Lifting the grounds means to use the "cheater" plug which in a three prong to two prong adaptor.
To continue a bit more....Stehno, you say, "or installing an isolated ground for these dedicated lines..." how about this situation. I have two wire service in my house. I was able to add a 20 amp three wire line for the stereo. There also is a 15 amp two wire line already there. Can I run a ground "jumper" to the two wire line? Would this help eliminate ground loops??
