I am an Electrian and for each of my two systems I ran two dedicated 120V 20 amp isolated ground lines. Providing me with 80% of 40amps at each location. I use hospital grade isolated ground receptacles. I make my power cords with 12-3 SJ cord to minimal lenth using hubble connectors and they are all plugged into a power conditioner that in my opinion makes the most difference, for those that do not know isolated ground means that the ground is connected back at the panel and nowhere in between. This reduces interference from RF noise. The isolated ground and the power conditioner is all you need, IMHO, though others may differ. By the way I dont know of any Electrician that will run a dedicated line from your equipment to your panel for $200.
