In this video we test a bunch of older and newer GFCI (Ground Fault Circuit Interrupter) devices that are typical of those found in Canadian and American homes.
We look at how sensitive they are - how few mA of current it takes them to trip and how quickly they trip. We also compere older ones to newer ones - are the older one (still) effective. We also look at the power consumed by these devices.
