How to Test Electrical Wires Yourself Without Proper Equipment

Testing electrical wires in your home can seem daunting without the right equipment. However, there are a few simple things you can do to check for basic functionality and safety without specialized tools. Here is how I test electrical wires myself when I don't have access to professional-grade equipment.

Understanding Electrical Wiring Basics

Before testing wires, it's important to understand some basics about home electrical systems.

Testing for Continuity

One of the most basic tests is to check for continuity - that the electrical current can flow uninterrupted through a wire from end to end.
