How do you know if a phase is neutral? The piece of wire that is connected to the tester by touching the tip of the tester to the phase. Touch the other end of it to the point you think may be neutral. (Be careful not to touch the conductor of the wire or the upper end of the tester while doing this action.)
What happens if I connect phase and neutral? When a live phase and neutral wires meet, a short circuit fault is created between source and load. Due to this short circuit, a high amount of current flows from all directions to this short circuit path as it has very low resistance.
What does neutral in electricity mean? Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.
What does Neutral do in 3 phase? A neutral wire allows the three phase system to use a higher voltage while still supporting lower voltage single phase appliances. In high voltage distribution situations it is common not to have a neutral wire as the loads can simply be connected between phases (phase-phase connection).
