Imithetho Yekhodi Kagesi Kazwelonke Yezintambo Zangaphandle

I-NEC (Ikhodi Kagesi Kazwelonke) ihlanganisa izidingo eziningi eziqondile zokufakwa kwamasekethe angaphandle kanye nemishini.Ukuphepha okugxilwe kukho kuhilela ukuvikela umswakama nokugqwala, ukuvimbela ukulimala ngokomzimba, nokuphatha izindaba eziphathelene nokungcwaba ngaphansi komhlaba kwezintambo zangaphandle.Ngamaphrojekthi amaningi okufaka izintambo angaphandle kwezindawo zokuhlala, izidingo zekhodi ezifanele zifaka ukufaka izinto ezifakwa ngaphandle nezibani zokukhanyisa, bese usebenzisa izintambo ngaphezulu nangaphansi komhlaba.Izidingo zekhodi ezisemthethweni “ezisohlwini” eziphawuliwe zisho ukuthi imikhiqizo esetshenzisiwe kufanele igunyazelwe isicelo yi-ejensi yokuhlola egunyaziwe, efana ne-UL (ngaphambilini eyayaziwa ngokuthi yi-Underwriters Laboratories).

OkweZithako zikagesi zangaphandle

Imithetho eminingi esebenza ezindlini zezimpahla zangaphandle ingeyenhloso yokunciphisa ukuba nokwenzeka kokushaqeka, okuyingcuphe ephawulekayo engenzeka noma kunini lapho umsebenzisi ethintana ngqo nomhlaba.Imithetho eyinhloko yezimpahla zangaphandle ihlanganisa:

• Kudingeka ukuvikelwa kwesiphazamisi se-Ground Fault Circuit kuzo zonke izinto ezifakwa ngaphandle.Okuhlukile okukhethekile kungenziwa ekuncibilikeni kweqhwa noma okokusebenza kwe-deicing, lapho okokusebenza kunikwa amandla indawo yokuphuma engafinyeleleki.Ukuvikelwa kwe-GFCI okudingekayo kunganikezwa yizimpahla ze-GFCI noma ama-circuit breaker e-GFCI.
• Amakhaya kumele abe nesitsha esisodwa esingaphandle okungenani ngaphambili nangemuva kwendlu ukuze kube nokuthula kwengqondo.Kufanele zifinyeleleke kalula ukusuka phansi futhi zibekwe endaweni engaba ngaphezu kwamafidi angu-6 1/2 ngaphezu kwebanga (izinga eliphansi).
• Ovulandi namadekhi anamathiselwe anokufinyelela ngaphakathi (okuhlanganisa nomnyango ongaphakathi) kufanele abe nesitsha sokubeka esingekho ngaphezu kwamafidi angu-6 1/2 ngaphezu kwevulandi noma indawo yokuhamba yedekhi.Njengesincomo esijwayelekile, izindlu nazo kufanele zibe nesitsha sokugeza ohlangothini ngalunye lwe-balcony noma idekhi efinyeleleka phansi.
• Izimpahla ezisezindaweni ezimanzi (ngaphansi kwamakhava okuvikela, njengophahla lukavulandi) kufanele zimelane nesimo sezulu (WR) futhi zibe nekhava evikela isimo sezulu.
• Izimpahla ezihlala ezindaweni ezimanzi (ezichayeke esimeni sezulu) kufanele zimelane nesimo sezulu futhi zibe nekhava “esetshenziswayo” engamelana nesimo sezulu noma indlu.Le khava ivamise ukuhlinzeka ngokuvikeleka kwesimo sezulu esivaliwe ngisho nalapho izintambo zixhunywe esitsheni.
• Ichibi lokubhukuda elihlala njalo kufanele libe nokufinyelela esitsheni sikagesi esingasondeli kunamafidi angu-6 futhi engekho ngaphezu kwamafidi angu-20 ukusuka onqenqemeni lwechibi.Isitsha akumele sibe ngaphezu kwamafidi angu-6 1/2 ngaphezu kwedekhi yokubhukuda.Lesi sitsha kufanele sibe nesivikelo se-GFCI futhi.
• Izimpahla ezisetshenziselwa ukunika amandla amasistimu wokupompa kumachibi nama-spa akumele zisondele eduze kwamamitha angu-10 ukusuka ezindongeni zangaphakathi zechibi lokubhukuda elihlala unomphela, i-spa, noma ubhavu oshisayo uma singekho isivikelo se-GFCI esinikezwayo, futhi singasondeli ngaphezu kwamafithi angu-6 ukusuka ezindongeni zangaphakathi ichibi elihlala njalo noma i-spa uma zivikelwe i-GFCI.Lezi zimpahla kufanele zibe yizinto ezisetshenziswayo ezingasebenzisi amanye amadivayisi noma izinto zikagesi.

Okokukhanyisa kwangaphandle

Imithetho esebenza ekukhanyisweni kwangaphandle ngokuyinhloko imayelana nokusebenzisa izinto ezilinganiselwe ukuthi zisetshenziswe ezindaweni ezimanzi noma ezimanzi:

• Izinto ezikhanyayo ezindaweni eziswakeme (ezivikelwe i-eave elenga ngaphezulu noma uphahla) kufanele zifakwe ohlwini lwezindawo eziswakeme.
• Izinto ezikhanyayo ezindaweni ezimanzi/ezichalelekile kufanele zifakwe ohlwini ukuze zisetshenziswe ezindaweni ezimanzi.
• Amabhokisi kagesi abekwe phezulu azo zonke izinto zikagesi kumele angangeni noma angamelani nesimo sezulu. 
• Izibani zangaphandle azidingi ukuvikelwa kwe-GFCI.
• Amasistimu okukhanyisa ama-low-voltage kufanele afakwe ohlwini yi-ejensi yokuhlola egunyaziwe njengesistimu yonke noma ahlanganiswe kusukela kuzingxenye ezingazodwana ezisohlwini.
• Izakhiwo zokukhanya ezine-voltage ephansi (ama-luminaires) akumele ziqhele ngamamitha angu-5 ukusuka ezindongeni zangaphandle zamachibi, ama-spa, noma amabhavu ashisayo.
• Ama-transformer okukhanyisa ama-low-voltage kumele abe ezindaweni ezifinyeleleka kalula.
• Amaswishi okulawula amanzi okubhukuda noma izibani ze-spa noma amaphampu kufanele abekwe okungenani amafidi angu-5 ukusuka ngaphandle kwezindonga zechibi noma i-spa ngaphandle uma ehlukaniswe nephuli noma i-spa ngodonga.

Okwamakhebuli namaConduits angaphandle

Ngisho noma ikhebula le-NM elivamile linejakhethi yangaphandle ye-vinyl kanye nokufakwa kwamanzi okungangeni emanzini eduze kwezintambo zokushayela ngazinye, akuhloselwe ukusetshenziswa ezindaweni ezingaphandle.Kunalokho, izintambo kufanele zigunyazwe ukusetshenziswa ngaphandle.Futhi uma usebenzisa i-conduit, kunemithetho eyengeziwe yokulandela.Imithetho esebenzayo yamakhebuli angaphandle namapayipi imi kanje:

• Izintambo/ikhebula elivuliwe noma eligqitshiwe kufanele lifakwe ohlwini ukuze lisetshenziswe.Ikhebula lohlobo lwe-UF yikhebula elisetshenziswa kakhulu elingelona elensimbi kumarun okufaka izintambo angaphandle.
• Ikhebula le-UF lingangcwatshwa ngokuqondile (ngaphandle kwepayipi) okungenani ngamayintshi angu-24 ekhava yomhlaba.
• Izintambo ezigqitshwe ngaphakathi kwensimbi eqinile (RMC) noma ipayipi lensimbi (i-IMC) kufanele okungenani libe namayintshi angu-6 ekhava yomhlaba;izintambo epayipini le-PVC kumele okungenani zibe namayintshi angu-18 ekhava.
• I-backfill ezungezile noma izintambo kufanele zibe izinto ezibushelelezi ezibushelelezi ngaphandle kwamatshe.
• Izintambo ezine-voltage ephansi (ezingadluli ama-volts angu-30) kufanele zingcwatshwe okungenani ngama-intshi angu-6 ukushona.
• Izintambo ezingcwatshiwe zigijima lolo shintsho olusuka ngaphansi komhlaba luye ngaphezu komhlabathi kufanele luvikelwe epayipini kusukela ekujuleni kwekhava okudingekile noma amayintshi angu-18 (noma yikuphi okungaphansi) ukuya endaweni yayo yokuqeda ngaphezu komhlabathi, noma okungenani amafidi angu-8 ngaphezu kwebanga.
• Izintambo zesevisi kagesi ezilenga echibini, i-spa, noma ubhavu oshisayo kufanele okungenani zibe ngamafidi angu-22 1/2 ngaphezu kwamanzi noma indawo yeplathifomu yokutshuza.
• Izintambo zokudlulisa idatha noma izintambo (ifoni, i-inthanethi, njll.) kufanele okungenani zibe ngamafidi angu-10 ngaphezu kobuso bamanzi emachibini, eziphaleni, nasezindaweni ezishisayo.
