Twin Plus aluminium – continued 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.
Twin Plus trunking – with accessory box
Compartment 1 (total area) = 4755mm²
Compartment 2 (total area) = 2431mm² with box
Compartment 2 (45% space factor) = 1094mm²
(compartment 1 and 2 are reversible)
