DIY Variac And Isolation Transformer Build Guide. Fire And Death Avoidance!!

A basic guide to building a simple Variac combined with an isolation transformer. Before watching this video, if you would like to find out how a transformer works in basic terms (which will help in understanding this video), there is a good explanation near the beginning of the following video here at 55 seconds in https://www.youtube.com/watch?v=yhuhPXFGb6M

Errata: The schematic diagram at 11:26 has a mistake in the text, the power switch and fuse is shown connected to the neutral wire they should be instead connected to the live wire. Plus the wiring diagram at 15:17 does not show the power switch at all.

Many thanks to Brooks in comments section. For giving the name of safety throw switch here is a link on more info on this nice looking bit of kit
