These recommended wire gauge selection tables are based on the 2008 National Electrical Code (2008 NEC),
assume 140°F (60°C) rated wire, include a 25% safety factor, and define the amperage ratings at the listed
distances that result in 5% voltage drop due to wire resistance. Five percent is normally acceptable in low voltage
systems.
