A data center includes electrical loads and an electrical power distribution system. The electrical power system includes a primary power source, one or more secondary power sources, and one or more groups of automatic transfer switches. Each automatic transfer switch and its corresponding load define a branch of the group. Each of the groups of automatic transfer switches includes a power cross-coupling system that cross-couple the branches in the group such that a load coupled to the output of the automatic transfer switch in one branch in the group is coupled to the output of an automatic transfer switches in the other branches of the group.
