Nheyo dzemagetsi dzemagetsi uye dzakakurudzirwa maitiro ekugadziridza kwekicheni kazhinji dzinoita semitemo isina zvazvinobatsira yakabikwa muhofisi yehofisi, sezvo magetsi emagumo anogadziriswa kunze kwematafura emunamato. Zvizhinji zvavo, zvisinei, zvinobva kuvanhu vanoshanda mumunda: magetsi, makontrakta, uye mamwe mashizha emhizha.
Aya mazano anokurudzira US National Fire Protection Association (NFPA).
Iri ndiro boka rinonyora National Electrical Code (NEC), iro rinogamuchirwa zvachose kana kuti chikamu nemunharaunda wako.
Saka zvinopfuura kungoita kuti muongorori wenguva yenyu afare kupfuura chero chimwe chinhu. Kunze kwekunyengedza, kodeti inonyatsotaura chete zvishoma. Iyo NFPA inovandudza code imwe yemakore matatu kuti iwane zvinowedzera zvinodiwa zvekishi rino . Uripo iye zvino ane kodeti here?
GFCI-Protected Small Appliance Circuits
Chidimbu : Ipai masendimita makumi maviri nemakumi maviri, 120-volt kuti ipe simba kuGFCI (Ground Fault Circuit Interrupter) zvipfeko zvepamusoro uye nzvimbo dzinodya.
Chikonzero nei : Mazamu makumi maviri anokwana (vs. 15 amp) zvemasimba ane simba anowanikwa mumakishi. Funga nezvekuchenesa ovens, blenders, uye mixers. Izvo "chikamu" chechipiri chinodiwa chinopararira nzvimbo inoshandiswa, kunyange isiri iyo yose mutoro, sezvo zvose zviri zviviri zvingave pane imwe chete dunhu. Kupa purogiramu kazhinji purogiramu kwenguva refu kwave kuri kushanda kweN NEC kuitira kuti varidzi vepamba vasaedzwa kuti vatambanudze tambo dzemagetsi kure.
Basic Lighting Circuit
Chidimbu : Ipai nharaunda imwechete 15-amp, 120-volt inopa chigadziko chemwenje , magetsi akadzivirirwa , uye chero magetsi emabhasikiti. Izvi hazvikwanisi kuva paGFCI mutariri.
Chikonzero nei : Zvishoma zvishoma zvinoshandiswa pakugadzirisa chiedza; zvisinei, kana iwe uchida kuwedzera kujekesa, iwe unofanirwa kuunza hurumende, nezvimwe zvinoshandiswa nemushandi, zvakadai sematareji ematare, nezvimwe, kuti uwane zvido izvozvo.
Izvo "chimwe" chinodiwa ndechekuti vashoma vasati vaona kuti makikani ane anga rimwe rudzi rwemwenje unogara nokusingaperi. Pakupedzisira, kana magetsi aive paGFCI, vangave vagoerekana vabviswa.
Kureba pakati peGFCIs Over Countertops
Chidimbu : Unofanirwa kubvumira zvisati zvasvika masendimita makumi mashanu pakati pemakona.
Chikonzero : Chinangwa ndechokuti muridzi weimba haafaniri kuedzwa kuti atambanudze tambo kupfuura masendimita makumi maviri (kureva, hafu yezvinodiwa 48 masendimita) kuitira kuvhara mune zvigadzirwa zviduku. Iwe unogona kupa GFCIs kakawanda kupfuura dzose 48 masendimita, iyo inowanzoonekwa seyakakurudzirwa.
Tamper-Resistant Outlets
Chidimbu : Zvose zvikamu 15 nemazana makumi maviri nemakumi masere, kana GFCI kana kuti kwete, inofanira kunge isina kudzivirirwa munzvimbo dzinotevera dzinoshandiswa nekicheni: dunhu rekushandisa shoma, nzvimbo yepamusoro, nzvimbo yepamusoro, nzvimbo yekugara.
Sei : Kana iwe usina kuita magetsi kwemakore mashomanana, unogona kushamiswa nezvinodiwa. Kana iwe wakatenga imba yakwegura, pane mukana wekuti imba yako haina chimwe chezvinhu izvi zvakakosha.
Kugadzirisa dambudziko revana vanozvitsakatisa nekunamatira zvinhu (paper clips, bobby pini, nezvimwewo) muzvivako, NEC yakatanga kuda kuiswa kwezvitsuwa zvine "shutter" yakasimba mukati.
Ichi chakavhara chinogona kuvhurwa apo magetsi maviri emagetsi anoputirwa mune imwe nzvimbo panguva imwechete - uye nesimba guru. Aya mabhuku anozivikanwa netsamba "TR" pajoko rinotangira rekubuda.
Countertop Zvikamu Zvishoma Kupfuura Masendimita Akawanda Anoda GFCI
Chidimbu : Countertop zvikamu zvinopfuura 12 masendimita akaenzana zvinonzi se "rusvingo" uye inofanira kuva nechigamba (GFCI).
Sei : Vanhu vanoita zvinhu zvemarudzi ose muzvikamu zviduku zvepaikiriti, kusanganisira kuedza kuisa mumidziyo miduku. Iyi "masendimita gumi nemaviri" inodikanwa inovimbisa kuti chero chipi nechimwe-simba chinotora-chinotora chinogadzika ipapo chichava nesimba rayo.
Dishwasher Circuit
Chidimbu : Ipai imwe 15-amp, 120-volt yedunhu rakatsaurirwa rakafambiswa neka 14/2 cable. Haafaniri kuva GFCI.
Sei : "Akazvitsaurira" ndiro shoko rinokosha. Izvi zvinoreva kuti mudzidzi wemashambadziro anowana dunhu rake uye haagoni kuenda nenzira inokurumidza (panharaunda yedunhu), nokudaro achivhara simba kune dzimwe nzvimbo dzekicheni.
Kungoerekana kusvetuka zvakare chikonzero chacho kwete GFCI. Pakupedzisira, 14/2 ndiyo yakavhara yekambo ye 15-amp circuit.
Kurasikirwa Kwemarara Dunhu
Chidimbu : Ipai imwe 15-amp, 120-volt yedunhu rakatsaurirwa rakafambiswa neka 14/2 cable. Haafaniri kuva GFCI.
Chikonzero nei : Chikonzero chechi ichi chakafanana nechikonzero sechikwata chekuchenesa, pamusoro apa. Vanotsva marara havakwanisi kupera, sezvakaita mitsara kana microwaves. Kutanga kwokutanga kwakakwirira zvakanyanya zvokuti kunogona kutama nyore nyore kubva kune rimwe divi rinoputika, nokudaro kuvhara zvimwe zvigadzirwa mukicheni.
Microwave Circuit
Chidimbu : Ipai imwe 20-amp, 120-volt yedunhu rakatsaurirwa rakafambiswa nekambo 12/2. Haafaniri kuva GFCI.
Chikonzero nei : The 20 amp circuit inotarisirwa kushandisa simba rakakwirira rinodiwa re microwaves. A 12-gauge cable inowanikwa kune rimwe divi 20-amp.
Electric Range Circuit
Chidimbu : Ipai imwe 50-amp, 120/240-volt yakazvitsaurira dunhu yakakomberedzwa nekwakanyatsosimbiswa netambo yecambo. Izvi hazvifaniri kuva GFCI.
Chikonzero nei : Magetsi anowedzera simba rakawanda mukicheni kudarika chero chinhu chipi zvacho. Saka, zvinhu zvose pamusoro penharaunda iyi zvakakura-siyana uye zvakasanganiswa: mafuta akavhara, big-amp circuit breakers, uye dunhu rakatsaurirwa kuitira kuti usashanya mamwe magetsi kana magetsi.
