Tutorial and tips for fault finding polarity. Feel free to support me @ https://buymeacoffee.com/the_EA Error: 7:46 Me testing the phase sequence of the 3Phase outlet. The reason I had a reading was due to my main switch being switched on and having my phases bridged on the Lineside . Once I switched off my main switch at 8:56 I was able to test individually Red to L! White to L2 Blue to L3. Sorry I'm not perfect guys I had a bit of a DohL moment there. Two ways to test Polarity: Individually test: A-A N-N E-E L1-L1 L2-L2 L3-L3 using continuity method. Use Resistance leads -If you are using Trailing leads remember to test the resistance of your trailing lead and incorporate that trailing lead resistance into your expected resistance reading for each combination your testing.
