The most common (and dangerous) mistake

When a multi-strand cable is connected directly under a screw designed for solid cable, this happens:

• The filaments are flattened irregularly.
• Some threads remain loose
• The pressure from the screw is not distributed evenly
• Electrical resistance appears
• The connection starts to heat up

That invisible heat is what, over time, ends up as:

• Intermittent outages
• Melted plastics
• Inner sparks
• Smell of burning
• Actual risk of fire

The image makes it clear: that type of tightening is NOT correct, even if it “works”.

So… how should it be done correctly?

Here comes the interesting part 👀The method shown by iBOYcrafts solves this problem cleanly and professionally.

The key is to convert the multi-strand cable into a solid and stable point of contact, instead of directly crushing it.

The safest solutions include:

• Splint-type terminals
• Adapters designed for screw terminals
• Fastening techniques that prevent the threads from opening

This not only improves electrical contact, but also:

• Reduces heating
• Increases the lifespan of the connection
• Complies with electrical best practices
• It makes the system safer

The curious thing is that almost nobody teaches it.

This type of detail is not explained in most quick tutorials, and many electricians learned it late… after seeing repeated failures.

That’s why these videos go viral: They don’t show something spectacular, they show what really matters.

That small change in the way a cable is connected can be the difference between:

• A reliable installation for years
• Or a hidden problem growing silently

Why does this issue matter today more than ever?

Today we use:

• More appliances
• More chargers
• Increased continuous electricity consumption
• Old installations with new cables

That makes the connections the weakest point of the system.

And that’s where this knowledge makes the difference.

Conclusion

It’s not about having expensive tools or being a professional electrician. It’s about understanding how real electrical contact works, not the “apparent” kind.

If you’ve ever connected a multi-core cable directly under a screw, this content just saved you:

• Faults
• Repairs
• And unnecessary risks

And that’s already a lot.
