Auto Cable Containment Sizing

Calculate cable containment capacity quickly and clearly.

Cable Containment Sizing Pro is a practical engineering tool for electrical engineers, consultants, technicians, electricians, solar professionals and students. It helps estimate cable occupancy and select suitable containment sizes using finished cable outside-diameter data and IEC-aligned geometric checks.

KEY FEATURES

• Quick Count for identical cables

• Mixed Cable Fill for combined cable schedules

• Cable tray, cable ladder, trunking, conduit and underground duct calculations

• Area-fill, physical-packing and single-layer calculation methods

• PASS, FAIL and VERIFY result guidance

• Automatic containment size recommendations

• Malaysia-common and international industrial size ranges

• Millimetre and inch display

• Searchable cable diameter library

• Copper and aluminium cable records

• Multiple cable families, core configurations and manufacturers

• Save or share results as JPEG

• Preview and save professional PDF reports

• Light and unlockable dark themes

QUICK COUNT

Select a cable and containment size to calculate the maximum number of complete identical cables that can fit. Enter the required cable quantity to assess remaining capacity and PASS or FAIL status.

MIXED CABLE FILL

Build a cable schedule containing different cable types and quantities. The app calculates:

• Actual containment occupancy

• Design utilization

• Remaining capacity

• Total cable quantity

• Cable occupied area

• Physical row-packing status where applicable

• Recommended larger containment options

CABLE DATABASE

Search cables using manufacturer, cable family, conductor material, number of cores, conductor size and finished outside diameter. Occupancy calculations use the complete cable outside diameter rather than conductor cross-sectional area alone.

ENGINEERING GUIDANCE

Built-in information buttons explain the calculation basis, formulas, worked examples, reference values and result interpretation. Editable project settings include fill limit, future spare reserve and cable spacing.

REPORT EXPORT

Create a clean engineering summary containing:

• Containment type and dimensions

• Calculation method

• Project fill limit

• PASS, FAIL or VERIFY status

• Occupancy and utilization results

• Cable schedule and outside diameters

• Containment layout visual

• Important assumptions and verification notes

IMPORTANT

This app is a design-assist calculator and does not replace professional engineering judgement, manufacturer instructions or project-specific requirements. Always verify actual cable outside diameters, clear containment dimensions, bend radius, pulling limits, grouping, heat dissipation, segregation, support loading and applicable local regulations before final construction or submission.
