• Conduct leakage current measurement between enclosure and enclosure
using two ungrounded locations on the enclosure.
• The terminal block is not used for internally powered equipment, although
power must be supplied to [LINE IN] by a grounded two-plug power cord.
• When the protective earth conductor is disconnected (single fault), a protec-
