Pakaru ara iahiko toenga me te tiaki taumahate whakarite i te haumaru hiko
He mea nui ngā parenga hiko toenga (RCBO) me te tiaki taumaha rawa i roto i ngā pūnaha hiko kua hangaia hei tiaki i ngā hapa hiko me ngā taumaha rawa. Ka whakakotahi i ngā mahi a te taputapu au toenga (RCD) me te parenga hiko iti (MCB) ki roto i te wae kotahi, e whakarato ana i te tiaki whānui mai i te turuturu me te au nui rawa. He mea nui tēnei taputapu auaha ki te whakarite i te haumaru hiko i roto i ngā taiao noho, arumoni me te ahumahi.
Ko te mahi matua a te RCBO he kite i ngā taurite kore o te iahiko i puta mai i ngā hapa o te whenua, pērā i te pā atu o ngā tāngata ki ngā kaiārahi ora, ki ngā taputapu pakaru rānei. Mēnā ka puta he hapa pēnei, ka tere te whakatuwheratanga o te ara iahiko e te RCBO, ka ārai i te ru me te tūponotanga o te mate hiko. He mea nui rawa tēnei āhuatanga i ngā wāhi e tata ana ngā taputapu hiko ki te wai, pērā i ngā kīhini me ngā kaukau, nā te mea ka taea te whakaiti i te tūponotanga o tētahi aituā.
Haunga te tiaki i ngā hapa whenua, ka tiakina hoki e ngā RCBO ngā ara iahiko mai i ngā taumaha rawa me ngā ara iahiko poto. Mā te aroturuki i te rere o te iahiko, ki te kitea he iahiko nui rawa, ka taea te whakakore wawe i te ara iahiko, ka ārai i te kino o ngā waea me ngā taputapu, me te whakaiti i te tūponotanga o te ahi. Nā tēnei mahi takirua ka waiho te RCBO hei taputapu haumaru nui, e whakarato ana i te tiaki whānui ki ngā momo tūponotanga hiko.
Ko tētahi o ngā painga matua o te RCBO ko tōna kaha ki te whakarato i te tiakitanga takitahi mō ia ara iahiko. Kāore i rite ki ngā RCD tuku iho e tiaki ana i ngā taputapu katoa i runga i te ara iahiko kotahi, ka taea te tāuta i ngā RCBO ki runga i ngā ara iahiko motuhake, kia taea ai te tiakitanga kua tohua. Ko te tikanga o tēnei, ki te puta he hapa, ko te ara iahiko e pāngia ana anake ka momotu, ka whakaiti i te whakararuraru ki te toenga o te pūnaha hiko. He tino whai hua tēnei taumata o te tika i roto i ngā taiao arumoni me ngā taiao ahumahi e tino hiahiatia ana te haere tonu o te hiko.
Hei tāpiritanga, mā te ārai taumaha kua whakauruhia ki roto i te RCBO ka kore e hiahiatia he MCB motuhake, ka hua ake he papa tohatoha kua māmā ake, ā, he penapena wāhi hoki. Ehara i te mea ka whakaitihia te wā tāutanga me ngā utu anake, engari ka whakangāwarihia hoki te tiaki me te rapurongoā nā te mea he iti ake ngā wāhanga hei whakahaere. Nā te hoahoa kiato o te RCBO he mea tino pai hoki mō te whakauru ki ngā pūnaha hiko o nāianei, he huarahi māmā me te whai hua ki te whakapai ake i ngā mahi haumaru.
I te wā e whiriwhiri ana i tētahi RCBO, he mea nui kia whakaarohia ngā whakaritenga motuhake o te pūnaha hiko, tae atu ki te momo ara iahiko, te taumata aro e hiahiatia ana mō te kimi hapa whenua, me te whakatauranga iahiko mōrahi. He mea nui anō hoki kia whakarite kia tutuki te RCBO i ngā paerewa me ngā ture haumaru e tika ana hei whakapūmau i tōna pono me tōna mahi.
Hei whakarāpopototanga, he taputapu haumaru nui te pūwāhi hiko toenga me te tiaki i te taumaha rawa e whai wāhi nui ana ki te ārai i ngā tūponotanga hiko. Nā tōna kaha ki te kite i ngā hapa whenua me ngā taumaha rawa, me tōna tiaki hiko takitahi me te hoahoa penapena wāhi, ka waiho hei wāhanga nui i roto i ngā whakaurunga hiko. Mā te whakauru i ngā RCBO ki roto i ngā pūnaha hiko, ka taea te whakaiti i te tūponotanga o te ru hiko, te ahi, me te kino o ngā taputapu, ka whakarato i tētahi taiao haumaru ake mō ngā tono kāinga me ngā tono arumoni.
