Tepouaka tohatohaHe taputapu matua i roto i te pūnaha hiko hei whakatutuki i te tohatoha, te whakahaere me te tiaki i te hiko, ā, e whakamahia whānuitia ana i roto i te hanga ahumahi, ngā whare arumoni, ngā miihini ā-tāone me ngā whare o waho me ētahi atu āhuatanga. I roto i ngā tipu ahumahi, ka whakaratohia he hiko pumau mō ngā taputapu toru-wāhanga pērā i ngā taputapu mīhini, ngā pā hau me ngā raina huihuinga. Ka whakamahia e ngā toa hokohoko, ngā whare tari me ngā pokapū raraunga hei whakatutuki i te tohatoha hiko kua wehea mō te rama, te hauhautanga me ngā taputapu rūma rorohiko. I ngā wāhi o waho pērā i te rama rori, ngā papa hanga, me te taurite puranga utu, he maha ngā wā ka whakamahia ngā pouaka tohatoha ātete ua me te ātete waikura hei whakarite i te mahi haumaru i te rangi tuwhera. Hei tāpiri, kāore e taea e ngā hapori noho, ngā awheawhe wheketere, me ngā kaupapa whakahoutanga hiko te noho me te kore he pouaka tohatoha mō te whakahaere pokapū hei whakarite i te tohatoha tika o ngā kawenga hiko me te whakatutuki i ngā whakaritenga mahi pumau o ngā taputapu hiko toru-wāhanga 480V.
Ko te hanganga o roto he whakatakotoranga ā-pūrua te nuinga, kei roto ko te tinana pouaka, te waeine raina e tomo mai ana, te waeine tohatoha, ngā wāhanga tiaki me te pūnaha waea. Ko te tinana pouaka he mea hanga ki te pereti maitai matao-hurihia, ki te maitai kore-waikura rānei. Ko te momo o waho he tohu tiaki NEMA 3R, ka taea te ārai i te ua, te puehu me ngā mea ke mai i te tomo. Ko te wāhanga raina e tomo mai ana he pana matua, me te kaiwawao hiko-teitei noa e mahi ana hei mana matua hei whakatutuki i te tiaki hiko whakaweto-whakaweto me te taumaha. I roto, ka tohatohahia te hiko mā roto i ngā pae pahi parahi. He maha ngā pana whati peka kua tāutahia, ā, kei ia peka he kaiwawao hiko hei whakarato i te tiaki poto-ara me te taumaha mō ngā raina peka. Kei te pouaka he pae waea kūpapa me ngā pae whenua hei whakarite i te haumaru hiko. I taua wā anō, ka rahuihia he wāhi waea whaitake, ā, kua whakaritea ngā taura i roto i te huarahi paerewa hei whakaiti i te pokanoa me ngā mōrearea hapa. He kiato te hanganga whānui, ā, he pono te tiaki. Ehara i te mea ka taea anake te whakatutuki i te putanga hiko maha-hongere engari ka taea hoki te whakahaere i te tiaki me te whakatika tere, me te whakarite i te tuku hiko tonu me te pumau i roto i ngā āhuatanga rerekē.
