<p>A single wire power conductor (22j) is connected through remote power switches (24j1,...24jn) to a plurality of loads (26j,..26jn). The power conductor (22) is sized such that its current-carrying capacity is less than the current required to simultaneously operate all the loads 26j1,...26jn) connected thereto. Logic means are provided for delivering a control signal to the remote power switches 24j1,...24jn) to selectively energize the appropriate loads. The logic means additionally includes means responding to excess current flow through the power conductor to schedule the control signals to prevent simultaneous operation of all the loads thereby limiting current flow through the power conductor to its current-carrying capacity.</p> |
