The values in this table are valid only if the PE cable and AC power cable use the same
conductor material. If this is not so, the cross-sectional area of the PE cable conductor is to
be determined in a manner which produces a conductance equivalent to that which results
from the application of this table.
Installing the PE Cable
Step 1 Crimp an OT terminal.
Step 2 Secure the PE cable using the ground screw.
