Ndi mawaya angati omwe ali mu 1/2 EMT?

Kodi mumadziwa kuti mawaya ochuluka omwe amanyamula mphamvu yamagetsi amatha kutentha mokwanira kuti asungunuke chophimba cha vinilu, kuchititsa ngozi yamoto?

Malinga ndi ESFI, pafupifupi moto wa 51,000, kuvulala kwa 1,400, ndi $ 1.3 biliyoni pakuwonongeka kwa katundu kumachitika chaka chilichonse ku US chifukwa cha moto wanyumba. Ziwerengerozi zikutsimikizira kuti muyenera kukhazikitsa mawaya olondola kuti muteteze katundu wanu. Ichi ndichifukwa chake ndikuphunzitsani mawaya olondola a 1 EMTs m'nkhani yanga.

Ndikukulimbikitsani kuti mupitilize kuwerenga kuti mudziwe kuchuluka kwa mawaya omwe mungakwane mumitundu ina ya ma ducts a chingwe:

Ndi mawaya angati omwe ali mu ngalande 1/2?

Chiwerengero cha mawaya olimba omwe amatha kulowa mu ngalande ya ½-inch nthawi zonse zimatengera mtundu wanji wamagetsi omwe mukugwiritsa ntchito.

Pali chiwopsezo chakuti zingwe zambiri mkati mwa ngalande yonyamula madzi zimatha kuyambitsa kutentha kokwanira kusungunula zokutira za vinyl pa mawaya olimba, zomwe zimapangitsa kuti pakhale ngozi yayikulu. Kuzindikiritsa koyenera kwa zinthu za ngalande ndiye gawo loyamba lodziwira kuchuluka kwa kudzaza.

Pamene simungathe kugwiritsa ntchito chingwe cha NM kuteteza mawaya amagetsi otuluka, iyi ndi nthawi yomwe mumagwiritsa ntchito ngalande yamagetsi m'malo mwake.

Njira yamagetsi imakhala ndi zingwe zambiri zamagetsi zomwe zimatha kudutsamo, kaya ndi zitsulo zolimba (EMT), pulasitiki yolimba (PVC conduit), kapena flexible metal (FMC). Conduit capacity ndi muyeso wokhazikitsidwa ndi National Electrical Code ndipo imagwirizana ndi ma code ambiri am'deralo omwe amakhala ngati ma code apamwamba kwambiri pamalo aliwonse.

Kukuthandizani kudziwa mawaya angati omwe ali mu 1 2 EMT, pansipa pali tebulo lochokera ku National Electrical Code kukuthandizani kuyenda:

kukula	Mtundu wa pipeline	14 awg	12 awg	10 awg	8 awg
	EMT	12	9	5	3
1/2 inchi	Zithunzi za PVC-40	11	8	5	3
	Zithunzi za PVC-80	9	6	4	2
	FMC	13	9	6	3
	EMT	22	16	10	6
3/4 inchi	Zithunzi za PVC-40	21	15	9	5
	Zithunzi za PVC-80	17	12	7	4
	FMC	22	16	10	6
	EMT	35	26	16	9
1-inchi	Zithunzi za PVC-40	34	25	15	9
	Zithunzi za PVC-80	28	20	13	7
	FMC	33	24	15	9

Chabwino n'chiti, EMT kapena PVC conduit?

Nditha kukuthandizani kupanga chisankho mwanzeru ngati mukukangana pakati pa chubu chachitsulo chamagetsi ndi machubu a PVC ndi ngalande ya EMT. PVC ndi zitsulo ndizokwera mtengo kwambiri kuposa ma EMTs a aluminiyamu, omwenso ndi amphamvu kwambiri komanso okhalitsa.

Nazi maubwino asanu ogwiritsira ntchito aluminiyamu ya EMT:

• Ngakhale kuti aluminiyamu imalemera 30% kucheperapo kuposa chitsulo, ndi yolimba chimodzimodzi. Chitsulo chikhoza kukhala chosalimba chikatenthedwa ndi kutentha pang'ono, pamene aluminiyumu imakhala yamphamvu.
• Aluminium imatha kudulidwa mosavuta, kupindika kapena kusindikizidwa popanda zida zapadera.
• Aluminiyamu imateteza ma radiation a electromagnetic, kuteteza kusokoneza kwa zida zanu zamagetsi.
• Pamodzi ndi kutentha, aluminiyumu ndi conductor wabwino kwambiri wamagetsi. Zimakhala zotetezeka kuzikhudza, ngakhale kunja kumatentha kapena kuzizira bwanji.
• Ubwino wina wa aluminiyumu ndi kukana dzimbiri. Aluminiyamu imadziteteza mwachilengedwe popanga zokutira zopyapyala za okosijeni zikakumana ndi okosijeni. Chotsatira chake sichimawononga ngati chitsulo. Pofuna kuteteza zitsulo kuti zisawonongeke, opanga nawonso anodize. (1)

Onani zina mwazolemba zathu pansipa.

• Waya wanji wa 30 amps 200 mapazi
• Momwe mungatsekere mawaya amagetsi
• Momwe mungapangire mawaya amagetsi mchipinda chapansi chosamalizidwa
