Wire, overcurrent protection, and disconnect sizing and selection

High temperatures increase the resistance of the wire and reduce its current carrying capacity. Note: Wires, nor conduit, should be located less than 2.25 cm from a roof surface in direct sunlight. This will increase temperatures as much as 33°C and can lead to the ampacity and temperature rating of wires to be exceeded.
