Amategeko y’igihugu y’amashanyarazi agenga insinga zo hanze

NEC (Code of National Electrical Code) ikubiyemo ibisabwa byinshi byihariye byo gushyiraho imiyoboro yo hanze n'ibikoresho.Umutekano wibanze byibanze ku gukingira ubushuhe no kwangirika, kwirinda kwangirika kwumubiri, no gucunga ibibazo bijyanye no gushyingura mu nsi kugirango insinga zo hanze.Hamwe nimishinga myinshi yo guturamo yo hanze, ibyangombwa bisabwa kode irimo gushyiramo ibyuma byo hanze no gucana amatara, hamwe no gukoresha insinga hejuru no munsi yubutaka.Ibisabwa kode yemewe iri hamwe na "urutonde" byavuzwe bivuze ko ibicuruzwa byakoreshejwe bigomba kwemererwa kubisaba n'ikigo cyemewe cyemewe, nka UL (Laboratoire zahoze zandika).

Kubyakira Amashanyarazi Hanze

Amenshi mu mategeko akurikizwa ahacururizwa hanze hagamijwe kugabanya amahirwe yo guhungabana, ibyo bikaba ari ingaruka zishobora kuba igihe cyose umukoresha ahuye nisi.Amategeko yingenzi yo kwakirwa hanze harimo:

• Kurinda Impamvu Yumuzunguruko Kurinda birakenewe kubintu byose byakirwa hanze.Ibidasanzwe birashobora gukorwa kubikoresho byo gushonga urubura cyangwa gushushanya, aho ibikoresho bikoreshwa nubucuruzi butagerwaho.Kurinda GFCI gusabwa birashobora gutangwa na GFCI yakira cyangwa GFCI yameneka.
• Inzu zigomba kugira ibyakirwa hanze byibuze byibuze imbere ninyuma yinzu kugirango amahoro yumutima.Bagomba kuba byoroshye kuboneka kubutaka kandi bigashyirwa hejuru ya metero 6/2 hejuru yicyiciro (urwego rwubutaka).
• Gufatanije na balkoni hamwe nigorofa hamwe n’imbere (harimo umuryango winjira mu nzu) bigomba kuba byakira bitarenze metero 6/2 hejuru ya balkoni cyangwa hejuru yurugendo.Nkicyifuzo rusange, amazu nayo agomba kugira reseptacle kuruhande rwa balkoni cyangwa igorofa igera kubutaka.
• Ibyakirwa ahantu hatose (munsi yuburinzi, nkigisenge cyibaraza) bigomba kuba birwanya ikirere (WR) kandi bifite igifuniko kitarinda ikirere.
• Ibyakirwa ahantu hatose (byerekanwa nikirere) bigomba kuba birwanya ikirere kandi bikagira igifuniko cyangiza ikirere "gikoreshwa" cyangwa amazu.Igifuniko ubusanzwe gitanga ikirere gifunze nubwo imigozi icomekwa muri resept.
• Ikidendezi gihoraho cyo koga kigomba kuba gifite amashanyarazi yakirwa kitarengeje metero 6 kandi kitarenze metero 20 uvuye kuruhande rwa pisine.Kwakira ntibigomba kuba hejuru ya metero 6/2 hejuru yikidendezi.Iyi resept igomba kuba ifite uburinzi bwa GFCI.
• Ibyakiriwe bikoreshwa mumashanyarazi ya pompe kubidendezi na spas ntibigomba kuba hafi ya metero 10 uvuye kurukuta rwimbere rwa pisine ihoraho, spa, cyangwa igituba gishyushye niba nta burinzi bwa GFCI butangwa, kandi ntibureshya na metero 6 uvuye kurukuta rwimbere rwa pisine ihoraho cyangwa spa niba arinzwe GFCI.Ibi byakira bigomba kuba ibyakirwa kimwe bidakoresha ibindi bikoresho cyangwa ibikoresho.

Kumurika Hanze

Amategeko akurikizwa kumatara yo hanze ahanini yerekeranye no gukoresha ibikoresho byapimwe kugirango bikoreshwe ahantu hatose cyangwa huzuye:

• Ibikoresho byoroheje ahantu hatose (harinzwe na eave cyangwa igisenge kirenze) bigomba gutondekwa ahantu hatose.
• Ibikoresho byoroheje mubice bitose / byerekanwe bigomba gutondekwa kugirango bikoreshwe ahantu hatose.
• Agasanduku k'amashanyarazi gashyizwe hejuru yamashanyarazi kubikoresho byose byamashanyarazi bigomba kuba bitaguye imvura cyangwa ikirere. 
• Ibikoresho byo kumurika hanze ntibisaba kurinda GFCI.
• Sisitemu yo kumurika amashanyarazi make igomba gutondekwa nikigo cyemewe cyo gupima nka sisitemu yose cyangwa igateranyirizwa hamwe mubice bigize urutonde.
• Ibikoresho bito bito bito (luminaire) ntibigomba kuba hafi ya metero 5 uvuye kurukuta rwo hanze rwibidendezi, spas, cyangwa igituba gishyushye.
• Guhindura amatara mato mato agomba kuba ahantu hagaragara.
• Guhindura kugenzura pisine cyangwa amatara ya spa cyangwa pompe bigomba kuba byibuze metero 5 uvuye kurukuta rwo hanze rwa pisine cyangwa spa keretse iyo bitandukanijwe na pisine cyangwa spa kurukuta.

Ku nsinga zo hanze hamwe nuyoboro

Nubwo umugozi usanzwe wa NM ufite ikoti yo hanze ya vinyl hamwe nudukingirizo twamazi adafite amazi hafi yumuntu ukora insinga, ntabwo agenewe gukoreshwa ahantu hanze.Ahubwo, insinga zigomba kwemererwa gukoreshwa hanze.Kandi iyo ukoresheje umuyoboro, hari amategeko yinyongera yo gukurikiza.Amategeko akurikizwa kumigozi yo hanze nuyoboro ni nkibi bikurikira:

• Kugaragara cyangwa gushyingurwa insinga / umugozi bigomba gutondekwa kubisabwa.Ubwoko bwa UF ni umugozi usanzwe ukoreshwa utari metallic insinga zo guturamo hanze.
• Umugozi wa UF urashobora gushyingurwa mu buryo butaziguye (nta muyoboro) ufite byibura santimetero 24 z'ubutaka.
• Umugozi ushyinguwe imbere mucyuma gikomeye (RMC) cyangwa umuyoboro wo hagati (IMC) ugomba kuba ufite byibura santimetero 6 zubutaka;insinga mu muyoboro wa PVC igomba kuba ifite byibura santimetero 18 z'igifuniko.
• Gusubiza inyuma umuyoboro cyangwa insinga bigomba kuba byoroshye granular idafite amabuye.
• Umuyoboro muto wa voltage (utwara bitarenze 30 volt) ugomba gushyingurwa byibuze santimetero 6.
• Umuyoboro ushyinguwe uva mu nsi ujya hejuru yubutaka ugomba kurindwa mu muyoboro uva ku burebure busabwa cyangwa santimetero 18 (iyo ari nto) kugeza aho urangirira hejuru yubutaka, cyangwa byibura metero 8 hejuru yicyiciro.
• Amashanyarazi ya serivise yumuriro hejuru yicyuzi, spa, cyangwa igituba gishyushye bigomba kuba byibura metero 22/2 hejuru yubuso bwamazi cyangwa hejuru yikibuga.
• Umugozi wohereza amakuru cyangwa insinga (terefone, interineti, nibindi) bigomba kuba byibura metero 10 hejuru yubuso bwamazi muri pisine, spas, hamwe nigituba gishyushye.
