When working on an electrical panel, it is important to follow these safety precautions:

1. Always turn off the power supply to the panel before starting any work.
2. Use insulated tools and wear appropriate personal protective equipment, such as gloves and safety goggles.
3. Avoid working in wet or damp conditions to prevent electrical shock.
4. Do not touch any exposed wires or components with bare hands.
