I am in need of advice on the wiring for a ground connected indicator lamp for a control panel.The power supplied to the cabinet will be 120VAC with the common connected to the ground bar in the cabinet. Could someone be kind enough to point me in the proper direction. I have an example for an ungrounded common that uses two indicator lamps, but I do not think it will work for the grounded common system.
 
buy a ground fault detector circuit, it has relay outputs when the isolation is failing, but can be used other way around same.
