额定功率,也就是有功功率的单位是kw;额定功率除以功率因数(一般是0.8)即为视在功率,单位是kVA;视在功率除以0.38后再除以根号3就是电流值。最简单的估算,视在功率乘以1.5,即得电流值。根据电流值,选择开关,开关的额定电流值一般是6A,10A,[link widoczny dla zalogowanych],16A,25A,32A,40A,50A,63A,[link widoczny dla zalogowanych],80A,100A,[link widoczny dla zalogowanych],125A,150A(或160A),180A,200A,225A,250A,315A等等。然后根据开关值选择导线。导线是查表知道的。The Court of Appeal pointed out that R and F's submission in the county court was of overt, conscious racism, and it was not prepared to find that there had been unconscious discrimination.The decisionThe Court of Appeal said that, unlike the ordinary civil claim where the judge decides, on the claimant's evidence only, whether the claimant has made out a case, in this case the judge had had the benefit of the whole of the evidence. Despite the school's failure to comply with the statutory requirements, the judge had been entitled to find on the basis of all the evidence that R and F had not proved racial discrimination.
