The electrical wiring necessary to keep the computer isolated from most types of electrical interference would be a dedicated circuit. In other words, a circuit that has its own circuit breaker at the main junction box, and no other appliances (other than computer devices) connected to that same circuit. This would generally involve having only the electrical outlets connected to this line located near the computer. This way the computer and related equipment would be the only things plugged into this circuit, thus helping to isolate electrical noise sources. Although this method is very beneficial and is recommended, it cannot completely eliminate all problems that could arise. This type of wiring setup is also known as "computer grade power" and "isolated ground" wiring.
