Specifications and Installation Guide

To comply with wiring regulations, the installer shall ensure that the trunking is not overfilled and acceptable pressure is applied to the cables.
In order to do this, the installer shall not exceed the 45% space factor given in the rigs.
The 45% space factor means that the total cross-sectional area of all cables shall not be greater than 45% of the cross-sectional area of the trunking.

Choosing Correct Trunking Dimensions

For each cable being used, obtain the appropriate factor from ‘ cable sizes and factors ’ table.
Sum all these cable factors and compare the result to the ‘ trunking sizes and capacity factor ’ table.
The minimum size of trunking that can be used is that size having a factor equal to, or greater than the sum of all trunking capacity factors.
