czarivey....No u are wrong. My cdp is not on a dedicated line. So i will be adding a dedicated line for that. But i already bought a Furutech GTX-d r 20 amp. At first i thought i could use it for my non dedicated 15a line with my Furutech GTX-d r . But not according to Elizabeth if i am reading her answer right. But since i want to have a dedicated line for my cdp i might as well go with a 20a dedicated line so i can use my 20 a Furutech with my cdp. Does this make sense?
