Abstract
The invention is a method for intelligent current limiting enabling chaining of electrical appliances. Different embodiments apply to alternating current (AC) appliances, direct current (DC) appliances, and a combination of each. In each embodiment, current limits control the number of appliances that can be connected in the chain. If current limits are exceeded, current-limiting devices cut power to one or more of the appliances. Each appliance in the system has conductors with the capacity to carry a current load at least as large as the overall current limit. Preferably, the appliances in the system are garage appliances that are mounted to an overhead track system in a garage, where electrical outlets are scarce.
