The 5 golden rules of electrical safety and practice are fundamental principles that help ensure the safe and efficient operation of electrical systems. Here they are:

### 1. **Turn Off Power Before Working**
   - Always ensure that the power supply is turned off before starting any work on electrical circuits or equipment. This reduces the risk of electric shocks or accidents.

### 2. **Use Proper Insulation**
   - Ensure that all electrical wires, tools, and equipment are properly insulated to prevent accidental contact with live parts. Insulation helps to protect against electrical shocks.

### 3. **Use the Right Tools**
   - Always use the appropriate tools for electrical work. Insulated tools, such as screwdrivers, pliers, and wire cutters, are designed to reduce the risk of electric shocks.

### 4. **Follow Correct Wiring Procedures**
   - Properly follow wiring standards and procedures to prevent short circuits or wiring mistakes. Incorrect wiring can cause equipment malfunction, damage, or even fires.

### 5. **Check and Test Everything**
   - Before finalizing any electrical setup, always check and test all connections, circuits, and equipment to make sure they are functioning properly and safely. This ensures no potential hazards are left behind.

By following these rules, you ensure both your safety and the reliability of electrical systems!
