An electrical power delivery system and method of operation particularly suitable for use in a vehicle is disclosed. A single wire power conductor is connected through remote power switches to a plurality of loads. The power conductor is sized such that its current-carrying capacity is less than the current required to simultaneously operate all the loads connected thereto. Logic means are provided for delivering a control signal to the remote power switches 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.
