Taitara: Kia Mōhio ki te Rerekētanga i waenganui iNgā Wāhi Whakamutu Arahiko ItimeNgā Wāhi Whakarewahia o te Ara Iahiko
He wāhanga nui ngā kaiwawao hiko o te pūnaha hiko o tētahi whare. Ka āwhina ēnei ki te tiaki i tō whare, tari, rawa pakihi rānei mai i ngā taumaha hiko me ngā ara iahiko poto. E rua ngā kaiwawao hiko e whakamahia whānuitia ana ko te kaiwawao hiko iti (MCB) me te whati ara iahiko pouaka kua whakakikoruatia (MCCBAhakoa he rite tonu te kaupapa o ēnei e rua, he rerekētanga anō kei waenganui i a rāua. I roto i tēnei tuhinga, ka tūhuratia ēnei rerekētanga.
1. Rahi me te whakamahinga
Ko te rerekētanga matua i waenganui iMCBmeMCCBko tōna rahi. E ai ki te ingoa, he iti ake te rahi o ngā MCB, ā, e whakamahia ana i roto i ngā tono au iti tae atu ki te 125 amps. He mea noa te whakamahi i roto i ngā tono kāinga me ngā tono arumoni iti. Ko ngā MCCB ia, he nui ake, ā, ka taea te whakahaere i ngā kawenga au teitei ake tae atu ki te 5000 amps. He mea noa te whakamahi i roto i ngā tono ahumahi me ngā tono arumoni e hiahia ana ki te nui o te mana.
2. Kaha, ā, pakari
He kaha ake, he pakari ake hoki te MCCB i te MCB. Ka taea e rātou te tu atu i ngā taumahatanga hiko nui ake, ā, kua hangaia kia tū atu ki ngā taiao uaua.Ngā MCCBhe mea hanga i te nuinga o te wā ki tētahi rauemi kaha ake pērā i te uku, i te kirihou whakarewa rāneiNgā MCB, he mea hanga i te nuinga o te wā ki te whare kirihou. Kua hangaia ngā MCB mō te whakamahi i roto i ngā taiao kāore i te tino kino, ā, kaua e tūtaki ki ngā rauemi tino waikura, ki ngā pāmahana tino kino rānei.
3. Tikanga tūtaki
Ngā MCB me ngāNgā MCCBkua hangaia kia motumotuhia ina neke atu te ia i tētahi rohe. Heoi, he rerekē ngā tikanga e whakamahia ana e rātou hei motumotu. He tikanga motumotu aukume wera tō te MCB. Ka whakamahia e te tikanga he rīpene whakarewa-rua e wera ana, e piko ana hoki ina neke atu te ia i tētahi paepae, ka motumotuhia te kaiwawao ara iahiko. He tikanga motumotu hiko tō te MCCB e whakamahi ana i tētahi tukatuka iti hei tātari i te rere o te iahiko. Kia neke atu te ia i te paepae, ka tukuna e te tukatuka iti he tohu ki te kaiwawao ara iahiko hei motumotu.
4. Te utu
Ngā MCBhe iti ake te utu i te nuinga o te wāNgā MCCBNā te mea he māmā ake te hoahoa, ā, he iti ake te utu o ngā rauemi i hangaia ai. He iti ake hoki te pakari o ēnei i ngā MCCB, ā, he iti ake te kaha kawe iahiko. He nui ake te utu o ngā MCCB nā te uaua o te hoahoa me ngā rauemi i whakamahia, engari he pakari ake, ā, ka taea te tu atu ki ngā kawenga iahiko teitei ake.
5. Te Tiaki
Ko te tiaki e hiahiatia ana mō ngā MCB meNgā MCCBHe tino rerekē. He māmā noa te hoahoa o te MCB, ā, kāore e hiahiatia he tiaki nui. Me tirotiro tonu e te tohunga hiko, ā, me whakakapi mēnā he hapa. Ko ngā MCCB ia, me nui ake te tiaki, pērā i te tirotiro auau i ngā waeine hiko, ka tawhito pea i roto i te wā, ā, me whakakapi.
Hei whakarāpopototanga, ko MCB meMCCBhe rite tonu te mahi, arā, ko te tiaki i te pūnaha hiko mai i te taumaha rawa me te poto o te ara iahiko. Heoi, e kite ana tātou, he rerekētanga kei waenganui i ngā mea e rua. He iti ake ngā MCB, he pakari ake, he iti ake te utu, engariNgā MCCBhe kaha ake, he roa ake te mau, ā, he utu nui ake. Ko te tono me ngā whakaritenga o nāianei ngā mea matua hei whakaaroaro māu ina whiriwhiri ana i waenga i ngā mea e rua.
