Ac Plug Circuit Checker Checker
To demonstrate AC circuit checker.
AC plug circuit checker with "fixed" multiple outlet box.
The multiple outlet box has been "fixed" so that each different kind of wiring error has been introduced to one of the sockets, including (1) open ground, (2) open hot, (3) hot and ground reversed, (4) hot and neutral reversed, and (5) correct wiring. The response of the circuit checker to each type of error can be seen by plugging it in. Plugging this multiple outlet box into a wall socket will not blow a fuse.
