Spent the day running power cables to the future radio room. A 2-conductor #4 AWG Teck cable from my renewable energy backup power system will handle all of my 12 volt DC requirements. On the AC side, the house has a natural gas range so I "borrowed" the feeder cable for the electric range receptacle in the kitchen and re-routed it over to the shack. It was just the right length and when I get a chance I will install a four-circuit breaker panel to power a 220V receptacle for the amplifiers and a couple of standard 120V receptacles for everything else.
So far, so good!
