This Week in Numbers & Progress

Study time: 3–4 hours every day
Module 5: 15 of 25 classes complete (two classes per week, ~3 hours each)
Question volume: averaging ~300 questions per week across practice sets, QOTW posts, and material being written for the Brain Buster packets
Focus remains on the small details — minute 2026 wording changes, calculation edge cases, and forcing theory to connect directly to the math while also looking ahead at structural prep for the 2029 cycle.

Thanks for reading! This post is public so feel free to share it.

Journal Entry This Week: “Why.”

Thursday’s entry is live. Title is simply “Why.”

I wrote about being a kid using pipe cleaners and cardboard boxes like they were wires, about twisting copper in the field, and about the real reason I refuse to treat this trade as just a paycheck. I want to understand the physics, the math, and the science behind every rule. I want to own the company that does the work and build an education system that actually teaches apprentices why they should care instead of gatekeeping them.

The only teacher who ever gave me the exact push I needed was Paul Abernathy — a short email years ago that said I got a question right and that I should defend my stance. That single message still fuels everything. Full entry is on Substack.

Upcoming journal entries already planned:

Why Workmanship Still Matters

1. When Mushrooms Start Acting Electrical
📅 October 21, 2026

I’ve been thinking about something weird lately. We normally treat electricity as something humans invented — wires, circuits, motors, grids. But electricity itself is a natural part of biology.

Blue oyster mushrooms (and their mycelium networks) generate and propagate electrical signals. Researchers have recorded spikes and patterns that look a lot like information transmission. It’s not a mushroom language (yet), and it’s not radio waves being broadcast through the air. It’s closer to a living biological electrical network.

Plants do it too. Cells maintain electrical gradients. Our own nervous systems run on the same fundamental principle. The technology we install every day is basically us learning how to control forces that already exist in nature.

Next time you see a blue oyster mushroom on a log, you’re looking at a living network capable of generating electrical activity. That’s pretty damn cool. Keep questioning how the world works.

2. Mentally Preparing for the 2029 NEC Cycle
📅 October 18, 2026
Read it here

The 2029 NEC is still years away, but the Code is already giving us a preview. Informative Annex L shows a proposed organizational structure for the next cycle. It’s not enforceable, but it’s valuable.

Every new edition creates an adjustment period — the information is still there, but it moves. Articles get reorganized. References change. Instead of waiting until the book drops and trying to relearn everything at once, start getting comfortable with the direction the organization is heading.

This isn’t about memorizing future code. It’s about developing the mindset: “Where is this information going?” Being good at the NEC isn’t just memorizing sections. It’s being able to navigate change. 2029 might feel far away, but preparing your brain starts now.

Questions of the Week – Full Answers & Explainers

1. Box Fill (2026 NEC 314.16)
Metal outlet box with:

3 × #12 THHN terminating on a duplex receptacle
3 × #12 THHN passing through
1 duplex on a single yoke
Internal cable clamps
2 × #12 EGCs spliced together

Allowances at 2.25 in³ each: 6 conductors + 1 clamp + 2 device + 1 EGC set = 10 × 2.25 = 22.5 cu in.
Correct answer: (C) 22.5 cu in.

2. System Bonding Jumper – Separately Derived System
Two parallel 3/0 AWG Cu per phase into one enclosure = 335.6 kcmil total.
Table 250.102(C)(1) “Over 3/0 through 350 kcmil” → 2 AWG Cu.
Correct answer: (B) 2 AWG Copper.

Both were posted with full section citations so people can learn the method, not just copy the letter.

Brain Buster Packets – Current Work

Packet 3 is being written right now and will contain 50 questions.
Every Quick Hit chapter is planned to eventually receive its own 500+ question Brain Buster packet balanced across the articles in that chapter.
A large portion of the ~300 weekly questions I’m grinding are being created or refined specifically for these packets.

Deep NEC Web Browsing – Episode 8

Saturday’s episode (live on Substack): Exploring Chapter 3 – General Requirements for Wiring Methods and Materials (Article 300).

Covered:

Scope of Article 300 (≤ 1000 V AC / 1500 V DC)
NEMA GD-1 standards for water-damaged equipment
American Fittings manufacturer resources
Conductor grouping rules (300.5) and why parallel runs must stay together to prevent inductive heating
Quick Hits walkthrough of the site resources

Trade News & Knowledge Sources This Week

Master The NEC Podcast (Paul Abernathy) officially crossed 1,000,000 downloads. I left the congratulations comment immediately.
Electrical Contractor Magazine (Apprentice Edition + October issue): GFCI vs AFCI (Mike Holt), key 2026 changes to Articles 90–130 (Kyle Krueger), bonding locknuts & service terminology (Jim Dollard / Derek Vigstol), arc-flash hazard communication (Tom O’Connor), and Michael Johnston’s workmanship piece.
NECA Code Question of the Day series kept delivering real field scenarios (3R enclosure wet/damp classification, rooftop temperature adders, horticultural lighting SPGFCI issues, etc.).
Broader industry notes: transformers under heavy strain from AI/data-center demand, grid modernization funding moving, permitting reform still being pushed.

Three important Paul Abernathy videos watched/re-watched this week:

Recommended Listen – Shock Week with Thomas Domitrovich
Fault-Managed Power (Class 4): How it Works – The Technology Behind Safer DC Distribution
October 22, 2026 • ~30 min
Listen here

Excellent technical breakdown of Class 4 Fault-Managed Power systems: how the transmitter/receiver setup works, how the system detects faults and limits energy, UL 1400/1401, NEC terminology, line-to-line vs line-to-ground vs arc faults, and real-world applications (including the Sinclair Hotel project). Highly relevant as DC distribution and fault-managed power keep growing in the Code and in the field.

Community & Platform Status

Clapper completely discontinued its community features.
