CA 2216201
A self contained electrical status indicator that can indicate whether a load isoperating or not, it requires no batteries and uses a current transformer with alight to indicate current and another light to indicate voltage. The nature of it's design allows a user to safely connect it between an alternating current (AC) source and an electrical load utilizing plugs and sockets intended for that loadwithin seconds. It can determine whether or not a load is operating as expected and if it isn't, the device conveys the general nature about where the problem lies. The device can be left connected between the source and the load for as long as desired or it can be used temporarily. It runs on the power available from the circuit to which it is connected. One of it's two lights indicates whether or not supply voltage exists and the other indicates whether or not the load is drawingcurrent. Since the supply voltage determines the overall operation of the deviceand of the load any problems with the supply will naturally have to be overcome first. Only then can any problems in the rest of the circuit be addressed. The electrical status indicator's output can be consulted once again in this case.
