You must find the main power feed wire to your fuse panel, disconnect it at the source and place the positive amp meter lead where you lifted that wire. Place the negative amp meter lead on the wire you lifted. Now all the current will be flowing through your amp meter.Fahr said:Thanks Vince
What I need to know is, once the Ampmeter is set to the correct Amperage , which of the probes are used , is is there one across the main fuse ie posative , neutral either side - across ?
thank you for the assistance
You cannot figure amperage with just a voltage measurement you must have one other factor in the formula as follows.Fahr said:Can a voltage measurement and a calculation arrive back at Amperage.
In industry those are known as "CT's" (current transducers) and are commonly used on large motors. The CT is placed on the "T" leads of the motor to measure amperage. Three phase motors will typically have one on each phase leg.75gmck25 said:Another option is one of the inductance ammeters, where the meter probes are shaped like two short arcs, and you just surround the wire where you want to measure amperage. They are more expensive meters, but you don't have to disconnect any wires to use them.
