I don’t recommend that you do any do-it-yourself house wiring projects without some instructions. For any wiring projects in your house electrical wire diagrams would be a necessity in my opinion.
The reason is that the diagrams are color coded to show you which wires are ground, which are neutral and which are “hot.” The hot or the live wires are the wires that deliver the power and which could potentially harm you if you are not careful.
In addition to the color coding you’ll find symbols on these diagrams which will help you identify the types of switches and so forth. Become familiar with your diagram and you’ll have an easier time doing the wiring in your house; or if you’re still unsure of yourself-just call an electrician.
