$$I_adjusted = I_base \times K_temp \times K_group \times K_soil \times K_insulation$$ factors affecting cable rating

Cable rating refers to the maximum current-carrying capacity (ampacity) of an electrical cable under specific operating conditions without exceeding its temperature rating. Correctly determining cable ratings is critical for safety, system reliability, and preventing insulation degradation or fire. This report outlines the primary factors that influence cable rating, based on electrical, thermal, and environmental principles. End of report $$I_adjusted = I_base \times K_temp

The tool flags a warning: "Rating reduced by 65%. Cable is now undersized for your 200A load." It suggests: "Upgrade to 185mm² or separate cables by 1 cable diameter to recover 25% capacity." The tool flags a warning: "Rating reduced by 65%
