Kodi kukula kwa waya kwa 30 amps 300 mapazi ndi chiyani?

Kugwiritsa ntchito mawaya amagetsi oyenera pamabwalo ndikofunikira kuti mupewe ngozi komanso kupewa moto. Izi ndichifukwa choti mphamvu ikaperekedwa pamtunda wautali kudzera pamawaya amkuwa kapena aluminiyamu, madontho amagetsi amatha kuchitika. Chifukwa chake, kuti muwonetsetse chitetezo, muyenera kugwiritsa ntchito waya wolondola pa unyolo wanu wa mapazi 300.

Dikirani ndikukuwonetsani kuwerengera ndikukuphunzitsani kukula kwa ma chingwe kuti mugwiritse ntchito mtsogolo:

Mukufuna waya wochuluka bwanji pa ma amps 30? (80% NEC kodi)

Muyenera kugwiritsa ntchito waya womwe ungagwire osachepera 37.5 amps. Chifukwa chake #8 AWG waya yomwe imatha kunyamula ma amps 50 ndiye waya woyenera pa waya wanthambi iyi.

Nthawi zambiri ndimagwiritsa ntchito chowerengera chotsitsa ma voltage kapena njira ya National Electrical Code (NEC) pamlingo wovomerezeka wa 30 amp wire gauge.

**Pa dera la 30-amp, simungagwiritse ntchito waya wamagetsi wa 30A.

Simufunikanso kugwiritsa ntchito waya # 10 AWG 35A. Izi zili choncho chifukwa waya wochuluka wa waya wozungulira nthambi iliyonse ndi 80% ya mlingo waposachedwa pa katundu uliwonse. (NEC 220-2)

Ubwino umachitcha kuti NEC voltage drop calculator yokhala ndi 80% mphamvu. Izi zikuwonetsa kuti ma amp 30 awa akuyenera kuyimira zosaposa 80% ya kuchuluka kwa waya (waya wamkuwa kapena aluminiyamu).

Umu ndi momwe mungadziwire kuchuluka kwa waya wa mphamvu yomwe mukufuna pagawo lamagetsi la 30 amp:

Poganizira zofunikira za 80% NEC, ndikukhulupirira kuti 35A #10 AWG ndiyosakwanira. Ndilikulu mokwanira ndi 35A, koma osati ndithu.

Timafunikira chingwe chomwe chimatha kugwira ma amps 37.5 kuti tigwiritse ntchito 30 amp switch. Kukula kotsatira #10 AWG (35A) ndi kukula kwa waya #8 AWG (50A).

Chifukwa chake, kukula kwa waya koyenera kwa 30 amp circuit breaker ndi #8 AWG waya, yomwe ili ndi ma 50 amps.

Kodi kukula kwa waya kwa 30ft 300 amp subpanel ndi chiyani?

Mudzafunika waya womwe ungathe kugwira ma amps osachepera 60.

Chifukwa chake kugwiritsa ntchito #6 AWG waya yomwe imatha kugwira 65A ndiye waya wabwino kwambiri kwa inu.

Ndikuphunzitsani momwe ndinawerengera pansipa.

Kutsika kwamagetsi kumachitika pamene magetsi amaperekedwa pa waya wamkuwa wa 30 amp kapena waya wa 30 amp aluminiyamu patali. Kutsika kwamagetsi kumasungidwa osakwana 3% pamtunda wochepera 10 mapazi, kotero simukuyenera kuziganizira. (1)

Mwachitsanzo, muyenera kuwerengera kutsika kwamagetsi pa 50, 100, 200, kapena 300 mapazi. Kuphatikiza apo, mumasinthira izi powonjezera mphamvu zamakono. Koma zingati?

Malinga ndi NEC 310-16, zapano ziyenera kuchulukitsidwa ndi 20% pamamita 100 aliwonse kuchokera pagawo lowonjezera la 30 amp.

Mwachidule, izi zikutanthauza kuti muyenera:

• Onjezani zamakono ndi 10% pawaya wa 30 amp 50 mapazi kuchokera pazowonjezera.
• Onjezani amperage ndi 20% pazingwe 30 amp gauge mapazi 100 kuchokera pagawo laling'ono.
• Onjezani zamakono ndi 40% pawaya wa 30 amp 200 mapazi kuchokera pazowonjezera.
• Pomaliza, onjezani amperage ndi 60% kwa waya wa 30 amp 300 mapazi kuchokera pazowonjezera.

Zotsatirazi zikuwonetsa momwe mungadziwire mphamvu ya 30 amps patali:

Tiyerekeze kuti mukufuna subpanel 300 mapazi kuchokera 30 amp mains.

Tikudziwa kale kuti osachepera 0 amps amakono amafunikira pa mapazi a 37.5. Kuti mufotokoze zowonjezera 300 mapazi kuchokera pazitsulo zowonjezera, muyenera kuonjezera panopa ndi 20% pa mtunda uliwonse wa 100. Chifukwa chake muyenera kukulitsa amperage ndi 60% kuti mupeze zokwanira mapazi 300 a dera lanu.

Choncho, mukufunikira mzere wokhoza kunyamula ma amps 60 pa 30 amp circuit pa 300 mapazi. Tsoka ilo, #8 AWG waya pano ndi 50A yokha.

Zikatero, sankhani #6 AWG waya ndi 65A.

Onani zina mwazolemba zathu pansipa.

• Waya wanji wa 30 amps 200 mapazi
• Ndi kukula kotani kwa waya wa 150 amps?
• Komwe mungapeze waya wandiweyani wamkuwa wa zidutswa
