How to measure voltage when wiring a distribution box

Home / How to measure voltage when wiring a distribution box

Use a volt meter to measure voltage at the power supply and at the power distribution box. Long cable runs can result in a voltage drop, which can be solved by using a heavy gauge wire. The electrical breaker box, also known as a distribution panel or load center, is the heart of your home's electrical system. Here we demonstrate how to use both an older analog VOM (Volt-Ohm Meter) and how to use use a DMM (Digital Multi-Meter) to measure voltage levels in building electrical wiring and electrical service.
