1. A modular spa control system comprising:
a first printed circuit board (PCB) comprising circuitry and electronic components forming a part of the modular spa control system;
a second PCB comprising circuitry and electronic components forming a different part of the modular spa control system;
a bus bar comprised of a conductive material and being secured to each of the first PCB and the second PCB to create an electrically conductive path along a length of the bus bar between the circuitry and electronic components of the first PCB and the circuitry and electronic components of the second PCB;
a second bus bar which is also comprised of a conductive material and is secured to each of the first PCB and the second PCB to create an electrically conductive path along a length of the second bus bar between the circuitry and electronic components of the first PCB and the circuitry and electronic components of the second PCB, wherein the bus bar is connected to a positive power terminal and the second bus bar is connected to ground;
each of the bus bar and the second bus bar comprising a plurality of fastener holes disposed in spaced relation along the length thereof for securing the bus bar and the second bus bar, respectively, to the PCB and for securing any electrical connectors to the bus bar;
a first set of nut and bolt fasteners, each comprising a nut and a bolt, secured through selected ones of the fastener holes in each of the bus bar and the second bus bar and also through corresponding fastener holes in the first or second PCB's;
a first ground lug secured to an end of the bus bar and a second ground lug secured to an end of the second bus bar;
a second set of nut and bolt fasteners, each comprising a nut and a bolt, securing the first and second ground lugs to respective ends of the bus bar and the second bus bar, with the bolts of each nut and bolt fastener in the second set of nut and bolt fasteners extending through the fastener holes closest to the end of each of the bus bar and the second bus bar;
wherein electrical power is supplied to each of the first PCB and the second PCB through the bus bar.
