Mcb stands for Miniature Circuit Breaker and MCCB stands for Molded Case Circuit Breaker.
Mcb is a type of circuit breaker that is used for low voltage applications.
MCCB is a type of circuit breaker that is used for high voltage applications.
Both Mcb and MCCB are used to protect electrical circuits from overloads and short circuits.
Mcb is usually rated for currents up to 100 amps, while MCCB can handle currents up to 25...
Current and voltage are two fundamental concepts in electricity. Current is the flow of electric charge, while voltage is the potential difference that drives the flow.
Current is the rate of flow of electric charge, measured in amperes (A).
Voltage is the force or pressure that pushes the electric charge to flow, measured in volts (V).
Current flows through a conductor, while voltage exists across a conductor.
Current is ...
A unit is a standard measurement used to quantify physical quantities. Current is measured in amperes (A) and voltage is measured in volts (V).
A unit is a fixed quantity used as a standard of measurement.
Current is the flow of electric charge in a circuit and is measured in amperes (A).
Voltage is the electric potential difference between two points in a circuit and is measured in volts (V).
The unit of current, ampere, ...
There are several types of transformers used in electrical systems.
Power Transformers
Distribution Transformers
Instrument Transformers
Auto Transformers
Isolation Transformers
Step-up and Step-down Transformers
Three-phase Transformers
Single-phase Transformers
D.OL starter is a type of motor starter used to start and stop three-phase motors.
D.OL stands for Direct-On-Line.
It is the simplest and most common type of motor starter.
It directly connects the motor to the power supply, providing full voltage to the motor.
It is suitable for small to medium-sized motors.
It does not provide any protection against overloading or short circuits.
It is commonly used in applications such as
An ampere (amp) is the unit of electric current in the International System of Units (SI).
Amperes measure the rate of flow of electric charge.
It is named after the French physicist André-Marie Ampère.
One ampere is defined as one coulomb of charge passing through a point in one second.
Amperes are used to measure the current flowing through electrical circuits.
Common household appliances like light bulbs and refrigerator...

There are various types of gearboxes used in maintenance fitting, including spur gearboxes, helical gearboxes, bevel gearboxes, and worm gearboxes.
Spur gearboxes have straight teeth and are commonly used in applications with low to moderate speeds and loads.
Helical gearboxes have angled teeth and provide smoother and quieter operation compared to spur gearboxes.
Bevel gearboxes are used to transmit power between shafts ...
Pitch is the distance between two adjacent threads in a screw or bolt.
Pitch is measured in millimeters or inches.
It determines the tightness of the screw or bolt.
Different types of pitch include coarse, fine, and extra fine.
Pitch is important in alignment as it affects the positioning of rotating machinery.
Misaligned pitch can cause vibration, noise, and premature wear and tear.
Misalignment is when two or more parts are not properly aligned. Backless refers to a type of shoe without a back.
Misalignment can cause wear and tear on machinery and decrease efficiency.
Examples of misalignment include a crooked belt on a conveyor or a misaligned shaft in a motor.
Backless shoes are typically sandals or slip-ons that do not have a heel or back portion.
Backless shoes can be more comfortable in hot weat
