Cable capacities
• All calculations allow for a 45% space factor.
As there can be differences between data cable sizes,
Marshall-Tufflex recommend that cable dimensions are
confirmedwith themanufacturing company.
Compartments 1 & 3 = 2812mm² (each) total area
Compartments 1 & 3 = 1265mm² (each) 45% space factor
Compartment 2 = 760mm² total area (with box)
Compartment 2 = 342mm² 45% space factor (with box)
System 130 trunking
130 x 63mm
System 170 trunking
170 x 63mm
Compartments 1 & 3 = 1585mm² (each) total area
Compartments 1 & 3 = 760mm² (each) 45% space factor
Compartment 2 = 713mm² total area (with box)
Compartment 2 = 342mm² 45% space factor (with box)
Dimensions
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.
