Let's work on our terminology for a minute: Voltage: a measure of electromotive force. By 'carrying a voltage' is meant the presence or absence of a voltage on the surface of a conductor. Current: a measure of the time rate flow of an electrical charge. By 'carrying a current' is meant the presence or absence of a flow of electrical charge through a conductor. To check for voltage on a conductor, connect one lead of your voltmeter to electrical ground which means that terminal which is at ground potential. Connect the other lead of your voltmeter to the conductor being tested for the presence of voltage. Read the value of voltage on the voltmeter. To check for current through a conductor, encircle the conductor with your clamp-on ampmeter or, if no such instrument is available, open the circuit, then close it again using your ampmeter or a suitable shunt. Ok. Now what I mean when I say that neutrals do not carry significant voltage is that, without opening the circuit, if you check for the presence of voltage on a neutral, you should not get a significant reading, regardless of whether the circuit is carrying an electrical load or not. All clear? Marc
