Te māramatangaNgā RCCB me ngā MCBNgā Wāhanga Matua o te Haumaru Hiko
I roto i te ao o ngā whakaurunga hiko, he mea tino nui te haumaru. E rua ngā wāhanga matua e whai wāhi nui ana ki te whakarite i te haumaru hiko ko ngā kaiwawao iahiko toenga (RCCB) me ngā kaiwawao iahiko iti (MCB). He rerekē ngā mahi a ēnei taputapu e rua engari he maha ngā wā ka whakamahia ngātahi hei whakarato i te tiaki whānui mai i ngā hapa hiko. Ka tirohia e tēnei tuhinga ngā mahi, ngā rerekētanga, me te hiranga o ngā RCCB me ngā MCB i roto i ngā pūnaha hiko hou.
He aha te RCCB?
Ko te RCCB, arā, te kaiwawao ara iahiko toenga, he taputapu haumaru i hangaia hei ārai i te ru hiko me ngā ahi hiko i puta mai i ngā hapa whenua. Ka mahi mā te aroturuki i te taurite o te iahiko e rere ana i roto i ngā waea ora me ngā waea kūpapa. I raro i ngā āhuatanga noa, me ōrite te iahiko i roto i ngā waea e rua. Heoi, ki te puta he hapa, pērā i te turuturu nā te ngoikore o te whakamarumaru, te pā rānei o tētahi ki te waea ora, ka kitea e te RCCB tēnei taurite kore. Ina kitea he rerekētanga, he iti iho i te 30 mA te nuinga, ka motu, ka tapahia te hiko tata tonu.
He mea nui ngā RCCB i ngā taiao e nui ake ai te mōrearea o te ru hiko, pērā i ngā wharepaku, ngā kīhini me waho. He paparanga tiaki nui ēnei, inā koa mō ngā rōpū ngoikore pērā i ngā tamariki me ngā kaumātua.
He aha te MCB?
Ko ngā MCB (ngā kaiwawao hiko iti), i tētahi atu taha, he mea hanga hei tiaki i ngā hiko mai i ngā taumaha rawa me ngā poto poto. Kāore i rite ki ngā RCCB, e aro ana ki te turuturu, ka aroturukihia e ngā MCB te ia e rere ana i roto i te hiko. Mena ka nui ake te ia i te kaha kua whakatauhia o te MCB nā te taumaha rawa (hei tauira, he maha rawa ngā taputapu e whakamahia ana i te wā kotahi) he poto poto rānei (he hapa e hanga ana i te ara ātete iti), ka whati te MCB ka whakatuwhera i te hiko.
He mea nui ngā MCB hei ārai i te kino o ngā taputapu me ngā waea hiko, hei whakaiti hoki i te mōrearea o ngā ahi hiko nā te wera nui. He mea whakamahi noa ēnei i roto i ngā papa whakawhiti hiko kāinga me ngā papa whakawhiti hiko arumoni hei whakarite kia mahi ngā ara iahiko i roto i ngā rohe haumaru.
Ngā rerekētanga matua i waenga i te RCCB me te MCB
Ahakoa he wāhanga nui ngā RCCB me ngā MCB o te haumaru hiko, he rerekē ā rāua mahi:
1. Mahi: Ka whakamahia te RCCB hei tiaki i te hē whenua me te ru hiko, ko te MCB ia hei tiaki i te taumaha rawa me te ara iahiko poto.
2. Te Whakahaere: Ka motu te hiko RCCB nā te kore taurite o te iahiko, me ngā motu o te MCB nā te nui rawa o te iahiko.
3. Whakamahinga: Ko te RCCB e whakamahia whānuitia ana i ngā wāhi e nui ake ai te mōrearea o te ru hiko, ko te MCB ia e whakamahia ana hei tiaki i ngā ara iahiko mai i te taumaha rawa.
Te hiranga o te whakamahi i te RCCB me te MCB
Mō te haumaru hiko tino pai, e taunakihia ana kia honoa te RCCB me te MCB i roto i te raupapa. Mā tēnei huinga ka whakaratohia he parenga whānui mai i ngā hapa whenua me ngā taumahatanga o te ara iahiko. I roto i tētahi tāutanga hiko noa, ka tiakina e te MCB te ara iahiko mai i ngā taumahatanga, ā, mā te RCCB ia e whakarite kia kitea, kia tere hoki te whakahaere i tētahi iahiko turuturu.
Hei whakarāpopototanga, he wāhanga nui ngā RCCB me ngā MCB o ngā pūnaha hiko hou, ā, he mahi motuhake tā rāua ki te tiaki i a rātou mai i ngā tūponotanga hiko. He mea nui te mārama ki ō rāua mahi me ō rāua rerekētanga mō te hunga katoa e uru ana ki te tāutanga hiko, ki te tiaki rānei. Mā te whakamahi i ngā taputapu e rua, ka taea e ngā kaipupuri whare me ngā pakihi te whakapai ake i tō rātou haumaru hiko me te tiaki i te ora me ngā taonga mai i ngā tūponotanga o ngā hapa hiko.
