Banggood sent me this Mastech MS5902 Automatic Circuit Breaker Finder to take a look at.

In addition to tracing wiring and identifying circuit breakers, it can also verify that outlets are wired correctly and can test GFCIs for correct operation.

Join me while I run it through it's paces and take a look what's inside.

If you want one after watching the video, here's the link:
