Cable Size Input Checker

Compare two nominal conductor areas and check whether the project brief contains the inputs needed for cable engineering. The area ratio is not an ampacity or voltage-drop approval.

Candidate areas

Candidate A (mm²)

Candidate B (mm²)

Design current (A)

Engineering inputs

One-way route length (m)

Voltage-drop limit (%)

Ambient temperature (°C)

Installation method

Sizing brief status

Enter two candidate areas and the project inputs.

Final cable size still requires the governing standard, ampacity, derating, voltage drop, installation method and termination review.
