When power is sent to a home it comes in as 240v split by the center tap of the pole transformer, giving 120v on either side. Is there any way to determine which side of the center tap a particular outlet or other
120v device is connected, other than tracing wires and opening the breaker box? I'm mostly referring to using some sort of test gadget.I'm asking this because I have a device that sends a signal thru the power lines and I discovered that it only operates if the transmitter and receiver are on the same side of the center tap. This is not that hard to determine if it's in the same building, but I'm running to another building on the same electrical system, but the wires are impossible to trace visually, since they are an overhead twisted triplex cable.
Short of physically disconnecting one leg of the mains, there dont seem to be any other method, unless there is some tester which can determine it. I'd prefer having to disconnect the mains, which would require pulling the meter and all of that.....
Anyone???
