An automatic transfer switch includes first and second inputs inputting first and second voltages; a first output outputting a start signal; a first timer timing a first time after the second voltage is available; a second timer delaying for up to a second time before outputting a transfer signal, the second time being reduced by the first time when the second voltage is available; a transfer mechanism selectively electrically connecting one of the inputs to a second output; and a circuit cooperating with the inputs and the transfer mechanism, causing the start signal to be output responsive to the voltages not being available, and causing the transfer mechanism to electrically connect the second input to the second output in response to the transfer signal.
