Mawaya mangani ari mu1/2 EMT?
Wanga uchiziva here kuti waya dzakawanda dzakatakura ikozvino dzakawandisa dzichaunza kupisa kwakakwana kunyungudutsa vinyl yekuvharisa, kugadzira njodzi yemoto?
Sekureva kweESFI, moto ungangoita 51,000, kukuvara kwe1,400, uye $ 1.3 bhiriyoni mukukuvadzwa kwepfuma kunoitika gore rega rega muUS nekuda kwekutsva kwemba. Huwandu uhu hunoratidza kuti iwe unofanirwa kuisa iyo wiring chaiyo kuchengetedza pfuma yako. Ndosaka ini ndichakudzidzisa nhamba chaiyo yewaya dze1 EMTs muchinyorwa changu.
Ini ndinokukurudzira kuti uenderere mberi nekuverenga kuti uone kuti ingani waya dzaunogona kupinda mune mamwe saizi etambo ducts:
Iwaya ngani dziri muconduit 1/2?
Huwandu hwewaya dzakasimba dzinogona kukwana mu ½-inch conduit inogara ichienderana nerudzi rwemhando yemagetsi yauri kushandisa.
Pane njodzi yekuti tambo dzakawandisa mukati megeji inotakura yakawandisa ikozvino dzinounza kupisa kwakakwana kunyungudutsa vinyl yekuputira pawaya dzakasimba, zvichigadzira njodzi huru yemoto. Kuzivikanwa kwakaringana kweiyo conduit zvinhu ndiyo nhanho yekutanga pakuona huwandu hwekuzadza.
Pausingakwanise kushandisa tambo yeNM kuchengetedza waya dzemagetsi dzisina chinhu, ndiyo nguva yaunoshandisa pombi yemagetsi sechinotsiva.
Mukoto wemagetsi une nhamba huru yetambo dzemagetsi dzinogona kufambiswa nepakati payo, ingave yakagadzirwa nesimbi yakaoma (EMT), purasitiki yakaoma (PVC conduit), kana simbi inochinjika (FMC). Conduit capacity chiyero chakatarwa neNational Electrical Code uye inoenderana neakawanda macode emuno anoita seyepamusoro-soro kodhi kodhi munzvimbo ipi neipi yakapihwa.
Kuti ikubatsire kuziva kuti mawaya mangani ari mu1 2 EMT, pazasi pane tafura kubva kuNational Electrical Code kuti ikubatsire kufamba:

Chii chiri nani, EMT kana PVC conduit?
Ndinogona kukubatsira kuita sarudzo ine ruzivo kana iwe uchikakavadzana pakati pemagetsi esimbi tubing nePVC tubing neEMT conduit. PVC nesimbi zvinodhura zvakanyanya kupfuura aruminiyamu EMTs, iyo zvakare yakasimba zvakanyanya uye yakasimba.
Heano mabhenefiti mashanu ekushandisa EMT aluminium:
- Kunyange zvazvo aluminium inorema 30% pasi pesimbi, yakasimba saizvozvo. Simbi inogona kuita brittle kana yakafumurwa kune yakaderera tembiricha, nepo aluminium inosimba.
- Aluminium inogona kuchekwa zviri nyore, kukotama kana kudhindwa pasina maturusi akakosha.
- Aluminium inodzivirira electromagnetic radiation, kudzivirira kupindira mune yako inonzwisa magetsi michina.
- Pamwe chete nekupisa, aruminiyamu inogonesa conductor yemagetsi. Iyo inogara yakachengeteka kune inobatwa, zvisinei nekupisa kana kutonhora kungave kunze.
- Humwe hunhu hwealuminium ndiko kushora kwayo. Aluminium inozvidzivirira pachayo nekugadzira iyo yakatetepa oxide coating kana yaiswa oksijeni. Nekuda kweizvozvo, haiparare sesimbi. Kuti uwedzere kudzivirira simbi kubva mukuora, vagadziri zvakare anodize iyo. (1)
