How to use
1. Select the Default wire spec. This will be used only for newly added standard wires, not for wires already in the list.
2. Click Add wire to add normal single-core wires. You can then change the spec, size, and quantity as needed
3. Click Add MC/TP to add multicores (MC) or twisted-pairs (TP). After selecting the spec, the calculator will identify it as MC or TP automatically.
4. Click Add Coax to add coaxial cables.
5. Adjust the quantity of each row with the + / − buttons or by typing a value directly.
6. Enable Future-proofing when sizing a new harness that may require later changes, such as new vehicle features, optional equipment, or additional electrical content after initial release. For example, 0.20 = +20% additional bundle Cross Sectional Area.
7. Click Calculate to generate the estimated Nominal bundle cross-sectional area, Nominal bundle OD, and a cross-section visual.
8. Click Reset to clear all rows and start again.
