Common Misconceptions

⚠️ Common Misconceptions

Misconception 1: "The neutral wire is safe to touch"

The neutral wire is at approximately 0 V and generally carries less risk than the live wire, but it is still part of the circuit and can be dangerous. In a faulty installation, it can carry voltage. Always treat all wires as potentially live and dangerous — never touch a bare wire without isolating the circuit first.

Misconception 2: "The earth wire protects by stopping current from flowing"

The earth wire protects by doing the opposite — it provides a very low resistance path for current to flow when there's a fault. This causes a very large current to flow, which blows the fuse or trips the circuit breaker, cutting off the power. Without this large current surge, the fuse would not blow and the fault would persist.

Misconception 3: "A higher fuse rating is always safer"

Using a fuse with a rating that's too high is actually more dangerous. The fuse will not blow even when dangerously high currents flow — meaning the wiring could overheat and cause a fire before the protection activates. The fuse must be rated just above the normal operating current, not far above it.
