    Feeding 250 amp 3 phase board direct from buzz bar need isolatir

    I'm usually doing domestic work but now work for a new employer. He's gave me a 100 amp isolator to feed from the bus bar to then feed the dist-board,my boss has supplied all the materials. So if the dis-board main switch was 100amp I could connect tails direct to busbar? Thx guys
