Unlocking the Basics: Inside a Main Panel

Описание: The main electrical panel is the heart of every electrical system. In this video, licensed Master Electrician Dustyn from Smarter Sparky walks you step-by-step through the major components inside a residential main breaker panel and explains how 120V and 240V power is distributed throughout your home.

If you’ve ever wondered:
• How does power get from the utility transformer into my panel?
• What does the main breaker actually shut off?
• How do hot bus bars create 120V and 240V circuits?
• Why can neutral and ground land on the same bar in the main panel?
• What does the main bonding jumper actually do?
• What is a supply-side bonding jumper?
• Do ground rods trip breakers?

This video answers all of it in a clear, practical way.

You’ll learn about:
• Service entrance conductors (service drop vs service lateral)
• The 2020 NEC emergency disconnect requirement
• Split-phase power explained simply
• Main breaker safety and energized lugs
• Alternating bus bar layout inside a panel
• Single-pole vs two-pole breakers
• Why you cannot use two single-pole breakers for 240V
• Neutral vs ground explained clearly
• The main bonding jumper (green screw)
• The grounding electrode system and lightning protection

This is a panel-level overview designed to make the electrical panel feel logical instead of mysterious. Future videos will dive deeper into split-phase theory, grounding and bonding, and specific branch circuit installations.
