Clamp ons are realy made for the mains panel, I made up a 12"
intermediate plug with 3 separate wires for cheching apliances, But for
accuracy to 0.01A Digital you need to go to an electric supply house HD
etc models go only to 0.1A unless you get an expensive unit. 0.01A
digital is good for finding shorts , many houses loose to ground and
people dont know it.
