Ngā whakatūpato i te wā e whakamahi ana i te RCBO

He mea nui te parenga hiko toenga (RCBO) me te mahi tiaki iahiko nui hei whakarite i te haumaru o ngā pūnaha hiko iti, ngā taputapu rānei. Ehara i te mea ka taea anake te ārai i ngā aituā ru hiko me te tiaki i te haumaru whaiaro, engari ka taea hoki te aroturuki i te āhua o te whakamahana whenua. Heoi, he mea nui kia mārama ko te tāutanga o te RCBO kāore e kī taurangi i te haumaru. Me arotahi tātou ki te ārai me te whakatinana i ngā mahi hangarau haumaru hei whakatutuki i te whakamahinga hiko haumaru. He tiaki tāpiri noa te RCBO i roto i ngā mahi tiaki taketake. Ko te whakahaere tupato me te whakatairanga me te whakaakoranga mō te whakamahinga hiko haumaru te taurangi matua o te haumaru.

Kotahi te mea hei maumahara māu i te whakamahi i te RCBO, ko te mea ka taea anake te tiaki i te tinana tangata mēnā ka pā mai he aituā hiko kotahi-wāhanga. Mēnā ka āraia te tinana tangata i te whenua, ā, ka pā atu ki ngā raina ā-wāhanga e rua, ki te raina ā-wāhanga kotahi rānei me te raina kūpapa kotahi, e kore te RCBO e mahi. Ko te tikanga tēnei e kore e tiakina i roto i tēnei āhuatanga. Nō reira, me mōhio ngā kaiwhakamahi ki tēnei herenga, ā, me mahi i ētahi atu mahi ārai hei whakaiti i te mōrearea o aua aituā.

Ko tētahi atu whakatūpato hei whakaaroaro ko te whakamarumaru hiko i muri i te pūwāhi whakairi RCBO. He mea nui kia pai te whakamarumaru o te hiko mai i te whenua. Mena ka whakaitihia te whakamarumaru ki te whenua, ā, ka nui ake te ia turuturu i tētahi uara, tata ki te 15mA, ka mahi te RCBO ka tapahia te pūtake hiko. E whakanui ana tēnei i te hiranga o te pupuri i te whakamarumaru pai mai i te whenua hei ārai i ngā hapa me te whakarite kia tika te whakapaunga hiko. Me tirotiro me te pupuri tonu i te whakamarumaru kia kore ai e puta he tūponotanga kino.

Ina whakamahia te parenga whakarōpū o te whatunga hiko iti-ngaohiko, he mea nui kia whakamahia te RCBO whakaroa mō te parenga taumata-runga. Me roa ake te wā pakaru o te momo RCBO whakaroa i te wā mahi o te parenga taumata-raro, arā, 0.1 ki te 0.2 hēkona te nuinga. Mā tēnei mahi ārai ka whakarite kia whānui ake, kia taurite hoki te huarahi parenga i roto i te whatunga. Mā te whai i tēnei aratohu, ka taea e koe te whakaiti i ngā mōrearea me ngā tūponotanga ka pā mai, me te whakapai ake i te haumaru whānui o tō pūnaha hiko.

Hei whakarāpopototanga, ahakoa he mea nui ngā RCBO mō te tiaki i te haumaru whaiaro me te aroturuki i te whakamahana whenua i roto i ngā pūnaha hiko iti, i ngā taputapu rānei, he mea nui anō hoki kia mārama ki ō rātou herenga me te mahi i ngā mahi whakatūpato e tika ana. Me arotahi ngā kaiwhakamahi ki te aukati me te whakatinana i ngā mahi hangarau haumaru hei whakarite i te whakamahinga haumaru o te hiko. Mā te whakahaere tupato i te whakamahinga hiko, te pupuri i te whakamahana pai, me te whakatinana i ngā mahi tiaki kua whakarōpūtia ka taea e tātou te whakatutuki i te taurangi taketake o te whakamahinga hiko haumaru.
