This tool provides a preliminary current-carrying-capacity estimate. Final cable ampacity must be verified using the applicable project standard and the actual cable construction, installation arrangement, thermal environment, bonding system, armour or metallic sheath losses, soil conditions and other relevant engineering parameters.
Large MV and HV cables, heavily grouped circuits and critical underground installations should be evaluated using a complete thermal calculation based on actual project data.
Send XWA the voltage class, conductor size, load current, installation method, route length, ambient or soil conditions and required standard for a project-specific cable recommendation.
