Maruti Suzuki Mechanical Foreman Interview Questions and Answers

A circuit breaker is an electrical switch that automatically interrupts the flow of current when it exceeds a certain limit.

• It is used to protect electrical circuits from damage caused by overloading or short circuits.

• It works by detecting the excess current and tripping the switch to break the circuit.

• It can be reset manually or automatically depending on the type of circuit breaker.

• Examples include thermal circuit br...read more

A contactor is an electrical switch used for switching an electrical circuit on or off.

• It is used to control electric motors, lighting, heating, and other electrical loads.

• It consists of a coil, contacts, and an enclosure.

• The coil generates a magnetic field that pulls the contacts together to close the circuit.

• Examples include HVAC systems, elevators, and industrial machinery.

• Contactor ratings are based on the amount o...read more

MCB stands for Miniature Circuit Breaker. It is an electrical switch that automatically shuts off the electrical circuit during an overload or short circuit.

• MCB is a type of circuit breaker that is commonly used in residential and commercial buildings.

• It is designed to protect electrical circuits from damage caused by overloading or short circuits.

• MCBs are available in different current ratings and can be easily replac...read more

A motor is a device that converts electrical energy into mechanical energy to produce motion.

• Motors are used in various applications such as electric vehicles, industrial machinery, and household appliances.

• There are different types of motors such as DC motors, AC motors, stepper motors, and servo motors.

• The basic principle of a motor is the interaction between a magnetic field and an electric current.

• Examples of motor...read more

A current transformer is a device that measures the current flowing in a circuit by producing a proportional current in its secondary winding.

• Consists of a primary winding and a secondary winding

• Primary winding is connected in series with the circuit carrying the current to be measured

• Secondary winding is connected to a measuring instrument or protective relay

• Produces a current in the secondary winding that is proporti...read more

The engine works by converting fuel into energy through combustion, which powers the pistons and turns the crankshaft.

• Fuel is mixed with air and ignited in the combustion chamber

• The resulting explosion pushes the piston down, which turns the crankshaft

• The crankshaft converts the linear motion of the piston into rotational motion

• The rotational motion is transferred to the wheels through the transmission

• Examples of engin

TSB stands for Technical Service Bulletin.

• TSB is a document issued by a manufacturer to provide information and instructions regarding a specific technical issue or problem.

• It is typically distributed to technicians and service centers to help them diagnose and repair the issue.

• TSBs often include step-by-step instructions, diagrams, and recommended solutions.

• They can cover a wide range of topics, such as software updat...read more

BS4 and BS6 are emission norms for vehicles, with BS6 being more stringent and environmentally friendly.

• BS4 stands for Bharat Stage 4 and BS6 stands for Bharat Stage 6.

• BS4 emission norms were implemented in India in 2017, while BS6 norms were implemented in 2020.

• BS6 vehicles emit lower levels of harmful pollutants like nitrogen oxides and particulate matter compared to BS4 vehicles.

• BS6 compliant vehicles require the us...read more
