Electrical Design Engineering: Loads, Cables, Breakers and Distribution
How a building or plant electrical system is designed on paper before anyone buys a cable: AC and DC fundamentals, star and delta, power factor, connected and demand load, diversity and demand factors, load estimation in Excel, reading drawings, power factor correction, panel boards and single-line diagrams, fuses and circuit breakers with trip curves, AF and AT and breaking capacity, cable construction, derating, sizing and voltage drop, conduits, UPS, transfer switches and lightning protection.

What you will learn
Estimate loads with demand and diversity factors, build a load schedule, correct power factor with capacitor banks, draw a panel single-line diagram, select fuses and breakers by frame, trip and breaking capacity, choose cable construction and size cables by current, derating and voltage drop, size conduits, and specify UPS, automatic transfer switches and lightning protection.

Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.
- Questions answered in the context of the module you are on
- The same engineers who teach the AEP programme
- Career tools, CV help and public job listings included
- Your progress and notes stay in your account for good

Common questions
Which standards are used?
IEC by default, with NEC and IEEE factors where the lectures reference them; the method is the same under Indian practice.
Is this the same as the panel-building course?
No. This is the design that comes before the panel: loads, protection and cables. The panel course builds what this course specifies.
Do I need ETAP or AutoCAD?
No. A spreadsheet is enough; the ETAP and AutoCAD Electrical courses follow on from here.
Is the course really free?
Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.
What certificate do I get, and is it a vendor qualification?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not a vendor credential and is never described as one.
