David,
We are adding circuits for power amplifiers at one of the local EOC:
Our electrician recommended that we pull both phases, neutral and
ground to each location, regardless if the device needed a neutral.
This would allow flexibility should we install new equipment. The
cost of the wire is negligible for the added flexibility it brings.
Two other recommendations:
* To oversize the wire by at least one gauge size (on a 20 amp
circuit, use #10 wire instead of the #12) to address potential
voltage drop issues.
* Use twist-lock or IEC 309 pin and sleeves, instead of straight
blade connectors.
