Abstract: A connector having enhanced protection against arcing during live or “hot” connection of a plug assembly to a receptacle assembly. The terminals of the connector, including the connection point of exposed wiring, are electrically isolated from each other with dielectric barriers built in to the connector, such as polymer partitions. Accordingly, protection against arcing is provided in a connector that is assembled fast and inexpensively, without need for a time consuming installation of wire and terminal coatings or sleeves (e.g., “shrink tube”), and with greater reliability. The connector can be used in a modular system for decorative lighting and having a controller module that is not hard wired to a light string. Use of the controller module independent of any of the light strings enables the controller to be used with any light string or with a replacement light string, in the event that the immediately connected light string fails.
