Clarus Duet Power Conditioner

The electrical code for house wiring requires a certain wire size for specific types of circuits. The most common 15 amp circuit requires 14 gauge wires. Higher current circuits require heavier gauges. It’s acceptable to wire a circuit with a heavier gauge than code requires. It is against code to start at the power source with one size wire and then at some point in the circuit increase the wire size. The larger wire will handle more current and could overload the smaller wire resulting in a potential fire hazard. The reverse is, however, acceptable. In other words going from a larger to a smaller gauge is acceptable as long as the smaller gauge meets code. And yet, how many audiophiles use standard 15 amp / 14 gauge circuits and then connect heavy gauge aftermarket power cords. To address this in my own system I installed five dedicated circuits, three with 6 gauge, and two with 10 gauge wire, as well as using high quality duplex outlets. My understanding is that larger wire gauges better reject EMI / RFI interference. I also use two ground rods dedicated to my sound equipment and isolated from house ground.
