• Keeping work areas clean and free of clutter to prevent tripping hazards

• Traini...read more

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Consists of two or more coils of insulated wire wound around a core

• Primary coil receives electrical energy and induces a magnetic field in the core

• Secondary coil receives the magnetic field and converts it back to electrical energy

• Used to step up or step down voltage levels in electrical...read more

ACB stands for Air Circuit Breaker, which is a type of circuit breaker that operates in the air to protect electrical circuits from overloads and short circuits.

• ACB is commonly used in low voltage applications to protect electrical equipment.

• It automatically cuts off the power supply when it detects an overload or short circuit.

• ACBs are available in different sizes and ratings to suit various applications.

• Examples of A...read more
