Not only the enclosure and insulation but also the internal circuits providing adequate capacitance discharge or backfeed protection.

We would all agree that mains is a hazardous energy source (or comprises a hazard). The equipment in question is provided with a suitable enclosure and fully complies with the applicable safety standard. We have a number of definitions for "hazard" from the various posted messages: anything potentially harmful potential for an action with adverse outcome something that can hurt you or do property damage potential source of harm Question: Does the mains within the equipment comprise a hazard?
