Electrical work means installing, removing, adding, testing, replacing, repairing, changing, or maintaining electrical equipment or an electrical installation; or connecting or disconnecting electricity supply wire to and from electrical equipment
Lighting Fixture or luminaire is a component of electrical equipment with a light-producing electric lamp within. A fixture body and one or more lamps are components of any light fixture.
Explosion proof lighting:
Explosion proof lighting refers to lighting devices with the capacity to confine sparks that may otherwise ignite the explosive and flammable gases in the atmosphere.
Breakers & Contactors:
A circuit breaker is a type of electrical switch used to guard against short circuits, overloads, and overcurrent that might harm an electrical circuit. Its primary purpose is to halt current flow when protective relays identify a defect.
A contactor’s main job is to connect a load to a current flow, and that load should have a high voltage. The contactor has advantages as well because of how rapidly it can release and shut. When control is necessary or a transition between high and low voltage is needed, a moving contactor is needed.
Small loads linked by a cable and plug, such as televisions, fans, and vacuums, are permitted on general-use circuits as long as the power they consume does not exceed the circuit’s capacity. These circuits are primarily designed for lighting. Illumination and light loads.
The provision of electrical protection against the thermal and mechanical strains of short circuit currents is a crucial function of low voltage switchgear. This is essential for preventing the installation from being damaged by high currents and for isolating the problematic current from the other components.
Electrical cables, raceways, and insulated conductors used for electric power distribution, control, signal instrumentation, and communication are mechanically supported by cable trays, which offer a solid structural framework. Aluminum, stainless steel, and galvanized steel are the materials used to make metal cable trays.
Their name comes from the fact that pull boxes are used with conduit to make electrical installation simpler. They are able to draw conductors across great distances without putting an undue pressure on the wire or insulation because they are constructed of sheet metal, cast metal, or a non-metallic substance.
A distribution board, also referred to as a panelboard, breaker panel, electric panel, DB board, or DB box, is a part of an electricity supply system that separates an electrical power feed into subordinate circuits and provides a protective fuse or circuit breaker for each circuit in a single enclosure.
The act of sending electricity straight to the earth is known as earthing. Low resistance cable or wires are used to accomplish this. In other words, earthing is done to safeguard people’s safety by shielding them from electric shocks. Different earthing techniques exist.
