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.
Figure 5-7 Connecting a PE cable
Step 3 (Optional) To enhance the corrosion resistance of a ground terminal, apply silica
gel or paint around the terminal.
