SKU CH-YE52-78TFN

Bare copper grounding wire, 6 AWG stranded, 315 ft spool rated 600 V AC and 167 °F with 0.18 in diameter

  • TypeWire & Cable
  • 315-foot spool reduces splice points on long grounding runs
  • Stranded 7-wire construction bends easily around corners and through conduit
  • 6 AWG copper meets 600 V AC rating for residential and commercial grounding
  • 167 °F temperature rating withstands heat in utility and panel environments
  • Bare copper surface ensures direct, low-resistance contact with grounding electrodes

Grounding wire for electrical systems

Southwire 10665803 is a bare copper grounding conductor supplied on a 315 ft spool. The 6 AWG stranded design uses seven strands to meet ASTM standards for grounding and bonding applications. It is rated for 600V AC service and a maximum temperature of 167 degrees F.

Voltage and temperature limits define use

The 600V AC rating restricts this wire to circuits operating at or below that potential. The 167 degree F temperature ceiling means it cannot be used in environments or conduit fills where insulation temperatures would exceed that value. These two figures set the practical boundaries for code-compliant installation.

Stranded copper on a spool aids handling

Seven-strand construction keeps the 0.18 in diameter conductor flexible for pulling through raceways and bending around terminals. The bare finish requires no stripping, so connections are made directly to the copper. Spool packaging keeps the 315 ft length tangle-free during transport and on-site dispensing.

Questions about this item

Should I choose the 315 ft spool or a shorter length for a residential grounding job?

The 315 ft spool suits whole-house grounding runs and multiple electrode connections; buy a shorter coil only if the total trench and panel distance is well under that figure.

What does the 600V AC rating mean when this wire is installed in a service panel?

It confirms the insulation-free copper is approved for circuits up to 600 volts alternating current, covering standard residential and light-commercial panels.

Does the ASTM listing and 7-strand construction affect how the .18 in diameter wire terminates in a lug?

The 7-strand ASTM construction keeps the .18 in diameter flexible enough to seat cleanly in standard 6 AWG lugs without fraying or over-tightening.
