Kodi waya wa 14/2 amagwiritsidwa ntchito bwanji (Pamanja)

Mawaya amagetsi amapezeka m'makulidwe osiyanasiyana ndi ma geji kuti agwirizane ndi kuchuluka kwa dera. Aliyense wa iwo ali ndi cholinga chapadera ndi mphamvu, ndipo ang'onoang'ono / owonda waya, amakwera nambala. Mu ntchito zamagetsi zogona, mawaya a 10-gauge ndi 12-gauge amagwiritsidwa ntchito kwambiri, ndipo m'nkhaniyi tikambirana za 14-gauge, makamaka 14/2, mwatsatanetsatane.

Ndiye tiyeni tiwone mwatsatanetsatane zomwe waya 14 amagwiritsidwa ntchito ndi zina zambiri za mphamvu yake ndi chitetezo.

Kugwiritsa ntchito waya 14/2

Kukula kwamawaya kosiyanasiyana kumayenderana ndi ntchito zosiyanasiyana mnyumba mwanu. Mwachitsanzo, waya wa 14/2 nthawi zambiri amagwiritsidwa ntchito popangira magetsi ocheperako, nyali, ndi zowunikira pamagetsi 15 amp. Uwu ndiye mphamvu yayikulu yomwe waya wa 14/2 imatha kugwira ndikupereka mphamvu zokwanira. Chifukwa chake, bola ngati yolumikizidwa ndi 15 amp circuit, mutha kuyigwiritsa ntchito mosamala ndi waya 14/2. Komabe, ngati ili pamwamba pa 15 amps, monga 20 amp circuit, waya wanu wa 14/2 sangapereke mphamvu zokwanira, zomwe zimakuikani pachiwopsezo cha kugwedezeka kwa magetsi. Pankhaniyi, muyenera kukweza ku waya wamphamvu, wokulirapo monga waya wa 12/2.

Kumvetsetsa 14/2 mawaya

Mu waya wamagetsi wa 14/2, nambala 14 imasonyeza gawo la mtanda wa woyendetsa, ndipo nambala 2 imasonyeza chiwerengero cha oyendetsa chingwe. Waya wa 14/2 ndi chingwe chamagetsi chokhala ndi ma conductor amagetsi a 14-gauge:

• Mawaya akuda ndi oyera "otentha" - amanyamula zamakono kuchokera pagulu kupita ku chinthu, chomwe chingakhale chosinthira, chotulukira, nyali kapena chipangizo. Pali mitundu ina ya mawaya otentha, ngakhale kuti imakhala yochepa kwambiri.
• Ground Wire, Green kapena Bare Copper Waya - Pakachitika vuto la pansi, waya wapansi amapereka njira yobwezera zolakwika pagawo, kutsegula chosweka kapena kuwomba fuse, ndikuzimitsa mphamvu.

Плюсы

• Izi ndizotsika mtengo kuposa mawaya a geji 12/2 ndi mawaya ena amagetsi okhuthala.
• Ndiwosinthika kwambiri, zomwe zimapangitsa kuti zikhale zosavuta kugwira nawo ntchito.

Минусы

• Waya woyezera 14/2 mudera la 15 amp amapereka mphamvu zosakwanira kuti agwiritse ntchito bwino ma AC mayunitsi, zida zamagetsi, ndi zida zina.
• Ngati mukugwiritsa ntchito 14 gauge waya ndipo mukufuna kukweza chotulukapo kukhala ma amps 20 pambuyo pake, muyenera kuthyola kaye ndikuyikanso ndi waya woyezera 12, ndiyo ntchito yambiri yolumikizira.

Chitetezo

Mawaya a 14 gauge ndi ma 15 amp circuits sangagwiritsidwe ntchito ponseponse panyumba yanu chifukwa zipangizo zina zapakhomo ndi zipangizo zamagetsi zimafuna ma amps 20 monga mawindo a air conditioners, vacuums sitolo, etc. bafa, panja ndi garaja. Chotsatira chake, mudzafunikanso kukhazikitsa 20/12 gauge waya m'malo mwa 2/14 gauge waya kuti mupereke mphamvu ndi magetsi okwanira 2 amp circuit. Omanga nyumba ambiri amagwiritsa ntchito mawaya 20 kuti alumikizane ndi mabwalo onse ndi mabwalo 12 amp.

Mafunso ofunsidwa kawirikawiri

Kodi 14/2 waya wokwanira amatha kunyamula ndi chiyani? 

Mawaya 14/2 ndi otetezeka kuti agwiritsidwe ntchito pamabwalo mpaka 15 amps. Kugwiritsa ntchito waya 14/2 pa ma amps oposa 15, monga 20 amp circuit, sikuli bwino. Choncho, kuti mukhale ndi mawaya otetezeka a magetsi, ndi bwino kusankha chingwe choyenera cha waya malinga ndi momwe zilili panopa.

Kodi ndingadziwe bwanji kulimba kwa dera langa?

Pezani ndi kutsegula bokosi losinthira kuti muwone kuchuluka kwa dera lomwe mukugwira nalo. Kenako, pezani chosinthira chomwe chimayang'anira magetsi panyumba yanu. Amperage iyenera kuwonetsedwa pa chogwirira cha switch. Kusintha kwa 15 amp kumatchedwa "15" ndipo 20 amp switch kumatchedwa "20". Madera omwe amapangira zida zazikulu zamagetsi amatha kukhala ochulukirapo.

Kodi chimachitika ndi chiyani ndikayendetsa waya wa 14/2 mudera la 20 amp? 

Waya wa geji 14 sanapangidwe kuti azinyamula magetsi ochuluka chotere. Mukakakamiza waya wa 14-gauge kuti ajambule ma amps 20 apano, amatentha kwambiri, zomwe zimapangitsa kuti kusinthaku kuyende kapena magetsi kuyatsa. Nthawi yabwino, woyendetsa dera amayenda kuti apewe kutenthedwa koopsa, koma adzataya mphamvu kudera. Zikavuta kwambiri, dera la 20 amp ndi waya wa 14 gauge lidzatentha kwambiri mpaka kuyambitsa moto wamagetsi. (1)

Ndi zitsulo zingati zomwe zingathandize 14/2 waya?

Ndi dera lanu la 15 amp lolumikizidwa ndi waya wamkuwa wa 14/2, mutha kulumikiza magetsi asanu ndi atatu. Malo ambiri amakhala ndi malo awiri, ngakhale ena ali ndi zinayi. Pogwiritsa ntchito waya wamagetsi wa 14 gauge, mutha kulumikiza zitsulo zinayi za 2-sockets kapena sockets 4-sockets ku dera limodzi la 15-amp. Komabe, ngati mukufuna kupatsa mphamvu zoposa masitepe asanu ndi atatu, lingalirani zosinthira kudera la 20 amp yokhala ndi mawaya okulirapo, monga mawaya 12.

Kodi Romex 14/2 angagwiritsidwe ntchito kuyika ma waya?

Chingwe chamagetsi cha Romex sichinthu choposa 14 gauge waya wokutidwa mu sheath yopanda chitsulo. Kuphimba uku kumathandiza kukoka chingwe kudzera m'makonde mofulumira, koma sikumakhudza mphamvu ya waya kuyendetsa magetsi. Romex 14/2 ndi 14/2 wokhazikika ndi ofanana ndipo ali ndi mphamvu yomweyo. Zotsatira zake, chingwe cha Romex 14/2 chitha kugwiritsidwa ntchito m'mabwalo pomwe waya wamba 14/2 angagwiritsidwe ntchito bwino. Izi zikutanthauza kuti 14/2 Romex imathanso kutulutsa magetsi pa 15 amp circuit. Komabe, muyenera kugwiritsanso ntchito chingwe champhamvu cha Romex polumikiza soketi kudera lomwe lili ndi ma amps opitilira 15 molingana ndi ma code amagetsi. (2)

Onani zina mwazolemba zathu pansipa.

• Waya wanji wa 30 amps 200 mapazi
• Kodi kukula kwa waya kwa chitofu chamagetsi ndi chiyani
• Ndi waya uti womwe ukuchokera ku batire kupita koyambira
