The protocols for PAT Testing vary by appliance class: Class I – Single insulated wiring, which requires an earth connection for safety. If the appliance has no symbol on it, then it is to be treated as Class I for the purpose of testing. Class II – Double insulated wiring, The earth clamp is still connected during the insulation test.
The test is a means to qualify a device's ability to operate safely during rated electrical conditions. [1] If the current through a device under test is less than a specified limit at the required test potential and time duration, the device meets the dielectric withstand requirement.
In many countries the plug of a class 0 equipment is such that it cannot be inserted to grounded outlet like Schuko. The failure of such an equipment in a location where there are grounded equipment can cause fatal shock if one touches both. Any Class 1 equipment will act like a Class 0 equipment when connected to an ungrounded outlet.
