The complete electrical design workspace for contractors. Cable sizing & cable check, transformer sizing & power factor correction, panel config, short circuit, grounding, motor control, lighting, meter sizing, cable tray, lightning protection, quotation with GBQ export, BOM & inventory linkage, terminal blocks, device log, drawing markup — all in one offline tool.
20+ modules covering the entire electrical design workflow.
Calculate cable cross-section, ampacity, voltage drop for any circuit.
Design distribution panels, breakers, buses, and circuit schedules.
Calculate fault current and verify breaker coordination, with thermal stability & peak current (dynamic / thermal) checks.
Design grounding systems, calculate earth resistance and electrode sizing.
Size motors, contactors, overload relays, and control circuits.
Calculate lighting loads, fixture counts, and lux levels, with standard illuminance & LPD check.
Size main breakers, buses, and service entrance equipment.
Design cable tray layouts, fill ratios, and support spacing.
Calculate lightning rod placement, protection radius, and down conductors.
Generate professional quotes with material, labor, markup, and tax, with GBQ (Glodon) bill-of-quantity export.
Design terminal block schedules and wiring diagrams.
Track all devices, equipment, and assets in your projects.
Voltage-drop and ampacity check with interpolation lookup; recommends the minimum section meeting both ampacity and drop limits.
Recommend a transformer from the standard capacity table; size reactive compensation Qc = P(tanφ1 − tanφ2).
Bill of materials linked to inventory — low-stock items are flagged automatically.
