How An Isolated Dim Bulb Tester Works (Current Limited Isolation Transformer And VARIAC)

In this video Erik discusses how an isolated dim bulb tester (current limited isolation transformer and VARIAC) works and how to electrically configure the main components. Are there certain configurations that work better than others? Let's find out. Also, what to watch out for when you buy certain types of "isolation transformers" that can cause safety problems. Erik shows the isolation transformer, variac, and dim bulb current limiting he uses on his workbench with a demonstration when a short circuit happens.
