This can only happen if everything in between phases of conductivity is bone dry. This includes being cleaned with an absorbent material like paper towels. Before connecting anything back up again! 

A hairdryer will suffice for small generator-sized units. But larger Gensets require something more powerful. Such as blowers capable enough to blow around 200 degrees Fahrenheit.
