Internet Comments

I recently posted a TikTok that I honestly didn’t think would turn into anything crazy.

It was just a simple calculation challenge:
Can a 20A breaker handle a 120V load adding up to 1800W?

Do the math:

1800 ÷ 120 = 15 amps

Simple. Straightforward. Most people looked at that and said:

“Yeah, you’re good.”

And on the surface—they’re not wrong.

But like always… the comments turned into something way bigger.

🔌 The Divide in the Comments

Almost immediately, the comment section split into two groups:

• People who actually understood what I was getting at

• People who either disagreed or didn’t fully hear the point

And I’m starting to notice this more and more in the trade:

Everyone has an opinion… but not everyone explains it.

Some guys came in solid:

• Dropping code references

• Explaining the 125% rule

• Actually adding value to the conversation

That’s the side of TikTok I respect.

But then you’ve got the other side…

⚠️ “You’re Wrong” Isn’t an Argument

A lot of the pushback was just:

• “Wrong.”

• “That’s not how it works.”

• “You shouldn’t be teaching this.”

No breakdown. No reasoning. No code.

And that’s where I think the disconnect is in this trade sometimes.

A lot of people go off what they were told—
not what they actually understand.

🧠 What I Was Actually Showing

The video wasn’t about:

“Can 15 amps run on a 20 amp breaker?”

That’s obvious.

What I was really getting at was:

What happens when that load becomes continuous?

That’s the part people skip.

Because now it’s not just:

Watts ÷ Volts = Amps

Now it’s:

How long is that load running?

If that heater runs for 3+ hours, now we’re in continuous load territory.

Which means:

• You size it at 125%

• Or think of it as 80% usable on the breaker

So now that same 15A load is no longer just “fine”—
it’s right up near the limit.

🧠 What I Took Away From It

I don’t mind being wrong. At all.

That’s how you actually get better in this trade.

Electricity doesn’t care about opinions.
It follows physics, and it follows code.

So when someone comes in with:

• Logic

• Real experience

• Code references

I’ll listen every time.

But the noise? The ego?

That doesn’t teach anything.

🔍 Why I’m Still Posting

I’m still going to post these challenges.

Not because I think I’m always right—but because:

• It starts real conversations

• It makes people think deeper than surface-level math

• It forces me to double-check myself

And honestly?

Sometimes the comment section turns into the best classroom.

⚡ Final Thought

If you’re in the electrical trade, you already know:

There’s always more to learn.

So instead of shutting people down, we should be:

• Explaining things

• Backing it up with code

• Actually helping people understand why

Because at the end of the day—

Knowing why something works
is way more powerful than just saying
“that’s how it’s done.”
