Josh The Sparky - Week 4 April 12

SPARKY WEEKLY

🗓️APRIL 12, 2026

Weekly Digest
This week was a solid push — especially on TikTok and confirming knowledge.

I’ve been dialing in more content and staying consistent with posts. The biggest thing I’m noticing is that the more I explain electrical code in quick hits, the more it forces me to tighten up my own understanding. Making short videos sounds simple, but if you’re going to explain NEC concepts quickly and clearly, you actually have to know the material pretty well.

One thing I’m working on is not getting distracted by TikTok comments that miss the point of the quick hits. A lot of the videos are meant to be quick concepts, not a full code seminar. But at the same time, those comments can still turn into learning opportunities. Sometimes they bring up a different angle, sometimes they show where clarification is needed, and sometimes they remind me that explaining code clearly is harder than it looks.

Instead of letting it derail the message, I’m trying to take the useful parts and use that feedback to make the next post better.

On the study side, I went through another questionnaire packet this week, and it reinforced something I’ve been noticing for a while:

A lot of these question packets just don’t hold up.

Some are outdated, some explanations are weak, and some answers don’t really walk you through the reasoning the way the NEC expects you to think. Passing an exam isn’t just about memorizing answers — it’s about understanding how to actually navigate the code.

Because of that, I’m leaning more heavily into Fast Trax practice questions going forward. The structure is better, and the questions force you to think through the code path instead of just guessing. That’s going to be a big part of my ultimate prep strategy.

I’ve also noticed my questions on the Fast Trax forums are starting to gain some momentum, which has been cool to see. The discussions there go deeper into why an answer is correct, which helps way more than just seeing the right letter on a multiple-choice test.

Code-wise, this week, I spent time really working through continuous vs noncontinuous loads and how they relate to Article 210 branch circuits. Knowing when that 125% continuous load rule applies versus when it doesn’t is one of those things that seems simple at first, but can definitely trip you up if you’re not paying attention.

Another thing that’s starting to click more is box fill calculations. The more problems I work through, the easier they’re getting. Once you understand conductor equivalents and what counts as what in the box, it starts turning into a system rather than guessing.

I’ve also been digging deeper into grounding vs bonding. I’m getting to the point where I understand the difference conceptually, but this is definitely one of those areas where the deeper you go, the more there is to learn. Understanding the purpose is one thing — really understanding the application throughout the code is another level.

On top of that, I’ve been keeping up with Thomas Domitrovich and some of the public inputs being discussed for the upcoming National Electrical Code 2029. It’s actually pretty interesting seeing how the code evolves before it ever gets printed. Watching that process helps you understand why certain rules exist in the first place.

At the same time, I’m also continuing to prepare for the Massachusetts Electrical Code Amendments 2026, since those changes will directly affect how we’re working here.

Another thing I came across this week was the National Electrical Contractors Association YouTube channel. They do daily question breakdowns that walk through code questions step by step. I’ve been finding those really interesting because it’s another way to see how experienced electricians approach the codebook.

Overall — solid week.

More studying.
More content.
More questions.
More understanding.

Everything is stacking.
