The present invention relates to a power distribution panel in which a plurality of loads is connected to an incoming power source. In one embodiment the strap is extended to opposed corner areas where opposed end portions of the strap are fastened to a portion of the upper or lower member and to a portion of an adjacent column or stud. The peg is moved after the satisfaction of each time within the schedule. A second bidirectional switch discharges energy from the load during off phases of the first bidirectional switch. The actuator is located radially within an envelope of the tube. In addition, a plurality of couplers andor coupling members may be used to couple conduit with small diameters and conduit with large diameters.
