Aparna Constructions and Estates Interview Questions and Answers

MCBs protect lighting circuits from overloads and short circuits, ensuring safety and reliability in electrical systems.

• MCB stands for Miniature Circuit Breaker, used to protect electrical circuits.

• In lighting applications, MCBs prevent overloads that can cause fires.

• Example: A 10A MCB is suitable for residential lighting circuits.

• MCBs can be single or multi-pole, depending on the circuit requirements.

• They provide...read more

The full load current for a 1.5 sq mm wire depends on its insulation type and installation conditions.

• 1.5 sq mm copper wire typically carries around 10-15 amps under normal conditions.

• For PVC insulated wires, the current rating is usually lower than for XLPE insulated wires.

• In a conduit, the current rating may be higher due to better heat dissipation.

• Example: A 1.5 sq mm wire in a domestic circuit may handle 16 am...read more

I approach problems systematically, analyzing the situation, brainstorming solutions, and implementing the best course of action.

• Identify the problem clearly: For example, if a project is behind schedule, determine the root cause, such as resource allocation issues.

• Gather relevant data: Collect information from team members, project timelines, and budgets to understand the scope of the problem.

• Brainstorm potential...read more

The weight of 1 meter length depends on the material being measured.

• The weight of 1 meter length can vary depending on the material, such as steel, aluminum, wood, etc.

• To calculate the weight, you need to know the density of the material.

• For example, the weight of 1 meter length of steel would be different from 1 meter length of wood.

The store process refers to the set of procedures and protocols followed in the store for efficient operations.

ELCB stands for Earth Leakage Circuit Breaker. It is a safety device that automatically switches off the electrical circuit when it detects a current leakage.

• ELCB is used to protect against electric shock and fire hazards caused by faulty wiring or appliances.

• It works by detecting the difference in current between the live and neutral wires.

• If the current leakage exceeds a certain level, the ELCB trips and cuts of...read more
