Cable Sizing Calculation Record (Excel)
Free download · Excel (.xlsx)
Every cable sizing calculation should be documented in a structured, auditable format — not buried in emails or scribbled on paper. This Excel template provides a complete cable sizing record with columns for Circuit Reference, Load Description, Load kW/kVA, Power Factor, Voltage, Phases, Load Current, Installation Method, Ambient Temperature Derating, Grouping Derating, Overall Derating Factor, Derated Current, Selected Cable Size (mm²), Cable Type, Current Rating, Cable Length, Voltage Drop (V and %), Short-Circuit Withstand, Pass/Fail Status, Standard Reference, and Notes. Conditional formatting highlights any circuit that fails voltage drop or current rating checks. Use this as your project's permanent cable sizing register and cross-reference with ECalPro's cable sizing calculator for verified results.

Frequently Asked Questions
What derating factors are included?
The template includes columns for ambient temperature derating, grouping derating, and an overall derating factor (product of all applicable factors). Add additional columns for soil resistivity or depth of burial derating if required for your installation.
Can I use this for multiple standards?
Yes. The Standard Reference column lets you specify which standard applies to each circuit. The template structure works for IEC 60364, BS 7671, AS/NZS 3008, and NEC — just adjust the derating factor references.
Does this replace proper cable sizing calculations?
This is a record template for documenting your calculations, not a calculation tool. Use ECalPro's cable sizing calculator for standards-compliant results, then transfer the verified values to this record.
