Answer 1

We should never turn the switch in ON position.

Explanation:

Precautions that need to be taken:

1. Never touch a lighted electric bulb connected to the mains: This is dangerous as the bulb and its connections may be live, leading to an electric shock.

2. Never experiment with the electric supply from the mains, generator or inverter: Doing so can cause electric shocks, short circuits or even fire hazards.

3. Never use just any wire or strip of metal in place of a fuse: A fuse is designed to protect the circuit from overloads. Using improper materials can lead to fire hazards or damage to electrical components.
