Do you make these errors when using high-potential (hi-pot) testers or insulation resistance testers? Using without isolating first. The hi-pot injects a high voltage into cabling. Normally, you isolate a circuit to protect yourself from the premises source. In this case, you isolate the circuit to protect others (and connected equipment) from your portable source. Isolating the cable at one end only. You must isolate it at each end, else you're providing ...

Hypothesis: insulation resistance testers has a z
