In the UK we seem to be having a problem with what items are called I wonder if the same is true in USA? Examples. Transformer we traditionally considered as being a wire wound device to step up or down or isolate. Today we are finding inverters being called transformers and when advising people if they can fit LED lights to extra low voltage systems it becomes hard to explain what step down lumps will and will not allow use of LED. Low Voltage we define this as AC between 100 - 1000 volts but we get a lot of extra low voltage stuff marked as low voltage. Ballast we consider this as a special choke to run a florescent tube from again wire wound seeing now inverters and switch mode power supplies also called ballast. Live and Line also getting mixed up. We earth one of the supply wires as the supply transformer and we call that wire neutral will also have the phase wires and with single phase we call it line. Both line and neutral are both called live. However finding a lot of equipment with the Line wire called Live. Our 110 volt is either 55-0-55 or 63-0-63 depending if from single or three phase source. With this split phase supply we should have Line 1 and Line 2 and colours should be Brown - Black or Grey - Green/Yellow but when we open any appliance we find Brown - Blue - Green/Yellow and terminals marked L and N not L1 and L2. Although in USA you use a sort of English you I know use different words and with electrics also have different words like our earth = your ground not sure what you call bonding? So question is are you also having a problem with descriptions? With some areas like welding we have transformer or inverter the latter being a HF unit but with lighting we are lucky is some one includes the word electronic at least you have a good idea what it is if called an electronic transformer but not what I would call it. Thanks Eric

I was considering buying a Circuit Breaker Finder, but then Ideal told me if I plugged their transmitter into a non-working outlet, it wouldn't work because the transmitter signal needs to go piggyback on the circuit signal. What methods do you all use to find the breaker at the panel? I assume there's a power off Circuit Breaker Finder, but guessing it's a lot more expensive? What I have been doing after I figure out which breaker it is... remove the HOT and Neutral from the breaker, then hook-up Fluke Networks Pro 3000 (handheld) Tone Generator & Probe in order to identify all the outlets on the circuit. Then I plug in a 3-prong circuit tester (with the three lights indicating OPEN Neutral, Open HOT, HOT/Ground Reverse, etc.) on each receptacle on that circuit. Then I determine where best to start looking first, according to the pattern of ON or OFF, or partially lit testers I observe. Better methods gladly accepted!
