal frame of an appliance. Because of the white wire connecting the live and neutral pins together, it’s going to immediately flow back to the breaker box. However, if for whatever reason the path from the ground of the device to actual ground is shorter, then the electricity will flow through the device. It is possible for a person to be in the path to ground. The way this is wired might also circumnavigate an RCD, preventing the safety switch from operating correctly.

                An RCD measures the difference in current flow between the phase and neutral, so it will trip in this scenario. An alternative path to earth is precisely what they’re designed to detect.

                  Ah yeah, you’re right, my mistake. It’s wild to me as an Aussie that they aren’t universal in the States. Plenty of houses (or outlets?) don’t have them IIRC?

                    Plenty of old houses still don’t have them in Australia and NZ, but they’re required on power circuits in new builds.

                    As they should be, they’re an incredible technology.

                  It should; but it’s also important to note breakers are not intended to prevent electric shocks, they are intended to protect the wiring within your walls.

                  The time in between this being plugged in and the relevant breaker tripping IS enough time to receive a harmful shock from that ‘ground’ wire. Preventing this is the purpose of GFCI devices.

                    Assuming everything else is in good working order, the fault current would probably be enough to trip the breaker in a similar time frame to how fast a GFCI would react.

                    But, if the owner of the house is asking AI for electrical advice, it’s entirely possible they’ve fucked up wiring the socket as well.

        Connecting the earth wire, which goes to the metal casing of the appliance, directly to phase definitely isn’t safe.

          And where does phase go to or come from? The picture shows a short of piece of wire labelled “phase” but that doesn’t magically make an otherwise unconnected piece of wire anything active. If labelling anything “phase” could produce energy, boy would my energy bill go down fast 😂

          I keep to my statement: The pic shows a completely dead “circuit”.

            This is a plug, which you plug into a socket, which is where the leccy comes from.

            Of course the circuit is dead, it’s not plugged in.
