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 confirmed
with themanufacturing company.
Compartments 1, 3, 4 & 6 = 892mm² (each) total area
Compartments 1, 3, 4 & 6 = 401mm² (each) 45% space factor
Compartments 2 & 5 = 760mm² total area (with box)
Compartments 2 & 5= 342mm² 45% space factor (with box)
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)

*Check with manufacturer for typical values.
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.
