PFC TESTING – PROSPECTIVE FAULT CURRENT- DIFFERENCES BETWEEN SINGLE PHASE AND THREE PHASE METHODS

In this LearnElectrics video we will look at the differences between the single phase and three phase testing of prospective fault current. We are frequently asked questions about the differences and have included things like … What is PFC? Is PEFC the same as PFC? Just what is PSCC? And how can I find 3 phase PFC with my meter So in this video will put some of those questions under the spotlight and look at things like … Why do we want to test it anyway? If there are differences, then what is the reason Why have so many initials And. Once we have some numbers … which ones do we use. To view all of our videos type in LearnElectrics all one word into the YouTube search bar. This is video No.173 on our YouTube channel where we have videos on a wide range of electrical topics.
