Amathreyi ekhebulaziyizingxenye ezibalulekile ekufakweni kukagesi, zihlinzeka ngendlela ehlelekile yokuxhuma izintambo zikagesi kanye nezintambo. Phakathi kwezinhlobo ezahlukene zamathileyi ekhebula, amathileyi ekhebula amboziwe abaluleke kakhulu ekuvikeleni izintambo ezicini zemvelo kanye nomonakalo ongokwenyama. Ukuqonda imithethonqubo ye-National Electrical Code (NEC) mayelana namathileyi ekhebula kubalulekile ekuqinisekiseni ukuphepha kanye nokuthobela imithetho ezinhlelweni zikagesi.
I-NEC, ebuyekezwa njalo eminyakeni emithathu, ichaza izidingo ezithile zokufakwa nokusetshenziswa kwamathileyi ekhebula ku-Athikili 392. Lesi sihloko sinikeza iziqondiso mayelana nokuklama, ukufakwa, kanye nokugcinwa kwamathileyi ekhebula, kufaka phakathi amathileyi ekhebula amboziwe. Ngokusho kwe-NEC, amathileyi ekhebula kumele akhiwe ngezinto ezifanele indawo afakwe kuyo. Lokhu kufaka phakathi izinto ezicatshangelwayo zokumelana nokugqwala, izilinganiso zomlilo, kanye nomthamo wokuthwala umthwalo.
Esinye sezici ezibalulekile zekhodi ye-NEC yeamathreyi ekhebulaiyimfuneko yokufakwa kwesisekelo nokubopha okufanele. Amathreyi ekhebula amboziwe kumele afakwe phansi ukuze kuvinjelwe izingozi zikagesi, kanti i-NEC ichaza izindlela zokufeza ukufakwa kwesisekelo okuphumelelayo. Ngaphezu kwalokho, ikhodi iyalela ukuthi amathreyi ekhebula amboziwe afakwe ngendlela evumela umoya owanele kanye nokushabalaliswa kokushisa, okubalulekile ekugcineni ubuqotho bezintambo ezifakwe ngaphakathi.
Ngaphezu kwalokho, i-NEC igcizelela ukubaluleka kokugcina ukufinyelela okucacile kumathileyi ekhebula ngezinjongo zokuhlola nokulungisa. Lokhu kubaluleke kakhulu kumathileyi ekhebula amboziwe, njengoba engavimba ukubonakala kwezintambo ezingaphakathi. Ukubhalwa kahle kwamalebula kanye nokubhalwa kwezintambo ezingaphakathi kwethileyi nakho kuyadingeka ukuze kube lula ukulungiswa nokuxazulula izinkinga esikhathini esizayo.
Ngamafuphi, ikhodi ye-NEC yamathreyi ekhebula, kufaka phakathiamathreyi ekhebula amboziwe, iklanyelwe ukuqinisekisa ukuphepha, ukuthembeka, kanye nokusebenza kahle ekufakweni kukagesi. Ukunamathela kule mithetho akugcini nje ngokuvikela ubuqotho bohlelo lukagesi kodwa futhi kuthuthukisa ukuphepha kwendawo olusebenza kuyo.
