Need to make a circuit that will cut off power if no ground wire is detected? |
I need to make a simple circuit that will make a 3V line active when the ground wire is not present. My surge protector has this ground wire detection thing so I know its possible. I just need a circuit to trip two 3V relay's as soon as the ground wire is not detected so they can cut off the neutral and live wires. It is not a simple circuit. It involves electronic sensing of the potential difference between the neutral and the ground and then must open the circuit by removing power to the relays and allow them to open. |
