Daniel A. Andrus, licensed Master Electrician and former fire fighter, had always been fascinated by light, heat and power, and the many ways an electrician is able to keep businesses productive. In 1993, just three years after founding his electrical contracting company, Andrus began developing extraordinary expertise in a group of products that can not only maintain a businessÂ?s functionality, but contribute to its success. These products are alternative, emergency and stand-by power systems Â? or generators.
