Answer:
An electrical appliance is defined within BS 7671 as:
‘An item of current-using equipment, other than a luminaire or an independent motor’
An appliance, in the general sense, is an electrical or mechanical machine that accomplishes a specific function.
Appliances are normally encountered in domestic, commercial, or industrial applications, although generally the term is applied to equipment often found in dwellings and commercial environments.
Electrical appliances are often split into three categories:
Consumer electronics – such as television, audio, IT, data processing, etc.
Small appliances – such as electric kettles, toasters, hair driers, beverage makers, etc.
Larger appliances – such as refrigeration, cooking, laundry equipment, etc.
Electrical appliances within buildings may range from handheld or portable items to items designed for use in a fixed position.
Whilst such appliances are often connected to the electricity supply utilizing a flexible cable and plug and socket arrangement, some may be permanently wired into the electricity supply.
Often, apart from appliances for use in private dwellings, electrical appliances need to be subject to routine testing and inspection, to provide continued safety assurance. Such regimes are known as ‘PAT testing’ and are put in place to meet obligations under the Electricity at Work Regulations 1989.
