SOUTHWIRE COMPANY

SOUTHWIRE COMPANY 11595617 THHN 10 AWG Black 50 ft

SKU CH-SE5A-QPHBT

Solid 10 AWG THHN building wire with PVC insulation and nylon jacket, rated 600 V AC, supplied on a 50 ft spool

  • Product typeSolid
  • Solid 10 AWG conductor fits tight conduit bends
  • 50 ft spool covers typical branch-circuit runs
  • THHN nylon jacket resists oil and gasoline exposure
  • 600 V rating suits residential and commercial wiring
  • Black insulation identifies hot leg in standard colour code

Application & Rating

This 10 AWG THHN building wire is rated for 600V AC and suits conduit or raceway installations in residential and commercial projects. The solid copper conductor with PVC insulation and nylon jacket meets standard code requirements for branch circuits. Supplied on a 50 ft spool for convenient pulls.

Who It Suits

Electricians and DIYers running single-conductor feeds in dry locations will find the solid construction easy to terminate. Buyers needing flexible stranded wire for vibration-prone or tight-radius routing should consider a different conductor type. Not intended for direct burial or wet locations without additional protection.

Critical Spec

The nominal outside diameter of .15 in determines conduit fill calculations and pulling tension for this 10 AWG solid conductor. Verify raceway capacity against this dimension before specifying the wire for your installation.

Questions about this item

How do I install the 10 AWG solid THHN wire into a breaker panel, and what is the common mistake?

Strip the PVC insulation carefully, avoid nicking the solid copper conductor, and fully seat it under the terminal screw; the frequent error is leaving a loose connection that overheats.

What maintenance or replacement will the nylon-jacketed THHN wire need over time?

Inspect the 0.15 in. diameter jacket periodically for cracks, cuts, or chemical damage; replace any length where the nylon or PVC insulation is compromised.

What limit appears first when the 600 V wire runs at full load continuously?

The 10 AWG solid conductor reaches its ampacity ceiling first; sustained current at that level maximises allowable temperature rise within the 50 ft spool length.
