Ehia ka nui o ka uwea e waiho ai i ke kumu?
Nā mea
Ma kēia ʻatikala, e haʻi wau iā ʻoe i ka nui o nā uea e waiho i ka puka.
ʻO ka nui o nā uea i loko o ka puka e hiki ai ke hoʻomāhana i nā uea, a hiki ke hopena i ke ahi. Hiki i nā uea pōkole ke wāwahi i kēia mau uea. Aia kekahi kumu gula no kēia mau mea a pau? ʻAe, hiki iā ʻoe ke pale i nā kūlana i luna ma ka hana ʻana e like me ke code NEC. Inā ʻaʻole ʻoe kamaʻāina, e aʻo hou aku au iā ʻoe ma lalo nei.
Ma keʻano laulā, pono ʻoe e waiho ma kahi o 6 iniha o ka uea ma ka pahu hui. Aia ka uwea ma ka laina paepae, pono ia e puka i 3 iniha mai loko mai o ka lua a me 3 iniha i loko o ka pahu.
E hele au i nā kikoʻī hou aku ma lalo nei.
ʻO ka lōʻihi kūpono o ka uea e waiho i ka puka
He mea koʻikoʻi ka lōʻihi pololei o ka uea uila i ka palekana o nā uea.
No ka laʻana, hiki ke haki nā uea pōkole ma muli o ke kikoo ʻana. Inā loaʻa ka puka puka ma kahi me nā wela maikaʻi ʻole, pilikia paha nā uea pōkole iā ʻoe. No laila, e noʻonoʻo i kēia mau mea a pau ma mua o ke kau ʻana i ka puka uila.
NEC code no ka uwea lohi i ka pahu
Wahi a ka NEC, pono ʻoe e waiho ma kahi o 6 iniha o ka uea.
Aia kēia waiwai i kekahi kumu; hohonu pahu puka. ʻO ka hapa nui o nā puka waho he 3 a 3.5 iniha ka hohonu. No laila ʻo ka waiho ʻana ma kahi liʻiliʻi 6 iniha ka koho maikaʻi loa. Hāʻawi kēia iā ʻoe i 3 iniha mai ka wehe ʻana i ka pahu. ʻO ke koena 3 iniha i loko o ka pahu, me ka manaʻo e waiho ʻoe i ka huina o 6 iniha.
Eia naʻe, ʻo ka waiho ʻana i 6-8 iniha o ka lōʻihi o ka uea ka mea maʻalahi loa inā ʻoe e hoʻohana ana i kahi puka hohonu. E waiho i 8" no kahi pahu puka hohonu 4".
E hoʻomanaʻo e pili ana i: I ka hoʻohana ʻana i nā kumu metala, e hoʻopaʻa pono i ke kumu. No ka hana ʻana i kēia, e hoʻohana i ka uea ʻōmaʻomaʻo insulated a i ʻole ka uea keleawe ʻole.
ʻEhia ka nui o ka uea ʻē aʻe e hiki iaʻu ke waiho i loko o kaʻu panel uila?
ʻAʻole manaʻo maikaʻi ʻole ka waiho ʻana i ka uea keu i loko o ka pā uila no ka wā e hiki mai ana. Akā, pehea ka nui?
E waiho i ka uwea hou a kau ma ka lihi o ka panel.
ʻO ka waiho ʻana i nā uea he nui i loko o ka panel hiki ke hoʻomāhana. Hoʻopili wale ʻia kēia pilikia overheating me nā uwea lawe mau i kēia manawa. Nui nā uwea pōʻino ʻole i loko o ka pā uila nui, e like me nā uwea honua. No laila, ʻae ʻia ʻoe e haʻalele i ka nui o nā uea honua, akā ʻaʻole e waiho i ka nui. E hōʻino kēia i kāu pā uila.
Aia nā code no kēia mau nīnau. Hiki iā ʻoe ke loaʻa iā lākou ma nā code NEC aʻe.

E hoʻomanaʻo e pili ana i: Hiki iā ʻoe ke hoʻopili mau i nā uwea ke koi ʻia ka lōʻihi.
Nā Manaʻo Palekana Uila
ʻAʻole hiki iā mākou ke haʻalele i nā pilikia palekana o nā pahu uila a me nā uea. No laila, eia kekahi mau ʻōlelo aʻoaʻo palekana.
Uea pōkole loa
Hiki i nā uwea pōkole ke haki a hoʻopilikia paha i ka pilina uila. No laila, e hahai i ka lōʻihi kūpono.
E mālama i nā uwea i loko o ka pahu
Pono nā pilina uea a pau i loko o ka pahu uila. Hiki i nā uea ʻole ke hāʻawi i kekahi i ka uila.
Nā pahu uila honua
I ka hoʻohana ʻana i nā pahu uila metala, e hoʻopaʻa pono iā lākou me ka uea keleawe ʻole. Hiki i nā uwea i hōʻike ʻole ʻia ke hoʻoili i ka uila i kahi pahu metala.
Nui loa nā uea
Mai kau i nā uwea he nui i loko o kahi pahu hui. Hiki i nā uwea ke wela koke. No laila, hiki i ka wela ke alakaʻi i ke ahi uila.
E hoʻohana i nā nati uea
E hoʻohana i nā nati uwea no nā hoʻopili uea uila a pau i loko o ka pahu uila. ʻO kēia kaʻina hana kahi mālama maikaʻi loa. Eia kekahi, e pale i nā kaula uea i ka nui.
E hoʻomanaʻo e pili ana i: I ka hana ʻana me ka uila, e mālama pono i ka mālama ʻana iā ʻoe iho a me kou ʻohana. (1)
