When carrying out periodic inspections we are always asked whether we have to turn off circuits with critical equipment such as servers. My stock answer is yes but I am told there is a method/meter that can carry out certain tests whilst the circuit remains live without disruption/damage to equipment. Without sounding stupid (I hope) I have never heard of this before but the information came from a reputable source and I wondered if anyone could shed some light.
