Wire Sizes
Use 105°C-rated wiring. Wire sizes for grounding (earthing) and power
connections are dictated by the terminal blocks and expected load
currents. Use the following table as a guide in selecting wire sizes.
Refer to
SEL Application Note AN2014-08
for wiring and termination
guidance. Strip the wires 8 mm (0.31 in) for termination and
installation.
