Pehea ka manoanoa o ka uwea anana 18?
He mea nui e ʻike i ke ana o kāu uea uila. ʻO ka hoʻohana ʻana i ka uea nui hewa e hoʻolako i ke au uila hiki ke pilikia. Loaʻa ka helu 18 gauge uea i kēia manawa o 10-16 amps. Hoʻohana ʻia ia i nā kaapuni haʻahaʻa haʻahaʻa e like me nā kukui kukui - 10 amperes.
Pehea e ʻike ai i ka mānoanoa o ka uwea anana 18? Hiki iā ʻoe ke nānā i ka helu ampere a i ʻole ka mānoanoa ampere maoli i hōʻike ʻia ma ka uhi insulation. He 18 iniha ka manoanoa o na uea ana 0.048. Hiki ke hoʻololi i kēia i 1.024 mm. A ʻo ka helu kiʻekiʻe loa o nā watts i hiki i nā uea ana 18 ke lawelawe ʻo 600 watts. Hiki iā ʻoe ke hoʻohana i ka NEC Wire Thickness Calculator e helu i ka mānoanoa uea 18 ana.
Ma kēia alakaʻi, e hāʻawi mākou i nā papa a me nā pakuhi e kōkua iā ʻoe e nānā i ka mānoanoa uea. E wehewehe a hōʻike pū mākou i ka helu mānoanoa uea.
Uea mānoanoa 18 ana
E like me kaʻu i ʻōlelo ai, 18 mau uea ana he 1.024 mm (0.048 iniha) mānoanoa. Loaʻa iā lākou ka helu o kēia manawa o 16 amps. Eia naʻe, pili pū ka lōʻihi o ke kaula i ka helu ampere. Hiki i nā uea ana 18 ke mālama i 16 amps no ka uea 12 ". He mea nui e hoʻomaopopo i ka hoʻohana ʻana i nā uea nui e hoʻonui i ka hiki i kēia manawa. ʻO kēia ma muli o ka hoʻololi ʻana o ke ana o ka uea e like me ka mānoanoa.
Manaʻo wau e hoʻohana ʻoe i ka uwea nui aʻe i nā mea hoʻomālamalama a me nā kaapuni uila ʻē aʻe i kou home. Hāʻawi nā uea ana nui i ka uwea hale kūpono no ka mea hiki iā lākou ke mālama i nā helu amperage kiʻekiʻe. Hiki i nā uwea liʻiliʻi ke wela a ma kēia hihia ke alakaʻi i ka uila.
ʻO ka nui o nā watts i hiki i nā uea anana 18 ke lawelawe ʻo 600 watts (i kapa ʻia ʻo wattage - ka nui o kēia manawa e hiki ai i kahi uea ana ke lawe). Hōʻike ʻia nā helu Amperage no 18 ana a me nā uea ana ʻē aʻe ma ka papa ma lalo.
Papa mānoanoa uea
Ma ka ʻōnaehana AWG - American Wire Gauge, ua helu ʻia nā ana a me nā anawaena o ke ana uea e ke kumu:
Mai ke kumu, hiki iā mākou ke hoʻoholo no kēlā me kēia ʻeono anana e pāpālua ke anawaena uwea. A no kēlā me kēia ʻekolu calibers, pāpālua pū ka ʻāpana cross-sectional (CA). Hōʻike ʻia ke ana uea Metric AWG ma ka papa ma lalo.
Helu Uea Manoanoa
E wehe no ka mea, Helu mānoanoa uea.
Na ka mea helu mānoanoa uea e kōkua iā ʻoe e helu i ka mānoanoa uea. ʻO nā mea a pau āu e hana ai, ʻo ia ke komo i nā waiwai a koho i ke ʻano o ka uea - no ka laʻana, keleawe a alumini paha. Hāʻawi ka helu mānoanoa uea iā ʻoe i nā hopena pololei e kōkua iā ʻoe e hoʻoponopono i nā pilikia pili i ka helu ʻana i ka mānoanoa uea. (1)
Nā hiʻohiʻona helu helu Uea
- Puna uila - ma aneʻi hiki iā ʻoe ke koho i ka volta kumu - 120, 240 a me 480 volts.
- Ka helu o nā pae - maʻamau maʻamau hoʻokahi a i ʻole ʻekolu manawa. Pono nā kaʻa kaʻa kaʻa hoʻokahi i 3 mau alakaʻi, a ʻo nā kaʻa kaʻa ʻekolu e koi i 3 mau alakaʻi. Hoʻoholo ʻo NEC i ka mānoanoa o nā conductors.
- Amps - Hāʻawi ʻia ka manawa i huki ʻia mai ka ukana e ka mea hana mea hana. ʻO kekahi o nā koi o ka NEC no nā kaʻa kaʻa hoʻokahi, ʻo ke ʻano he 1.25 mau manawa o ka ukana.
- Volta ʻae ʻia hāʻule, AED - hiki iā ʻoe ke hoʻokomo i ka AVD i ka helu helu a loaʻa ka mānoanoa uea 18 anana.
Pākuʻi: Pono ʻoe e hahai i nā kuhikuhi NEC i ka wā e hoʻohana ai i ka calculator e loaʻa ai nā hopena maikaʻi.
E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
- ʻO wai ka uea mai ka pākaukau a i ka mea hoʻomaka
- He aha ka nui uea no 30 amps 200 kapuai
- He aha ka nui o ka uwea no ka umu uila
