The ATS connects utility power and generator power to critical loads. Its rating, pole configuration and control signals must match the site design.
Generator start signals, battery chargers, heaters and remote alarms should be checked before automatic testing.
A complete test includes utility failure simulation, generator start, transfer, load running, retransfer and cooldown.
