He aha ka nui uea no ka lawelawe 150 amp (Alakaʻi)
Nā mea
He mea nui ka ʻike ʻana i ka amperage a me ke ana uea i ka wā e hoʻonui ai, wili hou a hoʻokomo paha i kahi kaapuni hou. ʻO ka Amplitude ka waiwai kiʻekiʻe loa e hiki ai i kahi conductor ke kūpaʻa mau ma lalo o nā kūlana hana maʻamau me ka ʻole o kāna helu wela.
Hoʻoholo ʻia ka nui o ke au e hiki ai i kēlā me kēia uea uila ke lawelawe e kona mau ʻāpana, anawaena, a me ka lōʻihi kaapuni. No laila, no ke kōkua ʻana iā ʻoe i kāu uea, e kūkākūkā mākou i ka nui o ka uea no 150 amps āu e pono ai, a e hāʻawi mākou iā ʻoe i kahi pakuhi o nā nui uea no nā amplifier e kūpono i kou pae mana.
He aha ka nui amp uea e pono ai iaʻu no kahi kaapuni 150 amp?
ʻO ka nui uea i manaʻo ʻia no kahi kaapuni 150 amp he 1/0 uea keleawe. Pono ka nui uea kūpono i kēlā me kēia kau uila uila. No laila, pono e nānā i ka nui o ka uea o kāu amplifier no ka hōʻoia ʻana ua koho ʻoe i ka nui kūpono no kāu wattage.
ʻO ka nui o ka nui o ke kaula, ʻoi aku ka nui o ka mana a me nā lako e loaʻa iā ʻoe. Inā hoʻohana ʻia kahi uea liʻiliʻi ma mua o ka mea pono no ka amplifier, e hoʻohaʻahaʻa ka uea a heheʻe ka uhi. ʻO kēia ma muli o ka nui o ke au e kahe ana ma ia mea i hoʻohālikelike ʻia me ka helu mana o ke kaula.
Palapala Nui Uea
E hoʻomanaʻo mau ʻo ka hoʻokomo ʻana i nā uwea uila he mea weliweli a hiki ke hopena i ka hōʻeha a i ʻole ka pōʻino waiwai inā hana hewa. No laila, he mea nui e koho a hoʻohana i nā ana kūpono no kāu kaapuni.
No ke kōkua ʻana iā ʻoe, ua hoʻomākaukau wau i ka pakuhi nui uea amplifier ma lalo nei..

| Ka helu lawelawe | nā mea lawe keleawe | ʻO Aluminium |

| 125 Amperes | Ke keleawe #2 AWG | # 1/0 AWG |

Nīnau pinepineʻia
Aia ka palena o ke au i hiki i ka uwea ke lawe?
Wahi a ka National Electrical Code, ʻo kēlā me kēia nui uea, ʻike ʻia hoʻi ʻo ka uea gauge (AWG), he palena i ka huina o kēia manawa e hiki ke lawelawe ma mua o ka pōʻino. He mea nui e koho i ka nui uea kūpono e pale i ka overheating. ʻO ka helu o nā ʻōnaehana i hoʻopili ʻia i ke kaapuni e hoʻoholo i ka nui o ke au e hele ana ma ka uea.
ʻEhia nā amps e huki ai ka hale maʻamau?
Pono ka hapa nui o nā hale noho i kahi lako mana 100 amp. Ho'ākāka pū ka National Electrical Code i kēia me ka liʻiliʻi o ka panel amperage (NEC). Pono e lawa ka pā uila 100 amp i ka mana o ka hale hale me ka nui o nā mea hana 240-volt a me nā ʻōnaehana ea. (1)
