SPINE WIRING
• Wire Spines in 1.5 mm
2
or 2.5 mm
2
T & E
For a typically loaded system, the following spine lengths apply:
• Max. length for a single spine using 1.5 mm
2
cable = 150 m
• Max. length for a single spine using 2.5 mm
2
cable = 250 m
• Max. length of all spines + limbs = 750 m.
The above are general rules of thumb, if required refer to
Pages 10 & 11 for more specific wiring details/calculator chart.
