I needed the help of electricians but I am no DIY type. A dedicated line is an electrical circuit that is used by your audio equipment only. The Idea is to ensure that no other outlets or appliances share that line.
If you want to upgrade it to 20 amps it would be wise to do it while installing your dedicated lines.
