Req 4c — Installing a Light Switch

A single-pole switch is one of the simplest wall devices in a house, but the repair still demands exact shutdown and careful reconnection. The reward is learning how a very common home control works from the inside.

What to Focus On

This requirement is about more than swapping old for new. It is about understanding the process:

• Turn off the correct breaker
• Verify power is off
• Remove the switch carefully
• Observe how the wires were connected
• Install the replacement device securely
• Restore the cover and test the result safely

This project is a good test of neatness. Wires should not be forced into a messy tangle, and the finished device should sit straight in the box.
