How does ambient temperature affect conductor ampacity and how is this accounted for in EVSE design?

• A. Lower ambient temperatures reduce ampacity; NEC provides adjustment factors.
• B. Higher ambient temperatures reduce ampacity; NEC provides adjustment factors; select conductors with adequate insulation and rating.
• C. Ambient temperature has no effect on ampacity; only conductor length matters.
• D. Ampacity depends solely on conductor gauge, not temperature.

Answer: (B)
