Ke Hoʻomaopopo nei i ke Koʻikoʻi oMcba meRcboma ka Palekana Uila

I ke ao hou o kēia au, hilinaʻi nui mākou i ka uila no aneane nā ʻano āpau o ko mākou ola. Mai ka hoʻoikaika ʻana i ko mākou mau home a me nā ʻoihana a hiki i ka hoʻoikaika ʻana i nā mīkini ʻoihana, ʻaʻole hiki ke hoʻonui ʻia ko mākou hilinaʻi ʻana i ka uila. No kēia hopena, pono mākou e kau mua i ka palekana o ka mana, pale i nā ulia pōpilikia, a hōʻoia i ka holo pono ʻana o ka ʻōnaehana mana. ʻElua mau ʻāpana koʻikoʻi e pāʻani ana i kahi kuleana koʻikoʻi i ka palekana uila ʻo ia ka Miniature Circuit Breaker (MCB) a me kaMea Hoʻopau Kaapuni Au Koena me ka Palekana Overcurrent (RCBO)Ma kēia blog, e luʻu mākou i loko o ke koʻikoʻi o Mcb a me Rcbo i ka hōʻoia ʻana i ka palekana uila.

ʻO ka mea mua, e hoʻomaopopo kākou i ke ʻano o MCB a me RCBO a me kā lākou mau hana. He mau kuapo uila ʻakomi nā MCB i hoʻolālā ʻia e pale i nā kaapuni mai ka pōʻino i hana ʻia e ka overload a i ʻole ka pōkole. Hana lākou ma ka ʻike ʻana i nā hewa i loko o nā ʻōnaehana uila a me ke kāpae ʻana i ke kahe o ka uila e pale aku i kekahi pōʻino hiki. ʻO RCBO, ma ka ʻaoʻao ʻē aʻe, he hui pū ʻana o RCD (Residual Current Device) a me MCB e hāʻawi ana i ka hewa honua, ka overload a me ka pale kaapuni pōkole. He mea nui loa nā RCBO i ka hāʻawi ʻana i ka pale mai ka haʻalulu uila a me ka uila.

ʻO kekahi o nā kumu nui he mea nui nā MCB a me nā RCBO i ka palekana uila ʻo ko lākou hiki ke pale i nā pōpilikia uila. ʻO nā ukana nui a me nā kaapuni pōkole e hōʻike ana i nā pilikia nui o ke ahi a me ka hōʻino ʻana i nā lako uila. Ua hoʻolālā ʻia nā MCB e hoʻopau koke i ke kahe o ka uila ke ʻike ʻia kahi ukana nui a i ʻole kaapuni pōkole, no laila e pale ana i ka hiki ke hōʻino ʻia ke ahi a me ka ʻōnaehana uila. Pēlā nō, hāʻawi nā RCBO i ka palekana hou aʻe ma ka wehe ʻana i ke kaapuni i ka hanana o kahi hewa o ke au i koe, no laila e hōʻemi nui ana i ka pilikia o ka haʻalulu a me ka uila.

Eia kekahi, he kuleana koʻikoʻi ko MCB a me RCBO i ka pale ʻana i nā lako uila a me nā mīkini. Ke loaʻa kahi hewa, e hoʻokaʻawale koke ʻo MCB a me RCBO i ke kaapuni hewa e pale aku i ka hōʻino ʻana i nā mea uila a me nā lako. ʻAʻole wale kēia e hōʻoia i ke ola lawelawe o nā lako, akā e hōʻemi pū kekahi i ka pilikia o ka pohō waiwai ma muli o ka hōʻino ʻia o nā lako.

Ma waho aʻe o ka pale ʻana i nā pōʻino uila a me ka hōʻino ʻana o nā lako, hāʻawi nā MCB a me nā RCBO i ke kūpaʻa holoʻokoʻa a me ka hilinaʻi o nā ʻōnaehana uila. Ma ka hoʻokaʻawale ʻana i nā kaapuni hewa a me ka pale ʻana i nā overloads, kōkua kēia mau mea hana i ka mālama ʻana i ka mana mau i ke koena o ka ʻōnaehana. He mea nui loa kēia i nā wahi ʻoihana a me nā ʻoihana kalepa, no ka mea, ʻo kekahi hoʻopilikia ʻana i nā ʻōnaehana uila hiki ke hopena i ka downtime nui a me nā pohō kālā.

I ka hōʻuluʻulu ʻana, ʻo ka mea haki kaapuni liʻiliʻi (MCB) a me ka mea haki kaapuni o ke au koena (RCBO) me ka hana pale overcurrent he mau ʻāpana pono ʻole ia e hōʻoia i ka palekana o ka uila. ʻO ko lākou hiki ke pale i nā pōpilikia uila, pale i nā lako a mālama i ke kūpaʻa o ka ʻōnaehana uila e lilo ai lākou i mea koʻikoʻi ma nā wahi noho a me nā wahi kalepa. Ma ka hoʻonohonoho mua ʻana i ke kau ʻana a me ka mālama ʻana i nā MCB a me nā RCBO, hiki iā mākou ke hōʻemi nui i ka pilikia o nā ulia uila a hōʻoia i ka hana palekana a me ka pono o nā ʻōnaehana uila.
