Hei kaihanga kaukau kiriaku whakauru-ahumahi, FSPA (Foshan Gaoming BhoaE mārama ana a Technology Co., Ltd.) he nui atu i te aromatawai noa i te kounga o te hua te mahi hoko kaukau ā-ao—engari me aro nui ki ngā rerekētanga o te ngaohiko, te auau, me ngā hononga hiko, he mea nui ēnei ki te haumaru, te mahi, me te roa o te wā o te waeine. Mā te kore e aro ki ēnei rerekētanga hiko ā-rohe ka arahi pea ki te rahunga o ngā taputapu, te kore whai hua o te pūngao, tae atu ki ngā tūponotanga haumaru, ka waiho te whakawhitiwhiti kōrero matatau i waenga i ngā kaihoko me ngā kaihanga hei taahiraa kore e taea te whiriwhiri mō ngā tauwhitinga ā-ao.
He rerekē rawa ngā paerewa ngaohiko me te auau i waenga i ngā rohe, ā, ka pā tika ki ngā mahi matua o ngā wāhi kaukau. Ko Amerika Te Raki te nuinga e whakamahi ana i te 120V/240V i te 60Hz, ko Ūropi ia, te nuinga o Āhia, me Ahitereiria e whakawhirinaki ana ki te 220V-240V i te 50Hz. E tū pakari ana a Hapani me ā rātou paerewa takirua: 100V i te 50Hz (ngā rohe rawhiti) me te 60Hz (ngā rohe hauauru). Ko ngā wāhi kaukau, me ngā wāhanga e kaha ana te hiko pērā i ngā pūnaha whakamahana, ngā papu tohanga, me ngā jet whakaora wai, kua whakaritea mō ngā takirua ngaohiko-auau motuhake. Ko te wāhi kaukau 220V/50Hz e whakamahia ana i runga i te tuku 120V/60Hz ka iti te mana o ngā motuka—ka ngoikore ngā jet, ka puhoi te whakamahana, ka pakaru wawe ngā wāhanga—ko te waeine 120V/60Hz e hono ana ki te 240V/50Hz ka tūpono te wera tere o ngā papa hiko, ngā motuka rānei. I FSPA, ka whakatauhia tēnei mā te whakarite wawe i ngā pūnaha hiko: mō ngā ota o Kanata, ka whirihorahia e mātou ngā waeine whakamahana 220V/50Hz ki te 240V/60Hz, kia 3-4°C te whakamahana ia haora, me te kore e ngaro te whai huatanga.
Ka tāpirihia e ngā momo hononga hiko tētahi atu paparanga uaua, me te neke atu i te 15 ngā paerewa o te ao e rerekē ana i roto i te hoahoa titi, te whenua, me te kaha o te iahiko. Ka whakamahia e te US me Kanata te Momo A/B (e rua/toru ngā titi, kāore i te whenua/whenua), ka whakamahia e Ūropi te Momo C/F (e rua ngā titi porowhita whenua), ā, ka whakamahia e Ahitereiria te Momo I (e toru ngā titi papatahi koki). Me ōrite te taura hiko o te whare kaukau - he waea mārō, he mea wetewete rānei - ki te hononga o te wāhi e haere atu ana kia kore ai e wetekina ngā hononga, e piko ana, e wera rawa rānei. Hei tauira, me whai hononga kaha-nui te whare kaukau 30A pērā i te Momo L o Itari (16A-32A) hei utu mō te Momo A 15A paerewa. Ka whakauruhia e te FSPA te hototahitanga o ngā hononga hiko ki roto i ngā ota: mō ngā kiritaki hōtēra o Tai (ngā hononga Momo O, 220V/50Hz), ka tukuna e mātou he mono 16A me te whenua whakapakari, me ngā taunakitanga ara iahiko 30A mō ngā pūnaha whakamahana 5.5kW.
Ko te kī ki te angitu kei roto i te whakawhitiwhiti kōrero taipitopito i waenganui i te kaihoko me te kaihanga. I FSPA, ka tono mātou i ngā paerewa hiko ā-rohe (ngaohiko, auau, momo pūtukatuka) me ngā taipitopito tāutanga (noho/arumoni, ara iahiko motuhake) i te wā e whakaū ana i te ota. Mā tēnei ka taea e mātou te whakarerekē i ngā wāhanga me ngā āhuatanga haumaru—pērā i te tāpiri i ngā RCD e tutuki ana ki te VDE a Tiamana (te tapahi hiko 0.1-hēkona mō ngā turuturu)—me te āwhina i ngā kaihoko kāore i te tino mōhio ki ngā paerewa ā-rohe me ngā kaiārahi, ngā kōrerorero rānei ki ngā tohunga hiko. Ko tā mātou tauira whakauru ahumahi-tauhokohoko, e whakakotahi ana i te hanga ā-whare me te tirohanga mākete o te ao, ka whakarite kia mahi haumaru, kia whai hua hoki ia wāhi mirimiri puta noa i te ao. Mō ngā kaihoko o te ao, ehara i te mea he mea pai anake te whakawhitiwhiti kōrero mārama mō ēnei taipitopito hiko—koia te tūāpapa o tētahi haumitanga wāhi mirimiri kaukau pono.
