RCD, RCCB, RCBO: Ngā Otinga Haumaru Hiko Matatau

RCD, RCCB me RCBO: Kia Mōhio ki ngā Rerekētanga

He taputapu hiko nui ngā RCD, ngā RCCB me ngā RCBO e whakamahia ana hei ārai i te mōrearea o te ru hiko me te ahi. Ahakoa he rite te tangi, he rerekē te mahi a ia taputapu, ā, he āhuatanga motuhake anō hoki. Te mārama ki ngā rerekētanga i waenga iRCD, RCCBmeRCBOhe mea nui hei whakarite i te haumaru hiko i roto i ngā taiao noho me ngā taiao arumoni.

Ko te RCD, he whakarāpopototanga mō te Pūrere Auaha Toenga, he taputapu haumaru i hangaia hei momotu tere i te hiko ina kitea he au turuturu i roto i te ara iahiko. Ka puta pea te turuturu hiko nā te waea hē, te rahunga o ngā taputapu, te pā tika rānei ki ngā wāhanga ora. He mea nui ngā RCD hei ārai i te ru hiko, ā, e whakamahia whānuitia ana i roto i ngā kāinga, i ngā tari me ngā wāhi ahumahi.

Ko te RCCB (arā, te Pūwhakawehe Ara Iahiko Toenga) he momo RCD i hangaia mō te tiaki i ngā hapa whenua. Ka aroturuki te RCCB i te kore taurite o te iahiko i waenga i ngā ara iahiko ora me te ara iahiko kore, ā, ka whakaweto i te ara iahiko ina kitea he turuturu whenua. Nā tēnei ka tino whai hua ngā RCCB ki te ārai i te ru hiko e puta mai ana i ngā hapa pūnaha hiko.

Ka whakakotahi te RCBO (kaiwawao iahiko toenga me te tiakitanga iahiko nui) i ngā mahi a te RCCB me te kaiwawao iahiko iti (MCB) i roto i te taputapu kotahi. Haunga te whakarato tiakitanga hapa whenua, ka whakaratohia hoki e te RCBO te tiakitanga iahiko nui, ko te tikanga ka taea e ia te whakaweto i te ara iahiko mēnā ka nui rawa te hiko, ka poto rānei te ara iahiko. Nā tēnei ka taea te whakamahi i ngā RCBO, ā, he pai hoki mō ngā momo tono, tae atu ki te tiaki i ngā ara iahiko takitahi i roto i ngā papa tohatoha.

Ko tētahi o ngā rerekētanga matua i waenga i ēnei taputapu ko tā rātou whakamahinga me te taumata tiaki e whakaratohia ana e rātou. Ko ngā RCD e whakamahia ana hei whakarato tiaki whānui mō te ara iahiko katoa, ko ngā RCCB me ngā RCBO ia e whakamahia ana hei tiaki i ngā ara iahiko motuhake, i ngā taputapu takitahi rānei. Hei tāpiri, he painga tāpiri tō ngā RCBO ko te tiakitanga iahiko nui, e waiho ana hei otinga whānui mō ngā hapa hiko maha.

Mō te tāutanga, he mea hanga ngā RCD, RCCB me te RCBO kia tāutahia e te tohunga hiko whai tohu. He mea nui te tāutanga tika kia pai ai te mahi a ēnei taputapu, kia tiakina hoki. He mea nui anō hoki te whakamātautau me te tiaki auau kia pai ai te mahi a ngā RCD, RCCB me ngā RCBO.

Hei whakarāpopototanga, he wāhanga nui ngā RCD, RCCB me te RCBO o ngā pūnaha haumaru hiko, ā, he kaupapa motuhake tā ia wāhanga hei ārai i te ru hiko me ngā tūponotanga ahi. He mea nui te mārama ki ngā rerekētanga i waenga i ēnei taputapu hei whiriwhiri i te parenga tika mō ngā tono rerekē. Ahakoa te whakamahi i te RCD mō te parenga whānui, i te RCCB mō te parenga hapa whenua, i te RCBO rānei hei whakakotahi i te parenga hapa whenua me te parenga iahiko nui, he mahi nui tā ēnei taputapu hei whakarite i te haumaru hiko i roto i ngā taiao noho me ngā taiao arumoni.
