[Amps] Dedicated 220AC Wiring for Amps..

[Bill Fuqua]

                 The minimum size wire specified in the "National 
Electrical Code" is chosen for voltage drop, and to make it easy for the 
electricians to make the right choice, in most cases,  and not for 
temperature rise.  I have had a problem with electricians insisting that a 
larger size wire is not allowed. And of coarse it is.  Some people function 
on simple sets of rules and just can't make decisions based voltage drop, 
wire size and length.  So the code accommodates these people who are 
hopefully not the licensed electricians but their helpers.

         I ran #6 to my amplifier off an 20 amp 240 volt breaker. It is a 
fairly short run but it did solve my voltage drop problem.  I am 
considering adding a filtering choke to my power supply. At a full 240 
volts it produces much higher voltage my 4-1000A amplifier needs. This 
naturally, doing this  would eliminate the need for the larger wire but 
would add weight to the power supply.  The upside is that the load 
regulation would improve.
