Video Description

This video is a complete walkthrough of residential and commercial electrical panels. If you're new to the trade or looking to brush up on your knowledge, this covers everything you need to know to understand, install, and troubleshoot panels correctly. Inside this episode: ✅ Panel vs. Load Center - what’s the difference? ✅ Busbars, bonding screws, neutral vs ground explained ✅ Main Breaker vs. MLO - and when you can convert ✅ What really determines panel amp rating (it’s not the breaker!) ✅ GFCI, AFCI, and Dual Function: which to use and why ✅ Pro tips for clean layout, wire protection & future-proofing ✅ And yes... we address that TikTok myth about breaker current 🔥 Thanks to @abb for sponsoring this one and supporting the next generation of tradespeople. ABB’s ReliaHome P-Series+ load centers gives you the same quality and layout GE users have relied on for years, now under a name that's pushing innovation in the field. This plug-on neutral system is fast to install, reliable under load, and even includes replacements for legacy GE breakers.
