The Story Behind Engineer Tsai

I did not start in an elite program. Instead, I learned on job sites.
Over time, I turned hard lessons into clear notes. As a result, I now teach electrical and MEP in a simple way.
In short, my goal is clarity, safety, and action.

What I believe

First, safety comes first. Second, diagrams and numbers beat jargon.
Finally, every lesson should end with a next step.

My Journey

At first, I traced wires and verified faults with a meter. Later, I noticed a gap: many guides were heavy on theory yet light on practice. Because of that, I began publishing short explainers and step-by-step tutorials. For instance, I cover panel labels, breaker choice, load math, and spec sheets. In addition, each idea maps to a safe action you can take tomorrow.

Over time, several outcomes stood out. First, study maps helped beginners pass entry-level tests without rote notes.
Next, long manuals became one-page checklists for panels and lighting.
Finally, power-and-cost calculators sped up decisions and, as a result, made them safer.

Above all, knowledge should never be a barrier to your dreams.

What You’ll Learn Here

Core concepts, made practical
First, we cover voltage, current, power factor, and protection. Then, we link each idea to a field action. Consequently, you know why each step matters.

DIY & troubleshooting
You will isolate safely, test continuity, and read fault symptoms. For example, we fix outlets, lighting, tripping breakers, and noisy loads.

MEP workflows
Meanwhile, we plan panel schedules, size conductors, and choose protection. Moreover, we read datasheets, compare standards, and prepare submittals.

Study maps & templates
Each guide ends with a printable checklist. In addition, you can download Excel tools.

Methods & Tools

In practice, my approach is simple: Signal → Diagnose → Act.
First, spot the signal. Next, verify it with a meter. Finally, apply the smallest safe fix.
Besides that, I keep an assumptions table and a one-page playbook.
Meanwhile, common tools include a multimeter, a clamp meter, an insulation tester, and basic loggers.

Who This Helps

Career changers, when you need a clear path.
Students, while you prepare for certifications.
Homeowners and makers, if you want safe DIY steps.
Technicians and pros, when you prefer checkable references.

Teaching Style

I write the way I learned. Specifically, I show numbers, prove each step, and end with action.
As a result, you gain skill and confidence—not just facts.
When needed, I add diagrams or a checklist so the step is easy to repeat.

Safety & Limits

Electrical work is risky. Thus, follow local codes and site rules.
If in doubt, ask a licensed professional.
Above all, isolate and test before touch.

FAQ

Q1: I’m a beginner. Where should I start?
Start with the Basic Lessons series. Each post ends with a checklist and a next step so you don’t get stuck.

Q2: Do you teach code compliance?
I explain concepts and typical practices, then point to standards. Always follow local codes and your site’s rules.

Q3: Can I use your checklists at work?
Yes—download and adapt them. Add your site’s acceptance criteria and keep a change log.

Q4: What tools do I really need at home?
A reliable multimeter, non-contact tester, insulated screwdriver set, and a notebook for readings. Add a clamp meter if you log current.

Q5: How do you keep content accurate?
I include assumptions and references, test steps in the field where possible, and revise checklists based on reader feedback.
