Longer AC power feeds need to be properly designed to preserve voltage levels to the equipment. The wiring from the breaker panel to the power strip, which supplies power to the storage appliance and disk shelves, can often exceed 50 feet.
Note
Total AC wire length = breaker to wall or ceiling outlet + extension cable or ceiling drop.
The following table lists the recommended conductor size for 2% voltage drop for a particular distance in feet (taken from the Radio Engineer's Handbook).
The following table list the approximate equivalent wire gauge (American Wire Gauge (AWG) to Harmonized Cordage).
1 mm-mm = millimeter squared
