- Active wire (brown), brings electricity in
- Neutral wire (blue), brings electricity out
- Earth wire (green, yellow), prevents electrocution
2
Q
What is a Fuse?
A
Wires of high resistance and low melting temperature, increased current melts the wire and breaks the circuit.
Must be manually replaced.
3
Q
What is a safety switch?
A
Detects leaking current in 0.03 seconds and breaks the circuit immediately. This protects you from electrocution.
