Ka whakamahia e te kaihoroi tuanui he kaiwhakahaere kua whakaritea, a, ko te atanga mata pa e whakaatu ana i nga raraunga mahi a te kaiwhaiwhai i roto i te waa tuuturu, he pai mo te aro turuki ka taea te whakarereke tere kia rite ki nga hiahia.He ngawari te mahi, he waatea me te tere.He watea mo te whakatikatika i nga mahi tirohanga, kotahi-matua te whakatikatika tere o te tuanui, te whakawhiti whakamua me te whakamuri.Ko te punaha whakahaere he mea whakamarumaru mohio mo te overvoltage, undervoltage, overtemperature, overcurrent, waahanga ngaro, me te wiri.Mena he rereke te powhiriwhiri i te wa e mahi ana, ka kati te punaha i te waa.
● Ko nga waahanga hiko teitei, te tino kounga me te whakamatautau haumaru.
● Te kitenga o nga taputapu mo te mana mahi powhiriwhiri tuanui, te whakamarumaru i te wa-tūturu.
● Te mana pa o te mata, te whakaatu i te wa-tuuturu o te mana whakahaere, te whakarereke tere o te paatene kotahi, te whakamua me te whakamuri.
● Te whakamarumaru o te taputapu me te rorohiko rorohiko-te ngaohiko, i raro i te ngaohiko, i te tere, i te mahana, i te whakamarumaru i te wahanga mate, i te tukinga.
Maamaa te whakahaere powhiri tuanui, ka taea e te kaitoha kotahi te whakahaere i nga mahi a nga kaiwhaiwhai maha i te wa kotahi, he pai mo te whakahaere me te whakahaere o ia ra.
Ko te mana mohio kei roto ko te mana powhiri tuanui, te mana mamao, te mana aunoa, te whakahaere i te pāmahana me te makuku, me te whakahaere raraunga nui.
● Na roto i te wa me te whakamaarama i te pāmahana, kua tautuhia te mahere mahi.
● I te whakapai ake i te taiao, whakaitihia te utu o te hiko.
● Whakamahia te mata pa ki te mohio ki te mana whakahaere, ngawari me te watea, e tino pai ake ai te whakahaerenga mohio hou o te wheketere.
● Ko te mana mohio SCC ka taea te whakarite kia rite ki te whakahaerenga mohio o te wheketere a te kaihoko.
