| + | ====== How to check Phase, Neutral and Ground of AC Wiring Using a Multimeter ====== | ||
| + | |||
| + | I'm by no means an Electrical Engineer but from time to time I have to do your typical DC wiring and soldering. But AC is a completly different beast to me, since I rarely have to interact with it. | ||
| + | |||
| + | That's why this was done: so I can get this information quicker instead of burning stuff down and / or having 230V - or read that as 120V if you leave in ' | ||
| + | |||
| + | * With the Power Supply / Lamp / LIVE **(BE EXTRA CAREFUL)** | ||
| + | * Set the Multimeter to AC Volts | ||
| + | * Connect to 2 terminals | ||
| + | * If you connected Phase and Neutral = 230 Volts | ||
| + | * If you connected Phase and Earth = 230 Volts | ||
| + | * If you connected Neutral and Earth = 0 Volts | ||
| + | * So the same wire giving the 230 Volts reading will be the Phase (Live Wire) | ||
| + | * Now you should know which one is the Phase so | ||
| + | * Shut of Power Supply **(SHUT IT OFF)** | ||
| + | * Set meter to Ohms | ||
| + | * Connect between Earth and and another wire. If It reads 0 - or near - Ohms, that is Wire. | ||
