Whakamōhio mai:
He mea nui te mahi a ngā kaiwawao hiko hei whakarite i te haumaru o te hiko. Ka ārai i ngā taumahatanga, ngā ara iahiko poto me ngā hapa hiko, ka tiaki i ngā oranga me ngā taputapu hiko whai hua. I roto i tēnei tuhinga, ka tirohia hohonutia e tātou te ao o ngā kaiwawao hiko, me te arotahi ki ngā rerekētanga me ngā mahi a te RCCB, te MCB me te RCBO.
1. Ngā mōhiotanga taketake mō ngā pūwā hiko:
I mua i te ruku hohonu ki ngā taipitopito, me mārama tātou he aha te mea he whati hiko. Ko te tikanga, he pana aunoa te whati hiko e āwhina ana ki te tiaki i ngā hiko mai i ngā kino i puta mai i te nui o te iahiko. Ina taumaha rawa, ina poto rānei te hiko, ka motuhia te rere o te hiko e te whati hiko, ka ārai i ngā tūponotanga kino pēnei i ngā ahi hiko.
2. Pūwhakawhiti ara iahiko iti (MCB):
Ko ngā MCB ngā mea e whakamahia whānuitia ana i roto i ngā wāhi noho me ngā wāhi arumoni. Ko ēnei taputapu iti engari pakari, he mea hanga tuatahi hei tiaki i te iahiko nui rawa atu nā te taumaha rawa, te iahiko poto rānei. Kei te wātea ngā MCB i roto i ngā momo whakatauranga iahiko, e āhei ai te whakaritenga kia tutuki ai ngā whakaritenga hiko rerekē. Ka taea te tautuhi anō ā-ringa i muri i te pakaru, he mea watea mō te whakamahi i ia rā.
3. Te whati ara iahiko toenga (RCCB):
Ko ngā RCCB, e mōhiotia ana ko ngā Pūrere Iahiko Toenga (RCD), ka whakarato i tētahi atu paparanga haumaru mā te kimi me te ārai i ngā iahiko turuturu whenua. Ka puta ēnei iahiko ina pā he aituā te kaiārahi hiko ora ki tētahi wāhanga kaiārahi hiko o tētahi taputapu hiko, pērā i tētahi pouaka whakarewa. Ka aroturukihia e te RCCB te iahiko e rere ana i roto i ngā waea ora me ngā waea kūpapa, ā, ka whati tonu mēnā ka kitea he taurite kore. Ka taea tēnei taurite te puta mai i te pā o te tangata ki tētahi taputapu hapa, ka whakaiti i te mōrearea o te hiko.
4. Te kaiwawao hiko toenga (RCBO) me te parenga iahiko nui:
Ka whakakotahi te RCBO i ngā āhuatanga o te MCB me te RCCB hei whakarato i te parenga takirua mai i te iahiko nui me te iahiko toenga. He kōwhiringa whai hua ēnei taputapu ina hiahiatia he tiaki i tētahi ara iahiko motuhake, i tētahi taputapu takitahi rānei mai i ngā hapa hiko. He maha ngā wā ka kitea te RCBO i ngā wāhi nui pērā i ngā kīhini me ngā kaukau, ina pā te wai ki te wāhi ka nui ake te mōrearea o ngā tūponotanga hiko. Hei tāpiri, ka taea e ngā RCBO te wehe i ngā ara iahiko takitahi i te wā e rapu raruraru ana, e tiaki ana rānei, me te pupuri tonu i te toenga o te tāutanga kia mahi tonu.
5. Ngā rerekētanga matua me ngā painga:
a) Ko te arotahi a te MCB ki te aukati i te nui rawa o te iahiko e puta mai ana i te taumaha rawa, i te ara iahiko poto rānei. He ngāwari ki te whakamahi, ka taea te tautuhi anō ā-ringa, ā, he whānuitia te whakamahinga nā te mea he iti te utu me te wātea.
b) Ka whakaratohia e te RCCB he parenga mai i ngā ia turuturu o te whenua e puta mai ana i te pā atu o te tangata ki ngā taputapu hapa, ki ngā waea pakaru rānei. Ka whakanui ake ēnei taputapu i te haumaru, ā, ka ārai hoki i ngā tūponotanga o te ru hiko.
c) He pai ngā painga o te RCBO i te MCB me te RCCB. Ka whakaratohia e rāua he parenga iahiko nui me te iahiko toenga, ā, he pai rawa atu mō ngā ara iahiko tairongo, ngā wāhi rānei e hiahia ana ki ngā tikanga haumaru tino pakari.
6. Tīpakohia te pūwhakawhiti ara iahiko e tika ana:
Ko te whiriwhiri i te kaiwawao hiko tika e whakawhirinaki ana ki ngā āhuatanga maha, pērā i te kawenga hiko, te aro o te hiko, me ngā whakaritenga haumaru motuhake. Me kōrero tonu ki tētahi tohunga hiko, ki tētahi miihini hiko rānei, ka taea e ia te arotake i ō hiahia me te taunaki i te momo kaiwawao hiko me te whakatauranga e tika ana mō tō tāutanga.
Hei whakarāpopototanga:
He mea nui te mārama ki ngā rerekētanga i waenga i ngā momo whati hiko pēnei i te RCCB, te MCB me te RCBO hei pupuri i te haumaru hiko i roto i ngā taiao noho, arumoni me ngā taiao ahumahi. Ka tiaki te MCB i te iahiko nui, ka tiaki te RCCB i ngā iahiko turuturu whenua, ā, ka whakarato te RCBO i te tiakitanga katoa i ngā iahiko e rua. Mā te whiriwhiri i te whati hiko tika mō tō pūnaha hiko, ka taea e koe te ārai i ngā tūponotanga kino me te whakarite i te haumaru o te tangata me ngā taputapu.
