Why an Electrical Diagram Quiz Helps

Diagrams look like code until you know the symbols. A quiz is a quick way to find the gaps. For example, many people mix up a dot, which means connected, with two lines that simply cross.

Also, the same part has different names across countries. The US says three-way switch and GFCI. The UK and Australia say two-way switch and RCD. The quiz uses both, so you learn to read diagrams from anywhere.

Safety: this quiz and the guide are for reading diagrams only. They do not teach installation. Never open a panel, switch plate or wall box yourself. Call a licensed electrician.

What to Do After the Quiz

If you missed a few questions, that is normal. First, open the free guide and find the diagram that matches the question. Then trace it with your finger from the source to the load and back. Finally, retake the quiz in a day or two.
