Electrical Cable Size [cracked] -

#6 AWG: 2.4 ohms/1000 ft → R = 0.72 ohms → VD = 14.4V (12%) – still high.

Example: 50A load, 75°C terminals, 3 conductors in conduit, ambient 30°C. Table says #8 AWG (50A at 75°C) is borderline; #6 AWG (65A) provides margin. Never use raw table values directly. Apply all that apply: 3.1 Ambient Temperature Correction (NEC Table 310.15(B)(2)(a)) If ambient ≠ 30°C (86°F), multiply ampacity by factor. electrical cable size
