⚠ VERIFY BEFORE ORDERING
Ampacity depends on installation method — conduit ≠ free air ≠ underground. Same wire, different ratings.
AWG sizing is inverse — smaller number = thicker wire (4 AWG > 12 AWG)
✓ BROKER TIP
Stranded = flexible routing and vibration resistance. Solid = fixed conduit runs only.
THHN/THWN = dual rated — check both dry and wet ampacity tables
