Pūwhakaweto Ara Iahiko Iti (MCB) CJM2-125
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 i roto i te whare me ngā tāutanga rite
- He tino teitei te ōwehenga utu-kounga

Te Mātāpono Mahi o te MCB
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.
