A control system for a whirlpool bath installation, including a single input source wiring for connecting to an input source of high voltage AC electrical power having a nominal current rating. A plurality of high voltage output connections are connected to the input source through a corresponding plurality of switches, for power connections to a respective high voltage load devices, whose cumulative nominal current draw ratings exceeds the current rating of the input source. An electronic controller controls states of the switches in response to user input commands. The electronic controller implements an algorithm or a set of rules preventing a system utilization of the high voltage loads from exceeding a total current draw exceeding said nominal maximum current rating.

A multiple coaxial connector includes a contact pair that is composed of a first contact and a second contact, a body that accommodates each contact, a shell that accommodates the body, a shield cover that covers a portion of the shell, and a board mounting portion. The first contact includes a first main body portion that is extended in a first direction, a first contact portion that is formed on one end of the first main body portion and is to be brought into contact with a contact of the mating multiple coaxial connector, and a first leading portion that is extended from the other end of the first main body portion in a direction that is orthogonal to the first direction and directs toward a second direction. A plurality of the contact pairs are arranged in a third direction.

A power distribution unit (PDU) comprises a housing, an input on the housing, and an input connector coupled to the input on the housing. The input connector is connectable to a power source that provides power for distribution by the PDU to one or more power consuming devices. The PDU includes an output including output connectors that provide blind-mate connection with a connection interface coupled to the one or more power consuming devices.

A bus bar assembly comprises a first bus bar and a second bus bar. Each bus bar comprises a bridge flange having a first side and a second side, top and bottom flanges extending from the first side of the bridge flange, and an interface flange extending from the second side of the bridge flange. The bus bar assembly further comprises a first insulation layer positioned between the top flanges of the first and second bus bars and a second insulation layer positioned between the bottom flanges of the first and second bus bars. Each of the top and bottom flanges comprises a plurality of mating devices coupled thereto. The top flanges of the first and second bus bars and the first insulation layer are fixedly joined together. The bottom flanges of the first and second bus bars and the second insulation layer are fixedly joined together.
