To determine cable capacity, select
the size of the cable required and its
corresponding cable factor from the
table. Divide the compartment area
figure (with or without 45% space
factor) with the cable factor figure to
achieve cable capacity.
Note:
When 30mm deep accessory
boxes are installed in MTRS100,
MTRS100/50 and DTR1, reduce the
area by 2600²mm.
