Ngā Mahanga Whaihua hei Ārai mā ngā Momo Pūwhakawhiti Ara Iahiko Katoa: Āta karohia ngā Hapa e 5 a te Kaimahi Hiko hei Whakamahere i te Haumaru o te Whakamahinga Hiko

I te marama kua taha ake nei, i hē tetahi kaimahi hiko i tētahi wheketere hanga i tētahi hapa iti noa iho i a ia e pupuri ana i tētahi kaiwawao hiko toenga (RCCB): i hurihia e ia te hononga waea whenua me te kore e tirotiro anō. I roto i te haora kotahi, i puta he hapa turuturu i roto i te awheawhe, engari kāore i taea te pakaru o te RCCB, ka pā he ru hiko ki tētahi kaimahi, ā, ka kati te wheketere mō te tiaki. Kāore tēnei i te rerekētanga—neke atu i te 60% o ngā pakaru o ngā kaiwawao hiko nā ngā mahi hē, e kore e whakanui noa i ngā utu tiaki engari he tūponotanga haumaru nui hoki. I tēnei rā, ka wehewehea e mātou ngā hapa e 5 e mahia ana e ngā kaimahi hiko i te wā e mahi ana me ngā momo kaiwawao hiko katoa, hei āwhina i a koe ki te karo i ngā hapa me te whakarite kia haumaru te whakamahi hiko.

Ko te tūponotanga matua o te mahi hē kei roto i tōna ngaro me tōna whakangaromanga. He maha ngā hapa iti, pērā i te koretake o ngā hononga pūrua, ngā whakarerekētanga tawhā matapōkere rānei, kāore pea e puta he pakaru tonu engari ka pōturi haere te mahi a te kaiwawao hiko, ka arahi ki te taumaha rawa, te poto o te hiko, te turuturu rānei i roto i te wā. He rerekē ngā hanganga me ngā mahi a ngā momo kaiwawao hiko rerekē (Ngā Kaiwawao Hiko Ā-Hau - ACB, Ngā Kaiwawao Hiko Molded Case - MCCB, Ngā Kaiwawao Hiko Iti - MCB, Ngā Kaiwawao Hiko Iahiko Toenga - RCCB, Kaiwawao Iahiko Toenga me te Tiakitanga Iahiko Nui - RCBO), nō reira he rerekē anō ngā tūponotanga me ngā tikanga karo i ngā mahi hē.

Anei ngā mahi hē e rima e mahia ana e ngā tohunga hiko me ngā momo whati ara iahiko katoa, me ngā tohutohu ngaio hei karo i ēnei:

Hapa1(ACB): Katia ā-ringa matapo noa, me te kore e tapahia te kawenga, ka arahi ki te wera o te pa, te ara iahiko poto, tae atu ki te whara o te pewa.Aratohu:Whāia te tikanga kati tika mō te ACB i ngā āhuatanga kawenga nui—tapahia te kawenga i te tuatahi, tirohia te ara iahiko mō ngā hapa, kātahi ka kati i te pana kia kore ai e mahi tika i raro i te kawenga.

Hapa2(MCCB):Te whakatuwheratanga me te kati ā-ringa pinepine, ka pakaru te pūnaha mahi, ka iti ake te kaha pakaru, ā, ka poto ake te ora mahi.Aratohu:Whakamāramahia te auau tika o te whakatuwheratanga me te kati i te MCCB—kāore e tika kia whakamahia ngā mahi ā-ringa maha mēnā kāore e tika, ā, me whakahaere kia rite ki ngā tohutohu taputapu.

Hapa3(MCB):Te whakakapi matapōkere i te MCB ki tētahi iahiko teitei ake te whakatauranga, ka kore e aro te tiaki me te paunga o ngā taputapu nā te kore e piko i te wā e uta nui ana.Aratohu:Tīpakohia te iahiko whakatauranga MCB e ai ki te kawenga tuturu—kaua rawa e whakakapia ki tētahi whakatakotoranga nui ake i te mea noa, nā te mea ka ngaro te mahi tiaki taumaha.

Hapa 4 (RCCB/RCBO):

I. Ngā Mahi Hē Noa

Ngā Hapa Whānui:

1. Te hononga whakamuri/hē o ngā waea kūpapa me ngā waea ora, ka pakaru te ara iahiko kimi iahiko toenga;

2. Te korenga e mahi i ngā whakamātautau iahiko toenga whakatauira mā te pātene whakamātautau mō te wā roa, ka arahi ki te kore e kitea te whakakorenga o ngā mahi tiaki;

3. Te whakapoto i te ara iahiko o te waeine tiaki iahiko toenga kia kore ai e taea te tiaki matua.

Ngā Hapa Motuhake mō te RCCB:

1. Whakamahinga motuhake mō te tiaki i te taumaha rawa/te ara iahiko poto (kāore he mahi tiaki i te au nui o ngā RCCB);

2. He hē te raupapatanga o te whakairinga ina honoa ki ngā whati ara iahiko (te tāuta i te RCCB i mua i te whati ara iahiko).

Ngā Hapa Motuhake mō te RCBO:

1. Kōwhiria mā ngā tawhā iahiko toenga anake, me te kore e aro ki te taurite o te iahiko whakatauranga o ngā kawenga, ka puta ai te hinganga o te iahiko nui;

2. Te whakamahi noa iho hei taputapu tiaki iahiko toenga parakore, ā, kāore e whakamahia tana mahi tiaki iahiko nui kua whakauruhia, ka hua ake he taurite o te ara iahiko mai i te hononga o ngā kaiwawao ara iahiko taurite.
