The current in a 3 phase system depends on the voltage and power of the system.
The current in a 3 phase system can be calculated using the formula: I = P / (sqrt(3) * V)
Where I is the current, P is the power, and V is the voltage
For example, if the power is 1000W and the voltage is 240V, the current would be approximately 4.33A
MCB stands for Miniature Circuit Breaker, a device designed to protect electrical circuits from overloads and short circuits.
MCB is a type of circuit breaker that automatically switches off electrical circuits during abnormal conditions like overload or short circuit.
It is commonly used in residential and commercial electrical installations to protect wiring and electrical equipment.
MCBs are available in different curr...
To check AC DC current, use a multimeter set to the appropriate setting and connect the probes to the circuit being tested.
Set the multimeter to the AC or DC current setting depending on what you are testing.
Ensure the multimeter probes are connected correctly to the circuit being tested.
Read the current measurement displayed on the multimeter.
For AC current, make sure the multimeter is set to the appropriate range (e....
To check cable continuity, use a multimeter to measure resistance between two points on the cable.
Use a multimeter set to the resistance or continuity mode.
Connect one probe to one end of the cable and the other probe to the other end.
A low resistance reading indicates good continuity, while a high resistance or infinite reading indicates a break in the cable.
Check for continuity in each conductor of the cable separate...
PVC stands for Polyvinyl Chloride, a type of plastic commonly used in construction and electrical applications.
PVC is a versatile material known for its durability and resistance to chemicals.
It is commonly used in electrical wiring, plumbing pipes, and vinyl flooring.
PVC is lightweight, easy to install, and cost-effective compared to other materials.
Examples of PVC products include PVC pipes, PVC electrical conduits,
The motor work in AC is based on electromagnetic induction, while in DC it is based on the Lorentz force principle.
AC motors work on the principle of electromagnetic induction, where a changing magnetic field induces a current in the rotor coils.
DC motors operate based on the Lorentz force principle, where a current-carrying conductor in a magnetic field experiences a force.
Examples of AC motors include induction motor...

A short circuit can be diagnosed by checking for signs of damage, using a multimeter, and tracing the circuit.
Check for signs of damage such as melted wires or blown fuses
Use a multimeter to test for continuity and resistance
Trace the circuit to locate the point of the short circuit
Isolate the affected area and repair or replace damaged components
Fundamental and controlling system
The device that is very sensational in low voltage protective system is a Ground Fault Circuit Interrupter (GFCI).
Ground Fault Circuit Interrupter (GFCI) is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.
GFCIs are commonly used in areas where water and electricity may come into contact, such as bathrooms, kitchens, and outdoor outlets.
They work by constantly mo...
Yes, you should check for a possible short circuit or reversed polarity.
Check for a possible short circuit in the wiring
Check for reversed polarity in the electrical connections
Ensure proper grounding of the system
Verify the connections at the distribution board
Consult with a senior electrician if unsure
The 10 safe methods when working on an electrical panel include proper training, de-energizing the panel, using appropriate PPE, and following lockout/tagout procedures.
Ensure you are properly trained and qualified to work on electrical panels.
Always de-energize the panel before starting any work.
Use appropriate personal protective equipment (PPE) such as insulated gloves and safety glasses.
Follow lockout/tagout proced...
The suitable cable size for a 15 Hp induction motor would typically be around 10 mm.
The cable size for a motor depends on factors like the motor's power rating, voltage, and distance from the power source.
For a 15 Hp motor, a cable size of around 10 mm would be suitable to handle the power requirements.
It is important to consult with a qualified electrician or refer to the motor manufacturer's guidelines for the exact
A motor is a device that converts electrical energy into mechanical energy to produce motion.
Motors are commonly used in various applications such as industrial machinery, household appliances, and vehicles.
There are different types of motors including AC motors, DC motors, and servo motors.
Motors consist of a rotor, stator, and various components such as coils, magnets, and brushes.
Examples of motors include electric
ACB stands for Air Circuit Breaker, a type of circuit breaker that operates in the air instead of oil or gas.
ACB is used to protect electrical circuits from overloads and short circuits.
It automatically cuts off the power supply when a fault is detected.
ACBs are commonly used in industrial and commercial buildings.
Examples of ACB manufacturers include Siemens, Schneider Electric, and ABB.
