IEE ကေျပာတဲ႔ CPC
phase conductor ဟာ 16 mm2 နဲ႕ 16 mm2 ထက္ေသးေနရင္ cpc က phae wire နဲ႕အရြယ္တူရမယ္။
16mm2 ကေန 35 mm2 ထိဆိုရင္ cpc က 16mm2 ျဖစ္ရမယ။
35mm2 အထက္ဆိုရင္ cpc က phase wire ရဲ႔ထက္ဝက္ရွိရမယ္။။
cpc ဆိုတာက circuit protective conductor ပါ
equipment ေတြရဲ႕ body (Frame)ေတြနဲ႕တြဲၿပီး ေျမျကီးထဲကို သြားျမွပ္ထားလို႕ earth ၿကိုးလို႕ေခၚႀကပါတယ္။electrical installation လုပ္ရင္ ၃ ျကိုးပါမယ္ line ရယ္ Neutral ရယ္ Cpc( earth) ရယ္ပါ။ ္
