Ambience Mall Maintenance Electrician Interview Questions and Answers

There are several types of circuit breakers used in electrical systems.

• Thermal circuit breakers: use a bimetallic strip to detect and respond to excessive heat

• Magnetic circuit breakers: use a solenoid to detect and respond to high currents

• Ground fault circuit interrupters (GFCIs): detect imbalances in electrical currents to prevent electric shocks

• Arc fault circuit interrupters (AFCIs): detect dangerous electrical arcs ...read more

Miniature Circuit Breakers (MCBs) are types of circuit breakers used in electrical systems to protect against overcurrents.

• MCBs are commonly used in residential, commercial, and industrial applications.

• They are available in different current ratings, such as 6A, 10A, 16A, 20A, etc.

• MCBs can be single-pole, double-pole, or triple-pole, depending on the number of phases they can handle.

• Some common types of MCBs include B-...read more

A diesel generator works by converting diesel fuel into mechanical energy, which is then converted into electrical energy.

• Diesel fuel is injected into the combustion chamber of the generator.

• The fuel is ignited by the heat of compression, causing it to combust and expand.

• The expansion of the combusted fuel pushes the piston, creating mechanical energy.

• The mechanical energy is then converted into electrical energy throu...read more

A circuit breaker is a device that automatically interrupts the flow of electric current in a circuit to protect against overcurrent or short circuit.

• Circuit breakers are designed to prevent damage to electrical equipment and reduce the risk of electrical fires.

• They work by detecting excessive current flow and quickly opening the circuit to stop the flow of electricity.

• Common types of circuit breakers include thermal, ...read more

AC supply is alternating current that changes direction periodically, while DC supply is direct current that flows in one direction constantly.

• AC supply changes direction periodically, while DC supply flows in one direction constantly

• AC supply is commonly used in household appliances, while DC supply is used in electronics like computers and phones

• AC supply is generated by power plants and transmitted over long distanc
