Kufunika kwa Kutsatira Malamulo a Nyumba Zamalonda
Nyumba zamalonda ziyenera kutsatira malamulo okhwima okhudza chitetezo cha moto. Ma Fiber Optic Enclosures Omwe Amayikidwa Moto amagwira ntchito yofunika kwambiri pakukwaniritsa zofunikira izi. Kusatsatira malamulo kungayambitse mavuto aakulu:
- Kukana madandaulo a inshuwaransi chifukwa cha kutayika kwa moto
- Kuwonjezeka kwa ndalama za inshuwaransi pambuyo pofufuza
- Zoletsa kapena zochotsera zomwe zilipo
- Kuletsa mfundo zomwe zingachitike chifukwa cha kuphwanya malamulo kwakukulu
- Zilango ndi ma quotation ochokera ku mabungwe olamulira kapena ozimitsa moto
- Malamulo okonza zinthu omwe angalepheretse bizinesi kugwira ntchito
- Ndalama zokonzera zinthu zadzidzidzi zomwe zimaposa bajeti yomwe idakonzedwa

Zofunikira za NEC Article 770 ndi NFPA 70
Nkhani 770 ya National Electrical Code (NEC) ndi NFPA 70 zimakhazikitsa maziko a chitetezo cha moto pakupanga ma fiber optic. Malamulo awa amafuna kuti ma Fiber Optic Enclosures ndi ma cable asamawonjezere chiopsezo cha moto kapena kufalikira kwa utsi mkati mwa nyumba. Okhazikitsa ayenera kuletsa kulowa konse kudzera m'makoma, pansi, ndi padenga pogwiritsa ntchito njira zovomerezeka. Izi zimasunga mulingo wokana moto wa chotchinga chilichonse. Ma waya ayenera kuyikidwa bwino, pogwiritsa ntchito zida zomwe zimapewa kuwonongeka. M'malo ogwirira mpweya, ma waya osakhala achitsulo ayenera kukhala ndi utsi wochepa komanso mphamvu zotulutsa kutentha.
Mbali yofunika kwambiri yotsatirira malamulo ndi kusankha mtundu woyenera wa chingwe pa malo aliwonse omanga nyumba. NEC imagawa zingwe za ulusi wa kuwala potengera kukana kwawo moto ndi mawonekedwe a utsi. Gome ili pansipa likufotokoza mwachidule mitundu ya zingwe zomwe zimaloledwa m'malo enaake:
