It usually consists of an enclosure, a variety of electrical components, and often a power switch. Electrical devices include light bulbs, vacuums, toasters and older technologies such as the electric telegraph and batteries. Electrical devices are defined as devices that use or generate electricity and transform it into another form of energy, such as motion, heat or light. Appliances, Microcontrollers, Programmable logic controllers and Small appliances. Electrical equipment refers to components that are part of the electrical distribution system such as Electric switchboards, Distribution boards, Circuit breakers and Disconnects, Electricity meters, and Transformers.

Electrical equipment means any apparatus, appliance, cable, conductor, fitting, insulator, material, meter or wire that is used for controlling, generating, supplying, transforming or transmitting electricity at a voltage greater than extra-low voltage or is operated by electricity at a voltage greater than extra-low.

Electrical equipment includes any machine powered by electricity.

Examples of these include:

• Lighting.
• Major appliance.
• Small appliances.
• IT equipment (computers, printers etc.)
• Motors, pumps and HVAC Systems.

Components used in most printed circuit boards:

• Resistors. Resistors control the electric currents that pass through them, as well as the voltage in each component connected to them. ...
• Transistors
• Capacitors
• Inductors
• Diodes

Resistors

Resistors control the electric currents that pass through them, as well as the voltage in each component connected to them. Without resistors, other components may not be able to handle the voltage and this may result in overloading.

Transistors

Transistors are crucial to the printed circuit board assembly process due to their multi-functional nature. They are semiconductor devices that can both conduct and insulate and can act as switches and amplifiers. They are smaller in size, have a relatively long life, and can operate at lower voltage supplies safely without a filament current. Transistors come in two types: bipolar junction transistors (BJT) and field-effect transistors (FET).

Capacitors

Capacitors are passive two-terminal electronic components. They act like rechargeable batteries – they can store electrical energy and then transmit that energy again when needed.

Inductors

Inductors are passive two-terminal electronic components that store energy in a magnetic field when an electric current passes through them. Inductors are used to block alternating currents while allowing direct currents to pass. They can be combined with capacitors to make tuned circuits, which are used in radio and TV receivers.

Diodes

Diodes are semiconductor components that act as one-way switches for currents. They allow currents to pass easily in one direction but restrict currents from flowing in the opposite direction.

Telecoms

Telecommunications equipment is hardware which is used for the purposes of telecommunications. Since the 1990s the boundary between telecoms equipment and IT hardware has become blurred as a result of the growth of the internet and its increasing role in the transfer of telecoms data.

It includes a wide range of communication technologies, from transmission lines and communication satellites to radios and answering machines. Examples of telecommunications equipment include switches, telecom towers, fibre-optic cables, routers, voice over internet protocol (VoIP), and smartphones.
