Kedu waya ole dị na 1/2 EMT?

19.02.2023 /

Ị maara na ọtụtụ wires na-ebu oke ugbu a ga-emepụta okpomọkụ zuru oke iji gbazee mkpuchi vinyl, na-emepụta ihe ize ndụ ọkụ?

Dị ka ESFI si kwuo, ihe dị ka ọkụ 51,000, mmerụ ahụ 1,400 na ihe onwunwe $1.3 ijeri na-eme kwa afọ na US n'ihi ọkụ ụlọ. Ndekọ ọnụ ọgụgụ ndị a na-egosi na ị ga-etinyerịrị wiwi ziri ezi iji chekwa ihe onwunwe gị. Ọ bụ ya mere m ga-eji kụziere gị ọnụọgụ waya ziri ezi maka 1 EMT na edemede m.

    Ana m akwado ka ị gaa n'ihu na-agụ iji chọpụta ọnụọgụ waya ị nwere ike dabara na nha ndị ọzọ nke eriri USB:

    Kedu waya ole dị na 1/2 conduit?

    Ọnụ ọgụgụ nke wires siri ike nke nwere ike dabara na ½-inch conduit ga-adabere mgbe niile n'ụdị eriri eletrik ị na-eji.

    Enwere ihe ize ndụ na ọtụtụ eriri dị n'ime oghere na-ebu oke ugbu a ga-emepụta okpomọkụ zuru oke iji gbazee mkpuchi vinyl na wires siri ike, na-emepụta nnukwu ihe ize ndụ ọkụ. Ịmata n'ụzọ ziri ezi ihe ndị na-ebu ụzọ bụ nzọụkwụ mbụ n'ịchọpụta ike njuputa.

    Mgbe ị nweghị ike iji eriri NM chebe waya eletrik ekpughere, nke a bụ oge ị na-eji eriri eletrik dị ka nnọchi.

    Igwe ọkụ eletrik nwere ọnụọgụ eletrik kachasị elu nke enwere ike isi na ya, ma ọ bụ ígwè siri ike (EMT), plastik siri ike (PVC conduit), ma ọ bụ ígwè na-agbanwe agbanwe (FMC). Ikike ikuku bụ ọkwa nke National Electric Code hibere ma kwekọọ n'ọtụtụ koodu mpaghara, nke na-eme dị ka ụkpụrụ nchịkwa n'ọnọdụ ọ bụla.

    Iji nyere gị aka ịma ole wires dị na 1 2 EMT, n'okpuru bụ tebụl sitere na Koodu Eletriki Mba iji nyere gị aka duzie gị:

    Kedu nke ka mma, EMT ma ọ bụ PVC conduit?

    Enwere m ike inyere gị aka ịme mkpebi mara ọkwa ma ọ bụrụ na ị na-arụ ụka n'etiti ọkpọkọ igwe eletrik na tubing PVC na ụzọ EMT. PVC na ígwè dị oke ọnụ karịa aluminom EMT, nke dịkwa ike ma na-adịgide adịgide.

    Nke a bụ uru ise nke iji EMT aluminum:

    • Ọ bụ ezie na aluminom na-eru 30% na-erughị ígwè, ọ dịkwa ike. Ígwè nwere ike na-akụkụ ma ọ bụrụ na oyi na-atụ, ebe aluminom na-esiwanye ike.
    • Enwere ike ịkpụ aluminom ngwa ngwa, gbadaa ma ọ bụ stampụ na-enweghị ngwaọrụ pụrụ iche.
    • Aluminom na-echebe radieshon electromagnetic, na-egbochi nnyonye anya na ngwa eletriki gị nwere mmetụta.
    • Tinyere okpomọkụ, aluminom bụ ezigbo onye nduzi nke ọkụ eletrik. Ọ na-adị mma na mmetụ aka n'agbanyeghị otú ọ ga-esi dị ọkụ ma ọ bụ oyi n'èzí.
    • Àgwà ọzọ nke aluminom bụ nguzogide corrosion ya. Aluminom na-echebe onwe ya site n'ịmepụta mkpuchi oxide dị mkpa mgbe ekpughere ya na ikuku oxygen. N'ihi nke a, ọ bụghị n'okpuru corrosion dị ka ígwè. Iji kpuchido ígwè ahụ site na corrosion, ndị na-emepụta ihe na-edozikwa ya. (1)
