In some types of fixtures, both wires will be the same color. When I turned on the power, the GFCI's LED lit, but I couldn't reset the. An overload/short/fault will still trip this circuit breaker…. There are two black wires, and one which is. Since the wires were reversed, electricity was still flowing out of the outlet and you completed the circuit with your knife. The physical set-up reflects the M-connection, as you guessed, so to see "what happens" with CW rotation, connect the live and neutral as the two connections going up along the ~ in the M connection drawing. #3. There should also have been a neutral but many people omit this.The stat was only working as an on/off switch so it wouldn't have matered which way round the wires were. The reasons for this can vary but it could be from a shared neutral in another circuit or it could be from a multi wire branch circuit (MWBC). Also in some older appliances, the grounded (neutral) conductor was bonded to the chassis of the device. In most cases, the circuit will break and one of the wires may burn. What happens if you switch live and neutral? If you bond the neural+earth bond in two locations, you now have a parallel current path between the genset/inverter and the main AC panel. Live, neutral,and earth, are labels that are used to convey some information on the use of each wire. Similarly, you may ask, what happens if hot and neutral are reversed? You are correct in thinking that in a typical two wire AC loop/circuit, both wires carry the same amount of current (amps). For example, a switch may only turn on/off the live wire. unphased, Aug 19, 2018. The wires. This wire is commonly referred to as the neutral wire, and it should always be white. The Neutral of your service is connected to Earth ground at the service panel. This should be the only point the ground comes in contact with the neutral. 23,957. At any given time, whatever current flows through the live wire, an equal amount (*note 2) flows in the opposite direction through the neutral wire. These make a nice alternative for those wanting a simpler time with their T8 LED fixtures for tube lights. The description suggests the fan's Live and Neutral have been taken from the cable to the switch and the fan's Switched Live taken from Permanent Live. When the switch is OFF the fan is supplied with a Neutral via the lamp and Live from the Live to the switch. Neutral is grounded in or outside the home at the distribution transformer and ground is a safety wire that also carries Line filter cap currents up to 0.5 mA each.
