Abdul Wassay | Electrical Engineer & Founder, Azad Circuit Hub
Last updated: 21-07-2026
Abdul Wassay is an electrical engineer with over 15 years of hands-on experience across industrial electrical systems, EPC (Engineering, Procurement, and Construction) projects, and renewable energy installations.
He is the founder and lead author of Azad Circuit Hub, where he publishes practical, standards-based engineering guides and free calculators used by working engineers, electricians, and students worldwide.
His background spans PLC and SCADA programming, industrial automation, electrical troubleshooting, and power system protection — experience drawn directly from site work on live panels, switchgear, and control systems rather than from theory alone.
That field background is why Azad Circuit Hub’s content leans on worked examples, code citations (NEC, IEC, IEEE), and calculators that mirror what an engineer actually has to compute on a real project, not textbook simplifications.
Professional Background
Over 15 years in the electrical industry, Abdul has worked on:
- EPC project execution — Industrial plant electrification, substation commissioning, MV/LV distribution design & Renewable projects execution
- Industrial automation — PLC and SCADA system design, programming, and commissioning for manufacturing, oil & gas, utilities
- Protection & control — relay coordination, overcurrent/earth fault/differential protection settings, and switchgear protection schemes
- Renewable energy systems — solar PV design and integration
- Electrical troubleshooting & maintenance — insulation resistance testing, transformer testing, motor diagnostics, and field commissioning
Education:
B.Sc. in Electrical Engineering
Areas of Expertise:
Abdul writes and reviews content across the following technical clusters on Azad Circuit Hub:
- Busbar Sizing, Ampacity & Protection — IEC/NEC compliant sizing, current carrying capacity, thermal withstand, and clearance calculations for panel and switchgear design.
- Relay Protection & Coordination — overload, earth fault, differential, and overcurrent relay settings per IEC 60255 and IEEE C37.112.
- Cable Tray, Conduit & Fill Calculations — NEC 392-cited sizing for tray, conduit, and pull box installations.
- Transformers & Power Systems — transformer testing, cooling methods, protection schemes, and manufacturer comparisons.
- Motors, Drives & Industrial Control — motor testing, VFD applications, and industrial automation.
- Solar & Renewable Energy Systems — solar PV sizing and renewable integration.
- Electric Vehicle Charging & E-Mobility — EV charger sizing and infrastructure.
- US Electricity Bill Calculators by Utility — utility-specific rate structures and bill estimators.
- Electrical Testing & Maintenance — insulation resistance testing, transformer testing, and field diagnostics.
- Electrical Calculators Library — the full collection of tools Abdul has built and maintains.
Editorial & Publishing Approach
Every calculator and guide on Azad Circuit Hub is built to a consistent standard: cited against NEC, IEC, or IEEE code where applicable, checked against real-world field values rather than idealized textbook numbers, and written to be usable by a working engineer under time pressure — not just a student studying for an exam.
Where standards differ by region (IEC vs. NEC vs. BS 7671), that’s stated explicitly rather than assumed. Content is reviewed and updated as codes and standards change.
