Pehea ka manoanoa o ka uwea anana 12?

ʻO ke ana uwea kahi ana o ke anawaena o nā uea uila. ʻO 12 gauge uea ka uea koho waena no ka hoʻoili ʻana i kēia manawa. Hiki i nā uea ana 12 ke lawe i 20 amps. ʻO ka ʻoi aku o ka lako o kēia manawa i ka uea e lilo ia i mea hiki ʻole ke hoʻohana.

Ma kēia alakaʻi, e hele mākou i nā kikoʻī hou aku e pili ana i ka mānoanoa o 12 gauge uea a me kona mau ʻano.

Ma hea e hiki ai iaʻu ke hoʻohana i ka uwea anana 12? Hoʻohana ʻia ia i loko o nā lumi kuke, nā lumi ʻauʻau a me nā ipu waho. Hiki ke hoʻohana i ka ea 120 volt e kākoʻo ana i 20 amps ke hoʻohana i 12 gauge uea.

ʻO ke anawaena uwea 12 he 2.05 mm a i ʻole 0.1040 in. SWG metric. He haʻahaʻa ko lākou kūpaʻa i ka kahe o kēia manawa a hiki ke mālama i ka 20 amps.

He aha ka uwea anana 12?

E like me ka mea i ʻōlelo ʻia ma luna, ʻo 12 gauge wire he 2.05 mm (0.1040 in.) ma SWG metric. He haʻahaʻa loa ko lākou kūpaʻa, e hoʻolilo iā lākou i mau conductors kūpono no ka hoʻouna ʻana i ke au uila.

Hoʻohana ʻia lākou i loko o ka lumi kuke, nā ipu waho, nā halepaku, a me nā ea ea 120 volt (20 amp). E like me ke kānāwai, hiki ke hoʻopili ʻia nā uea lahilahi ʻoi aku ma mua o nā uea mānoanoa.

ʻO nā uea 12 gauge nā mea hoʻouna mana maikaʻi, ʻoi aku ka nui ma kahi e pono ai kahi lako mana nui. No laila, manaʻo wau e hoʻohana i ka uea gauge 12 no ka hoʻololi mana ʻoi aku ka maikaʻi.

ʻO ke kumu, ʻaʻole pili nui ka maikaʻi o ka uea i ka nui o ka uea. Eia nō naʻe, me ka uea 12 ana (nā anana liʻiliʻi), hiki ke loaʻa i nā uea uila conductive. He haʻahaʻa nō hoʻi ko lākou kūʻē ʻana, ʻoi aku ka liʻiliʻi ma mua o 5% o ka nui o ke kūpaʻa. Hiki iā ʻoe ke lilo i 1.588 ohms no 1000 kapuaʻi o 12 ana uea keleawe. Hiki iā ʻoe ke hoʻohana i 12 gauge flexible wire me kahi leo 4.000 ohm. Manaʻo wau e hoʻohana i 12 gauge copper wire ma kahi o 12 gauge alumina. ʻOi aku ka ʻoi aku o ka ʻoi aku o ke koʻikoʻi o nā uea alumini.

Ua helu ʻia i kēia manawa no nā uea ana 12

ʻO ka helu kiʻekiʻe loa o nā amps i hiki ke mālama i ka uea 12 anana he 20 amps. A hiki ke lawe ʻia he 20 amps i 400 kapuaʻi ma 12-gauge insulated uea keleawe. Inā ʻoi aku ka lōʻihi o ka uwea ma mua o 400 kapuaʻi, e hoʻomaka ana ka nalo uila. ʻO ka hoʻonui ʻana i ka uila e hoʻonā i ka pilikia. Hiki i ka uea nui ke lawe i ke au ma kahi lōʻihi ma mua o ka uea liʻiliʻi.

I ka hoʻomaʻamaʻa, 12 mau uwea ana, ʻoiai ua helu ʻia no 20 amps, hiki ke hoʻopaʻa i 25 amps. Eia naʻe, e hoʻomanaʻo e hiki i nā helu ampere kiʻekiʻe ke puhi i kāu mau uea a me ka mea hoʻomaha kaapuni. He mea pono e hoʻomaopopo i ka kiʻekiʻe o ka wela wela, ʻoi aku ka kiʻekiʻe o ka ampere. Ma kēia ʻano, ʻoi aku ka haʻahaʻa o nā uea alumini ma mua o nā uea keleawe; no laila e lawe lākou i nā amp haʻahaʻa i hoʻohālikelike ʻia me nā uea keleawe i ka piʻi ʻana o ka helu wela. (1)

Uea mānoanoa 12 ana

E like me ka mea i ʻōlelo ʻia ma mua, ʻo 12 gauge wire he 2.05mm (diameter). Pili ka ana a me ka mānoanoa uwea. ʻOi aku ka ʻoi aku o ke kūpaʻa o kēia manawa i nā mea ʻike lahilahi. Ma muli o ka hilinaʻi ʻole ʻana o ka volta i kēia manawa, ʻo ka emi ʻana o ka manawa i nā uea lahilahi e hoʻonui ai i ka hiki ke hiki i ka uwea. ʻO ka wehewehe kikoʻī no kēia haʻalele ʻana, ʻo nā uea lahilahi he haʻahaʻa haʻahaʻa haʻahaʻa. ʻO nā electrons nā mea lawe i ka conductivity uila. ʻO nā uea mānoanoa he ʻoi aku ka nui o ka hoʻopaʻa electron.

E nānā i kekahi o kā mākou ʻatikala ma lalo nei.

• Pehea ka manoanoa o ka uwea anana 18
• ʻO wai ka uea mai ka pākaukau a i ka mea hoʻomaka
• Hiki paha ke hoʻohui i nā uwea ʻulaʻula a me ka ʻeleʻele
