He aha te MCB?
Ko te Kaiwhati Arahiko Iti (MCB) he momo ara iahiko he iti te rahi.Ka tapatapahia tonutia te ara iahiko hiko i nga ahuatanga kino i roto i nga punaha tuku hiko, penei i te utu nui, te iahiko poto ranei.Ahakoa ka taea e te kaiwhakamahi te tautuhi ano i te MCB, ka kitea pea e te whaa enei ahuatanga, a me whakakapi e te kaiwhakamahi.
Ko te MCB he taputapu hiko e whakamarumaru ana i nga waea hiko me nga uta mai i te kohu o te ia, hei aukati i te ahi me etahi atu tupono hiko.He pai ake te whakahaere a MCB, ka tere te whakaora i te mana.Mo te taumahatanga me te whakamarumaru ara iahiko i roto i nga tono noho, ko te MCB te mea tino rongonui.He tino tere nga MCB ki te tautuhi, kaore e hiahiatia he tiaki.Ka whakamahia te whakaaro taapiri-rua i roto i nga MCB hei whakamarumaru mai i te waipuke me te iaia iahiko poto.
