- Q1. Electrical mentenanc work experience
- Q2. ElCB full form and MCB full form
- Ans.
ELCB stands for Earth Leakage Circuit Breaker and MCB stands for Miniature Circuit Breaker.
ELCB is a safety device used to protect against electrical shock caused by earth faults.
MCB is a type of circuit breaker that automatically switches off electrical circuits during abnormal conditions.
ELCB detects current leakage to earth and disconnects the circuit, while MCB protects against overloads and short circuits.
- Q3. Earth leakeg circuit breaker and menutur current breaker
- Q4. ElCB sefty protection
- Q5. MCB over load protection
- Ans.
MCB (Miniature Circuit Breaker) provides overload protection by automatically switching off the circuit when current exceeds the rated capacity.
MCB trips when current exceeds its rated capacity to prevent overheating and potential fire hazards.
Overload protection is essential to protect electrical appliances and wiring from damage.
Examples of MCB overload protection include tripping when too many devices are connected ...

- Q1. Difference between single phase and three phase?
- Ans.
Single phase and three phase are two types of electrical power distribution systems.
Single phase has one live conductor and one neutral conductor, while three phase has three live conductors and one neutral conductor.
Single phase is commonly used in residential and small commercial applications, while three phase is used in industrial and large commercial applications.
Single phase power supply is suitable for low power...
- Q2. What is the difference between R phase, Y phase, B phase?
- Ans.
R, Y, B phases are the three phases of AC power supply. They differ in their phase angle and voltage level.
R phase has a phase angle of 0 degrees and is usually connected to the red wire.
Y phase has a phase angle of 120 degrees and is usually connected to the yellow wire.
B phase has a phase angle of 240 degrees and is usually connected to the blue wire.
The voltage level of each phase is the same, but they are out of ph...
- Q3. Voltage and current difference between Series and parallel of two or more batteries?
- Ans.
In series, voltage adds up while current remains the same. In parallel, voltage remains the same while current adds up.
In series, batteries are connected end-to-end, positive to negative. In parallel, batteries are connected positive to positive and negative to negative.
Series connection increases voltage but does not increase current. Parallel connection increases current but does not increase voltage.

Ensure that the battery is securely fastened in place
Check the electrolyte level and top up with distilled water if required
Test the battery voltage and recharge if necessary
- Q5. How to find in a faulty battery?
- Ans.
A faulty battery can be identified by checking its voltage, capacity, and physical appearance.
Check the voltage of the battery using a multimeter
Test the capacity of the battery using a battery tester
Inspect the physical appearance of the battery for any signs of damage or leakage
Check the battery terminals for corrosion or loose connections
Compare the battery's performance to its specifications
- Q6. What is the difference FUSE, MCB, ELCB, RCCB?
- Ans.
FUSE, MCB, ELCB, and RCCB are all electrical protection devices, but they differ in their functions and applications.
FUSE is a simple device that protects electrical circuits from overloading or short-circuiting by melting and breaking the circuit.
MCB (Miniature Circuit Breaker) is an automatic switch that trips and cuts off the power supply when there is an overload or short-circuit.
ELCB (Earth Leakage Circuit Breaker...
- Q7. Draw the diagram of DOL starter.
- Ans.
