Is there a reason to distinguish ground from neutral when it comes to electrical testing? If you need a reference for a voltage measurement, doesn't ground work just as well as neutral?
Not at all! Ground and neutral are supposed to be two separate things in an AC circuit, and so they can't be used interchangeably. In this short webinar excerpt, the Samurai breaks down what the difference is and why you should only ever use neutral in your AC voltage measurements.
This is exactly the kind of electrical know-how that we teach in the Core course over at the MST Academy. Bonus: A free Appliantology premium tech membership is included with your enrollment.
