Ngā mea e 4 hei aro atu māu ina whakamahi ana koe i te RCBO

Ina tae ki te haumaru hiko, ko te hiranga o te whakamahi i tētahiRCBO (Kaiwawao Ara Iahiko Toenga me te Parenga Iahiko Nui) kāore e taea te whakanui rawa. Kua hangaia tēnei taputapu nui hei tiaki i ngā kaimahi mai i te ru hiko mēnā ka pakaru te turuturu o te taputapu, kia mau ai te haumaru o te tangata i roto i ngā taiao noho me ngā taiao arumoni. Nā ōna āhuatanga tiaki taumaha me te ara iahiko poto, he wāhanga nui ngā RCBO i roto i tētahi pūnaha hiko. Heoi, he maha ngā mea matua hei maumahara i te wā e whakamahi ana i te RCBO hei whakarite i tōna mahi me tōna whai huatanga tino pai.

Tuatahi, he mea nui kia aro nui ki te uara o te iahiko whakahaere toenga kua whakatauria o te RCBO. Ina tāutahia he parenga whakahaere iahiko whakahaere toenga i waenga i te parenga whānui me te parenga whakamutunga, me noho tōna uara iahiko whakahaere toenga kua whakatauria ki roto i te awhe o ngā parenga whakahaere iahiko whakahaere toenga taumata o runga me raro. Ko te rerekētanga o te taahiraa me noho i waenga i te 1.2 me te 2.5 ngā wā hei whakarite i te whakahaere maeneene me te whai hua o te RCBO i roto i te pūnaha hiko.

Haunga te uara o te iahiko whakahaere toenga kua whakatauria, he mea nui anō hoki kia whakaarohia te iahiko whakahaere toenga kua whakatauria mōrahi o te parenga katoa. I te wā kāore i te ua, kaua te iahiko whakahaere toenga kua whakatauria mōrahi e neke ake i te 75-100mA, ā, i te wā ua, kaua e neke ake i te 200-300mA. Mō ngā tono whare, kaua te uara o te iahiko whakahaere o te parenga whakahaere iahiko toenga e neke ake i te 30mA hei whakarato i te parenga pa tika mō ngā tāngata takitahi. Hei tāpiri, ina whakamahia te RCBO mō ngā taputapu hiko pūkoro me ngā taputapu hiko rangitahi, me 30mA anō hoki tōna uara o te iahiko whakahaere.

Ko tētahi atu mea nui hei whakaaroaro mā te whakamahi i te RCBO ko te tāutanga tika me te whakapūmau i ngā taputapu. Mō te tiaki whānui o ngā whatunga hiko iti-ngaohiko, me hono tika te pūwāhi kūpapa o te whakawhiti hiko ki te whenua. He mea nui kia whakarite kia kaua te arataki kūpapa whatunga e whakapūmau takiruatia, ā, kia mau tonu te taumata whakamarumaru rite tonu ki ngā arataki ā-wāhanga. Hei tāpiri, me ārai te tikanga tāutanga o te parenga mahi iahiko toenga i te tohatoha i te raina kūpapa me te raina ā-wāhanga ki ētahi atu ara iahiko kia pai ai te mahi a te RCBO.

Hei whakamutunga, me āta whakaarohia te tohatoha kawenga hiko ina whakamahia ana te RCBO, inā koa ngā kawenga kotahi-wāhanga. He mea nui kia tohatohahia te rama me ētahi atu kawenga hiko kotahi-wāhanga ki runga i ngā raina hiko toru-wāhanga. Mena he nui te rerekētanga, me whakatikatika kia ōrite ai ngā ia turuturu o ia wāhanga kia pai ai te mahi a te RCBO. Hei tāpiri, ina he raina whenua ngā raina ngaohiko iti, me rite te roa o ngā wāhanga e toru kia taurite ai te tohatoha o te kawenga hiko.

Hei whakarāpopototanga, he mea nui te whakamahinga tika o ngā RCBO mō te haumaru me te tiaki hiko. Mā te aro ki te uara o te iahiko whakahaere toenga kua whakatauria, te iahiko whakahaere toenga kua whakatauria mōrahi, te tāutanga me te tūhonohono, me te tohatoha o ngā kawenga hiko, ka taea e ngā tāngata te whakarite kia pai te mahi a te RCBO i roto i tā rātou pūnaha hiko. Nā tō rātou kaha ki te tiaki i a rātou mai i te ru hiko me te rahunga o ngā taputapu, he wāhanga nui ngā RCBO ki te pupuri i tētahi hanganga hiko haumaru me te pono.
