FAQ
Where should beginners start?
For beginners, start with Tutorials, then the “Electrical Basics” path; after that, move to wiring and safety.
Are these tutorials safe for DIY?
Yes, but always follow safety notes; if unsure, consult a licensed professional.
What tools do I need?
Typically, a non-contact tester, a multimeter, insulated screwdrivers and proper PPE are enough.
What’s the difference between Articles and Tutorials?
In short, Tutorials are step-by-step lessons, whereas Articles are quick reads for specific topics.
Can I use these guides for my home wiring?
However, codes differ by region; therefore, always follow your local electrical code.
