built-in appliance: fixed appliance intended to be installed in a cabinet, in a prepared recess in a wall or in a similar location. Here, because the appliance must be installed in a reserved position (usually a cubic space with only one side open), it is a fixed installation and can be regarded as a fixed…
fixed appliance: appliance that is intended to be used while fastened to a support or while secured in a specific location. The definition emphasizes fastening to a bracket or fixing in a specific position. Generally, we think that this kind of fixation requires some installation actions and some fixing devices, these devices can be fixed…
stationary appliance: fixed appliance or an appliance which is not a portable appliance. Stationary appliance includes fixed appliance and not a portable appliance.

hand-held appliance: portable appliance intended to held in the hand during normal use. Hair dryers, electric irons, hand-held vacuum cleaners, etc. are typical examples of hand-held appliances.
portable appliance: appliance that is intended to be moved while in operation or an appliance, other than a fixed appliance, having a mass less than 18 kg. This item is relatively easy to understand. Products that are less than 18kg are relatively light, so they are easy to move during operation, including humidifiers, fans, air…
protective extra-low voltage circuitportable appliance => portable appliance: earthed circuit operating at safety extra-low voltage which is separated from other circuits by basic insulation and protective screening, double insulation or reinforced insulationNOTE 1 Protective screening is the separation of circuits from live parts by means of an earthed screen.NOTE 2 A protective extra-low voltage circuitportable appliance => portable appliance…
i-transformer yokuphepha ehlukanisayo: i-transformer, okokufaka okujikajikayo okuhlukaniswa ngogesi kusukela ekujikeni kokuphumayo ngesimbobo okungenani esilingana nokufakwa okuphindwe kabili noma ukwahlukanisa okuqinisiwe, okuhloselwe ukunikeza into esetshenziswayo noma isekethe ku-voltage ephephile ephansi kakhulu I-transformer okukhulunywe ngayo lapha isetshenziselwa ukuhlinzeka ngamandla ezintweni ezisetshenziswayo noma kumasekhethi. Ama-transformer amaningi ajwayelekile ahlinzeka ngamandla kumasekhethi, futhi ambalwa anikezela ngamandla ezintweni zikagesi. Okubalulekile lapha…
safety extra-low voltage: voltage not exceeding 42 V between conductors and between conductors and earth, the no-load voltage not exceeding 50 V When safety extra-low voltage is obtained from the supply mains, it is to be through a safety isolating transformer or a convertor with separate windings, the insulation of which complies with double insulation…
i-voltage ephansi kakhulu: i-voltage ehlinzekwa isuka emthonjeni ongaphakathi kwento kagesi engeqi ku-50 V phakathi kwamakhondakta naphakathi kwamakhondakta nomhlaba lapho into esetshenziswayo inikezwa nge-voltage elinganiselwe I-voltage ephumayo yamabhethri ajwayelekile e-alkaline asendlini, i-voltage esebenzayo yesekethe ye-voltage ephansi ngemva kwe-transformer noma isekethe eyehlayo ye-RC ebhodini lesekethe yokulawula yezinto zikagesi ezijwayelekile zasendlini, konke okungachazwa ngokuthi amandla kagesi aphansi kakhulu….
