Te rerekētanga i waenga i te MCB me te MCCB

E rua ngā momo pūwhakawhiti hiko e whakamahia whānuitia ana i roto i ngā momo mahi:ngā kaiwawao ara iahiko kua whakarewaina (MCCB) mengā whati ara iahiko iti (MCBHe wāhanga nui ēnei e rua i roto i ngā pūnaha hiko, e whakarato ana i te tiaki mai i ngā taumahatanga me ngā ara iahiko poto. Heoi, he rerekētanga nui kei waenganui i ēnei momo ara iahiko e rua, ā, he mea nui te mārama ki ēnei rerekētanga hei whiriwhiri i te hua tika mō tētahi tono motuhake.

Ko te mahi matua a te MCCB he whakarato i te tiaki i te taumaha me te ara iahiko poto i roto i ngā pūnaha tohatoha ngaohiko iti me ngā ara iahiko tiaki motuka. E mōhiotia ana rātou mō tō rātou pono me te pumau, ā, he mea rongonui i roto i ngā taiao ahumahi. I tetahi atu ringa, ka whakamahia ngā kaiwawao ara iahiko iti hei whakarato tiaki i ngā wae tohatoha hiko i roto i ngā whare. Ahakoa he kaiwawao ara iahiko, he rerekētanga kei waenganui i ngā MCCB me ngā MCB me whai whakaaro i te wā e whiriwhiri ana i te hua tika mō tētahi tono motuhake.

Tuatahi, me tutuki ngā pakaru hiko tauira me ngā pakaru hiko iti i ngā paerewa hua taketake, ā, me rite tonu te kaupapa mahi ki ngā pakaru hiko. Engari he rerekētanga mārama kei waenganui i ngā mea e rua e pā ana ki ngā tawhā hiko me ngā tawhā miihini me ngā taiao mahi e tika ana.

Ko tētahi o ngā rerekētanga matua i waenga i te MCCB me te MCB ko ngā tawhā hiko ka taea e rāua te whakahaere. Ko te whakatauranga o te MCCB tae atu ki te 2000A, he pai mō ngā rūma nui me ngā kawenga hiko taumaha. Ko ngā MCB, i tētahi atu ringa, he 125A te whakatauranga au mōrahi, e whakawhāiti ana i tō rātou kaha, ā, he pai ake mō ngā tono iti ake. Ko te tikanga o tēnei rerekētanga o ngā whakatauranga au he pai ake ngā MCCB mō ngā taiao ahumahi me ngā taiao arumoni kei reira ngā kawenga hiko nui ake, ko ngā MCB ia e whakamahia ana i ngā taiao noho me ngā taiao arumoni iti.

Haunga ngā tawhā hiko, he rerekētanga anō hoki ngā tawhā miihini i waenga i te MCCB me te MCCB. Hei tauira, he matotoru ake ngā waea e hono ana ki te MCCB, ā, neke atu i te 35 mita pūrua te whānui. He rerekē, kua hangaia te MCB hei whakamahi i ngā waea iti ake, ā, he pai mō ngā wāhi tae atu ki te 10 mita pūrua. Ko te tikanga o tēnei rerekētanga miihini he pai ake te MCCB mō te whakahaere i ngā pūnaha hiko nui, ko te MCB ia he pai ake mō ngā tono iti ake.

Ko tētahi atu mea nui hei whakaaroaro ko te taiao mahi. Kua hangaia ngā MCCB hei whakamahi i roto i te whānuitanga o ngā taiao, tae atu ki ngā taiao ahumahi me ngā taiao arumoni. Ka taea e rātou te tu atu ki ngā kawenga hiko taumaha ake, ā, he pakari ake, he pai mō ngā tono e tino hiahiatia ana te pono. Ko ngā MCB, i tētahi atu taha, kua hangaia hei whakamahi i roto i ngā pūnaha tohatoha hiko hanga whare, ā, he pai ake mō ngā taiao noho me ngā taiao arumoni iti.

Hei whakarāpopototanga, ahakoa he wāhanga nui te MCCB me te MCB i roto i ngā pūnaha hiko, he rerekē ngā whakamahinga o ēnei, ā, he rerekētanga nui kei roto i ō rāua tawhā hiko me ā rāua tawhā miihini. He mea nui te mārama ki ēnei rerekētanga hei whiriwhiri i te hua tino tika mō tētahi whakamahinga motuhake, ahakoa he taiao ahumahi, arumoni, noho rānei. Mā te whakaaro ki ngā āhuatanga pēnei i te whakatauranga o nāianei, ngā tawhā miihini me te taiao whakahaere, ka taea te whakatau whai whakaaro i te wā e whiriwhiri ana i ngā MCCB me ngā MCB mō tētahi pūnaha hiko motuhake.
