Because the fuse was open, the employees als o (mistakenly) believed that the circuit to the transformer was deenergized. The y began working on the transformer as if it were deenergized even though they di d not check it for voltage and ground it. One of the employees put his hand on t he primary booster atop the transformer while his chest was touching the neutral
