Msp Metallics Interview Questions, Process, and Tips

Voltage is the difference in electric potential between two points.

• Voltage is measured in volts (V).

• It represents the potential energy per unit charge.

• Voltage is necessary for current to flow in a circuit.

• Examples: 120V in household outlets, 12V in car batteries.

There are mainly three types of wiring: Cleat wiring, Casing and Capping wiring, and Conduit wiring.

• Cleat wiring involves the use of porcelain cleats to support the cables on walls or ceilings.

• Casing and Capping wiring uses PVC cables enclosed in wooden casings and capped with wooden covers.

• Conduit wiring involves the use of metal or PVC conduits to protect the cables and provide a neat finish.

There are two main types of motors: AC motors and DC motors.

• AC motors: Induction motors, synchronous motors

• DC motors: Brushed DC motors, brushless DC motors

• Examples: Induction motor, synchronous motor, brushed DC motor, brushless DC motor

There are several types of conveyor belts used in various industries for different purposes.

• Flat belt conveyors

• Modular belt conveyors

• Cleated belt conveyors

• Roller bed belt conveyors

• Wire mesh belt conveyors

ACB stands for Air Circuit Breaker, used for electrical protection. Cable size depends on current rating and voltage drop.

• ACB is a type of circuit breaker used for electrical protection in low voltage systems

• Cable size is determined by the current rating of the circuit and the allowable voltage drop

• For example, a 100A circuit may require a 10mm cable to ensure proper current carrying capacity

kW is real power, kvar is reactive power, kVA is apparent power.

• kW (kilowatt) is the actual power consumed by a device or system.

• kvar (kilovolt-ampere reactive) is the reactive power required by inductive or capacitive loads.

• kVA (kilovolt-ampere) is the total power in an AC circuit, combining both real and reactive power.

• The relationship between kW, kvar, and kVA can be represented by the power triangle.

• For example, in...read more
