Abstract
An automatic transfer switch (ATS) for supplying power to a load is provided. The ATS includes a main transfer switch portion configured to connect one of a first or second power source to the load. The ATS also includes a bypass transfer switch portion configured to form a bypass connection from either the first or second power source to the load. The bypass transfer switch portion includes (i) a first bypass switch configured to connect the first power source to the load upon closing of the first bypass switch and (ii) a second bypass switch configured to connect the second power source to the load upon closing of the second bypass switch. Further, the ATS includes a primary load connection connecting the main transfer switch portion to the load, where the primary load connection is formed at least in part by the first and second bypass switches.
