• Wiring to the terminal block and to the small internal earth stud shall only be with the
stranded or solid copper conducitors size 0.75-2.5mm

• Wiring to the large external earth stud shall only be with stranded or solid copper
conductors size 1.5mm
2
to 6.0 mm

• Only one conductor shall be used to a terminal unless multiple conductors have been
joined in a suitable manner e.g. by a single insulated crimped bootlace ferrule
• Wiring to terminals shall be insulated for the appropriate voltage and this insulaton shall
extend to within at least 1mm of the metal of the terminal throat
• Tighten down the unused terminal block terminal
• Torque used terminal block terminals to 0.6 ± 0.1Nm
• Torque small internal earth stud to 1.2 ± 0.1Nm
• Torque large external earth stud to 2.0 ± 0.1Nm
• Ensure internal and external wiring does not cross over the terminal block terminals
