Pūwhakaweto Ara Iahiko Iti (MCB) CJM7-125
Te Hanganga me te Āhuatanga
- Te kaha poto-poto teitei 10KA.
- I hangaia hei tiaki i te ara iahiko e kawe ana i te iahiko nui tae atu ki te 125A.
- Tohu tūranga whakapā.
- Whakamahia hei pana matua mō te whare me ngā tāutanga ōrite.
- He iti te whakapaunga pūngao, he nui hoki te penapena pūngao
- Whakapai ake i te taiao whakaputa me te taiao ā-taiao, me te penapena i te tiaki taputapu
- Te tiaki i te taumaha nui
- Katia wawe
- Te kaha pakaru teitei
Haumaru, Pono hoki
- Katia aunoa me te iti o te mura hiko mō te roa o te ora mahi o ngā taputapu
- Teitei tiaki: IP20—Hei whakapūmau i tētahi hononga haumaru, pono hoki
- Ātete ki te paru: Taumata 3—Hei ārai i te puehu me te parahanga kawe hiko

He aha te MCB?
Pūwhakapakari Arahiko ItiKo te MCB he momo whati hiko he iti te rahi. Ka tapahia tonutia te hiko i roto i ngā āhuatanga kino o ngā pūnaha tuku hiko, pērā i te utu nui rawa, te iahiko poto rānei. Ahakoa ka taea e te kaiwhakamahi te tautuhi anō i te MCB, ka kitea pea ēnei āhuatanga e te fiusi, ā, me whakakapi e te kaiwhakamahi.
Ina pāngia te MCB e te au nui tonu, ka wera te rīpene whakarewa rua, ka piko. Ka tukuna he raka hiko ina hurihia e te MCB te rīpene whakarewa rua. Ina hono te kaiwhakamahi i tēnei here hiko ki te tikanga mahi, ka whakatuwherahia ngā hononga pakaru ara iahiko iti. Nō reira, ka meinga te MCB kia whakaweto, kia whakamutua hoki te rere o te iahiko. Me whakakā takitahi te kaiwhakamahi i te MCB kia whakahokia mai ai te rere o te iahiko. Ka tiaki tēnei taputapu i ngā hapa i puta mai i te au nui rawa, te taumaha rawa, me ngā ara iahiko poto.
