Panel Board and Circuit Breakers

What is the purpose of a circuit breaker in a panel board?

• To regulate the flow of electricity in the circuit

• To protect the electrical circuit from overcurrent or short circuit damage.

• To increase the voltage in the circuit

• To prevent the circuit from overheating

Which type of circuit breaker is commonly used in residential buildings?

• Micro Circuit Breaker (μCB)

• Maxi Circuit Breaker (MXB)

• Giant Circuit Breaker (GCB)

• Miniature Circuit Breaker (MCB)

What is the function of a panel board in an electrical system?

• The function of a panel board is to provide internet connectivity to the building.

• The function of a panel board is to distribute electrical power to different circuits within a building or facility.

• The function of a panel board is to control the temperature of the electrical system.

• The function of a panel board is to regulate the water supply in the building.

What is the difference between a fuse and a circuit breaker?

• The difference between a fuse and a circuit breaker is that a fuse needs to be replaced after it breaks the circuit, while a circuit breaker can be reset and used again.

• A fuse and a circuit breaker both have the same size and shape

• A fuse and a circuit breaker both need to be replaced after breaking the circuit

• A fuse and a circuit breaker both can be reset and used again

Why is it important to have circuit breakers in a panel board?

• To increase energy efficiency

• To protect the electrical system from overloads and short circuits.

• To improve the appearance of the panel board

• To reduce the cost of electrical maintenance

What are the different types of panel boards available in the market?

• Circuit boards, fuse boards, and junction boxes

• Distribution boards, switchboards, and control panels

How does a circuit breaker protect the electrical system?

• It automatically cuts off the flow of electricity when it detects an overload or short circuit.

• It increases the flow of electricity to prevent overload

• It shuts off randomly without any reason

• It has no impact on the electrical system

What are the safety precautions to be taken while working with panel boards and circuit breakers?

• Ignore manufacturer's instructions

• Use any tools without insulation

• Wear appropriate PPE, ensure power is turned off, use insulated tools, follow lockout/tagout procedures, and follow manufacturer's instructions.

• Work with panel boards and circuit breakers alone

What is the role of a panel board in distributing electricity within a building?

• The role of a panel board is to regulate the water supply within a building.

• The role of a panel board is to provide internet connectivity within a building.

• The role of a panel board is to distribute electricity to different circuits and outlets within a building.

• The role of a panel board is to control the temperature within a building.

What are the signs of a faulty circuit breaker?

• Sparks flying from the circuit breaker

• Loud buzzing noise coming from the circuit breaker

• Circuit breaker feeling warm to the touch

• Frequent tripping, burning smell, visible damage, and lack of power to certain outlets or appliances
