3-Wire Solid-Grounded Wye, 3-Element, Direct Connection

LINE LOAD

Fuse for N/- terminal required if its supply source is ungrounded Connect G terminal to ground for AC power source

When the common or star point of a 3-wire Wye system is grounded, the meter may be connected directly without using PTs, provided that the phase voltages are within the meter’s range.

VOLTS MODE = 4W-Wye
