WIRE / CABLE — AMPACITY DEPENDS ON INSTALLATION CROSS-SECTION JACKET WIRE SPECIFICATIONS Conductor Size: — Conductor Count: — Voltage Rating: — Insulation: — Temp Rating: — PN: 8-5159 · OEM ⚠ 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 PARTSTABLE TECHNICAL DRAWING — NOT TO SCALE
