Ngokuqaliswayo, i-NM-B cable ingasemva ngenxa yokuba iyinhlobo elihlobene neentshaba. Ikhishwe ngokugcina ukusuka kwisebe esebenza ngokukhala ngokukhona. Yinto engeze kakhulu, ungavumelana ngokukhona ukuba amathswa akho aqhubekelwe kusemisweni futhi akuzange azibuyekeze umphathisi wendlu. Ngokulandelayo, i-NM-B cable yakhiwe ngokukhona ukuba kukhona kunye nokuba kuyahlaleka. Ukusetyenziswa kufuneka kube ngaphandle kokuhambisana: imodikhasi yesixhenxe sithile sokuba sehlalelwa namanye amaxesha. Ngokwesobizo, ungavumelana ukuba lingahlinzelwa ukuba ilungisele ndlu yakho kusemisweni kunye nokuhlola kwindawo ekubeni.
Cima: Ukugqiba okubhaliweyo kuzokufuneka uziphele ekuphakamisayo amakhanda emahlweni wezinye zezicatulo. Lolu hlangothi, uzoba ukuya ngenqanawezi yokuzipha amaxwebhu. Ngoko ke ndawonye ngokuhlonishwa xa ungene lapho ukuba ungathintele ukuthi usetyenziswa amacatulo apho akukho abaqhelwe ngazo ngokushesha.
Namhlanje xa izicatulo zilayishwa kunye nokulondoloza, uzivumele kuqaphele kumahluko nezinye izinto lokugcina ukuthi bayenza ubucopho babuyekezo lwesinqumo. Usagqibile ukusebenzisa amaxwebhu amancane lokuxhumana ukuthi wonke umdlulwe kunye nokuthi usaphinde. Ukufaka kabusha imigijimi yezigidi ezincinci ezikhulu ezikhulu ezintsha kunye nokuthi ezithile. Lokhu kungaba kuhlonela ukuthi akukho imigomo yomthimba yokuncedeka phambi komhlawulo wesikhashana.
Romex: Romex ngumthengiso wesetyenziso esifanekayo nge NM-B esizethentha kwiqhutywa. Lokhu luhlukwe ngokushesha ngamabhedlela amaningi aluhlukileyo kwindawo, njengecabe yezindlela ye NM-B. Ngokugcina, i-Romex iyenza ngokubonisa njalo njengecabe ye NM-B, kunye neziqephu zombini ezithathelwe ngokwesigaba lesithi.
I-Conduit — Yilinye ilenye lenzima lokuthi lekho through imibhalo yemetal okanye iphesa. Oku kungcono ukusetshenziswa e-DS Smith ngokulula kunye nokusetyenziswa komsebenzi kunye nokusebenza. Ngaphandle kokuba kukho umthengiso omncane kunye nokuzipha izinyathelo, i-conduit icinzela uphawu olupheleleyo lwamabhedlela — olufunekelayo ngokwesigaba sokuxhasa emagumbeni ekwangaphakathi.
ICable ye-BX — Lento ingakwazi ukusetshenziswa ngokubanzi, kunye nokuba yayingakanani. Kuna sheethi sometal esihlalene namabhedlela ahlukene, ucable we BX ungenzi ngokubonisa, kodwa ayahluleka kunye nokuphuma ngokushesha (njengecabe yenye yenze NM-B), kunye nokuthi kusenziwe ngokubonisa kakhulu.
Funa ukubuka kwiqinisekiso ye: Ukuphenduleka okuthile kwesicatulo, kunye nokuba ngokushaya amathswa angaphakathi. Oku kungaba yinto eyenzeka ngamaxesha apho amathswa akukho amagalayi engaphezulu njengazo zingezantsi, lokhu lizama ukwenzela ngokubanzi kakhulu xa uvumelela amacatulo amaninzi.
