Load carrying capacity

Step 1: Identify the insulation material

Start by selecting the insulation material of your cable from table 1, as this determines its load carrying capacity.

Example: CF5.10.12, (12G1.0). Insultation material is PVC

Step 2: Check the nominal cross-section

Find the load carrying capacity for the cable’s nominal cross-section based on the insulation material.

Example: CF5.10.12, (12G1.0). Insultation material is PVC. The load carrying capacity for PVC insulation at 1mm² is 15 [A]. So the load-carrying capacity in [A] so far is 15 [A]

Step 3: Consider the ambient temperature

Use table 2 to adjust the load carrying capacity based on your ambient temperature.

Example: CF5.10.12, (12G1.0). So far the cores are running at 15 [A] and the ambient temperature is 60°c. 15 x 0.50 = 7.5 [A]

Table 2: Conversion factors in case of varying ambient temperature

Step 4: Account for loaded cores

Multiply the result by the number of loaded cores to determine the final load carrying capacity.

Example: With this particular example we will say that only 10 of the cores are loaded.. 7.5 [A] x the number of loaded cores conversion factor.. 7.5 x 0.55 = 4.12 [A]
