Because if I use the one from the N bar I will actually test just that short piece of cable and through the...

    unidentified circuit

    did a cu upgrade on a house the other day but could not identify 1 16a radial circuit. The old board was not labelled and the owners were no help. I searched high and low for it and the house was also full of junk which didn't help. What do others do in this situation ?
