If using a dedicated line I found out 2 things from a Audiophile electrician silver 20 amp contacts can be ordered as well as 40
industrial , and use 4 wire awg 10 that is what I have 2 grounds,one common ,the other a insulated isolated ground.
and outlets heavy duty copper, gold plated outlets I found the Pangea outlets at $50 each a true bargain ,
and Puritan makes a much better line conditioner then most ,Audio archon sells them ,night and day better then this plain Torroidal type so called line conditioners ,I had the top 1800 ultra
from Underwood the AQniagra 3000 much better ,and the Puritan
much better still but more $$ also .
