Terminating load wiring.
Note that numbering is
always from left to right, ie:
Earth 1–12, Neutral 1–12,
Phase 1–12. The same rule
applies to 3x10kW and
6x5kW Power Assemblies.
Tip:
It's easier to fit the
bottom Power
Assembly first,
terminate the load
wiring, then fit the
middle Power
Assembly, and so on.
