Kedu ihe bụ asambodo CB?

IECEE CB bụ ezigbo usoro mba ụwa nke izizi maka nnabata ọnụ maka akụkọ nchekwa nchekwa akụrụngwa eletrik. NCB (National Asambodo Body) ruru a multilateral nkwekọrịta, nke na-enyere ndị na-emepụta aka inweta asambodo mba site na mba ndị ọzọ so n'okpuru atụmatụ CB ndabere na-ebufe otu n'ime NCB asambodo.

Asambodo CB bụ akwụkwọ atụmatụ CB nke NCB nyere ikike, nke bụ ịgwa NCB ndị ọzọ na ihe nlele ngwaahịa a nwalere kwekọrọ n'ụkpụrụ ọkọlọtọ chọrọ.
