From The Build Show.
On this Best of the Build Show episode, Build Expert Travis Brungardt breaks down the essentials of box fill calculations for electrical installations and why choosing the correct electrical box matters for your projects. Travis explains how to determine the proper box size based on volume and the number of conductors, grounding wires, and devices you’ll be installing. He covers basic math formulas, code references from the NEC and IRC, and common mistakes that can lead to safety risks or failed inspections. Whether you’re a professional electrician, a builder, or a DIY enthusiast, this video offers clear, practical guidance to keep your electrical installations safe and code compliant.
