Most electricians think knowledge is what you can see on the surface — wiring devices, bending conduit, pulling wire, passing inspection.
But that’s only the tip of the iceberg.
The real understanding of electricity goes way deeper, and most of it is never taught clearly in the field or even in school.
This is what the Electrician’s Knowledge Iceberg is about.
The Electrician's 12-Layer Knowledge Iceberg is a roadmap of what it truly takes to master the electrical trade. While most people only see wiring devices, pulling cable, and installing equipment, that's just the tip of the iceberg.
Each layer explores a deeper level of electrical knowledge—from basic safety, tools, and NEC requirements to electrical theory, troubleshooting, grounding and bonding, power quality, transformer behavior, system design, fault analysis, and engineering-level concepts. As you descend through the iceberg, you'll discover that becoming a great electrician isn't just about memorizing the Code—it's about understanding why electrical systems behave the way they do.
Whether you're a brand-new apprentice, a seasoned journeyman, an inspector, or simply someone passionate about electricity, this series is designed to help you continuously expand your knowledge and challenge the way you think about the trade.
The deeper you go, the fewer people have been there—but that's where true mastery begins.
12 Layers.
One trade.
An almost endless amount to learn.
The Electrician's Knowledge Iceberg is a 12-layer roadmap through the knowledge required to truly understand the electrical trade.
Each layer takes you further beneath the surface.
From the fundamentals every electrician should know...
To advanced concepts that many electricians may never encounter during their careers.
You'll explore topics including:
These aren't simply twelve topics to memorize.
They're twelve layers of understanding.
The electrical trade is much deeper than what you encounter on a typical jobsite.
Behind every circuit, conductor, transformer, disconnect, breaker, and piece of equipment is an entire world of electrical theory, calculations, system behavior, troubleshooting, design, and engineering.
The things you can physically see and install are only the tip of the iceberg.
As you go deeper, the questions change.
Instead of asking:
"What does the Code say?"
You start asking:
"Why does the Code require it?"
Then:
"Why does the electrical system behave this way?"
And eventually:
"What happens when the system doesn't behave the way it was designed to?"
That's where true understanding begins.
The Electrician's Knowledge Iceberg is also being explored through a 12-part TikTok series, with each part diving deeper into electrical knowledge and the trade.
The series is designed to challenge the idea that electrical knowledge ends with:
"Because the Code says so."
There's always another layer.
VIDEO BREAKDOWN COMING SOON.
The knowledge you encounter every day on the job.
The fundamentals that begin connecting the pieces.
Where memorization begins giving way to understanding.
The systems and principles behind the equipment you're installing.
Understanding what happens when things don't work as expected.
Going deeper into how electrical systems interact and behave.
Moving beyond installation knowledge and into true system understanding.
Exploring deeper electrical behavior that isn't always visible from the jobsite.
Advanced concepts that aren't normally discussed during everyday electrical work.
Where electrical theory, calculations, system behavior, and design begin to intersect.
The territory of advanced practitioners, designers, engineers, and specialists.
The concepts that take you beyond simply installing electrical systems...
...and toward understanding why they work.
