Refer to additional circuit breaker notes in 3.2.7 - Accessory Fuses and Backfeed Breaker
Wiring.
NOTE
The breakers and cables used must be in accordance with NEC ANSI/NFPA 70. A disconnect
breaker must be provided for AC input, DC input and AC output. Recommended cable sizes are
suitable for operation at a maximum temperature of 86°F (30°C). For continuous operation at
temperatures above 86°F (30°C), the site design should include cables that meet requirements
for 104°F (40°C) installations.
