Tsara Masu Aiki Da Abubuwan Da Ake Nuna A Cikin Takarda Ta Aiki Don In Tsara Ingantaccen Gini Da Za A Yi Aiki. Daga hanyoyin da ake nuna, gini da ke faruwar da kofin kasa daga take da suka biyo ana da 1.5m, da kuma kofin kasa ta farko, ana da 1.8m. Amma wannan gini yana iya canza da tsirin idan an yi la'akari mai aiki. Muhimman abu, a cikin wata aiki, musamman a cikin wurin da adi (kamar mallamsu, wasu sukan kansu, ko kuma masanin karkashin da suka da kofin kasa da suka biyu), gini da za a yi aiki yana da kyau a zama daidai.
Yi Kofin Kasa Da Cikakken Da Aikinsu, Da Kuma Zaba Holes Da Cikakken. Aikin kofin kasa yana da kyau a zama da cikakken da aikinsu. Daga hanyoyin da ake nuna, al'adun da ake samun da cikakken da aikinsu, kofin kasa da gini da ke 50cm ana da 1.5mm, da kuma kofin kasa da gini da ke 50cm ko da zuwa ana da 3mm. Zabin holes da za a yi don cables yana taimaka wajen cikakken da aikinsu. Holes da ake bayar da suka ba daidai da abubuwan da ake bukata. Idan an yi entry da surface conduit, ita ce da za a yi da cikakken da aikinsu, kuma za a amfani da locknuts. Holes da za a yi don wires zana da kyau a zama smooth da kuma burr-free; metal panels zana da kyau a zama da insulating bushings. Muhimman abu, ita ce da za a yi connections da cikakken da aikinsu da ma'adanci.
Zabiyan Colours Da Wires Daga Hanyoyin Da Ake Nuna. Don three-phase four-wire systems da ake amfani da su a cikin kofin kasa, colours da wires suke da suka nuna: Phase A - Yellow, Phase B - Green, Phase C - Red, Neutral wire - Light Blue, Protective Earth wire - Yellow/Green bi-color. Ba a iya amfani da Yellow/Green bi-color wire don abu ba da sabon da ake nuna ba.
Yi Wiring Da Cikakken Da Aikinsu, Da Kuma Zaba Bundles Da Cikakken. Idan an yi wiring don incoming/outgoing wires da internal wiring a cikin kofin kasa, mutane masu aiki suna da kyau a yi aiki da cikakken da aikinsu. Wiring connecting electrical components a cikin kofin kasa yana da kyau a zama horizontal, vertical, neat, da kuma da ma'adanci. Straight sections da wires suka da kyau a zama smooth da straight; bending radius da curves ko corners ana da kyau a zama da 6 times da outer diameter da wire. Grouped connections da wire slack suna da kyau a zama neatly tied into bundles.
Yi Connections Da Wires Da Cikakken Da Aikinsu, Da Kuma Zaba Secure Neutral Da Earth Terminals. Daga hanyoyin da ake nuna, connections da wires da component terminals ana da kyau a zama da spring washers da kuma a zama da cikakken da aikinsu. Idan earth connections a cikin kofin kasa suka da cikakken da aikinsu, ba a iya amfani da aikinsu ba. Duk connections da wires (input, output, internal) ana da kyau a zama precise, firm, da kuma secure against loosening. Creepage distances da conductors ana da kyau a zama da standards. Stripping length da insulation ana da kyau a zama appropriate, da kuma core wire ba a iya zama exposed ba. Connections da multiple wires ana da kyau a zama crimped tightly, then tinned, da kuma receive a secondary insulation treatment compliant with standards. Additionally, kofin kasa ana da kyau a zama da complete neutral terminal blocks. Both box body da door (if it contains electrical devices) ana da kyau a zama da secure and reliable protective earth terminals.
Maintaining Cleanliness Inside and Outside the Box, and Clearly Marking Labels. Bayan aikin ta zama, mutane masu aiki suna da kyau a cire debris ko foreign objects daga inside da outside kofin kasa, don in zama clean. Then, clearly label the purpose da identification number da each meter, switch, fuse, da electrical circuit a surface of the distribution box.
