What is the purpose of color-coding wires in electrical installations?

• To confuse electricians and create challenges

• To add a decorative element to the installation

• To easily identify the function of each wire and ensure proper connections, troubleshooting, and maintenance.

• To match the wires with the room's color scheme

What safety measures should be taken when working with electrical wires?

• Wearing metal jewelry for better conductivity

• Using wet hands to handle wires

• Ignoring safety gear and precautions

• Safety measures when working with electrical wires include wearing insulated gloves, ensuring power is off, using tools with insulated handles, avoiding water, and following wiring diagrams.

How can incorrect wire color coding lead to dangerous situations?

• By connecting wires incorrectly, such as reversing polarity or mismatching voltage, it can lead to dangerous situations.

• By improving wire insulation, increasing the risk of electric shock

• By reducing wire resistance, causing short circuits

• By enhancing wire conductivity, leading to overheating

What are the consequences of not adhering to wire color codes in electrical systems?

• Enhanced safety measures

• Improved efficiency in electrical systems

• Reduced risk of short circuits

• Consequences include confusion, incorrect connections, safety hazards, and potential damage to equipment.

What is the significance of using wire color codes in electrical systems?

• To make the wiring look more organized

• To easily identify different wires, functions, and ensure correct connections

• To confuse electricians and create challenges

• To match the wires with the room's color scheme
