Both are copper conductors, but they’re built differently and used in different ways.

• Solid copper: One single conductor. It holds its shape, can be easier to push through straight runs, and is commonly used in fixed indoor wiring and some control lines.
• Stranded copper: Multiple finer strands. It’s more flexible for tight bends and movable equipment, and is common in audio/low-voltage and automotive applications.

Both types come in various gauges (AWG) and ratings (e.g., NM‑B, THHN/THWN, CL2/CL3). Check each product page for “solid copper” or “stranded copper,” gauge, voltage rating, and location suitability to match your project.

You can browse and buy online, then choose delivery or store pickup where available.

• Search smart: Use terms like “solid copper,” plus the gauge (e.g., 12 AWG, 14 AWG) and type (NM‑B, THHN, thermostat, ground).
• Verify details: Open the product page and confirm conductor material, conductor type (solid), gauge, voltage rating (often up to 600V), and indoor/outdoor notes.
• Pick a length: Select the spool size that fits your project to minimize waste.
• Checkout options: Choose Shipping or Pickup & Delivery if shown for your area.

Review specs and certifications (e.g., UL, ETL) so the wire aligns with your application.

Several factors can influence what you’ll pay for solid copper wire.

• Gauge and conductor count: Lower AWG (thicker) and more conductors (e.g., 12/3 vs 12/2) typically cost more.
• Length: Longer spools raise total price but may lower cost per foot.
• Construction and ratings: Indoor NM‑B, armored MC, direct‑burial/UV‑resistant jackets, and certifications can affect pricing.
• Copper content: Pure copper generally costs more than copper‑clad alternatives.
• Market conditions: Copper commodity trends can impact retail prices.

For value comparisons, check each product page’s specifications and, when available, compare cost per foot for similar gauge, rating, and length.

Rely on the listed specifications rather than color or feel.

• Terminology: Look for “solid bare copper,” “pure copper,” or “OFC (oxygen‑free copper).” “CCA” indicates copper‑clad aluminum, not pure copper.
• Spec fields: Review conductor material, conductor type (solid/stranded), gauge (AWG), and rating (e.g., NM‑B, THHN/THWN, CL2/CL3) on the product page.
• Certifications: Listings such as UL or ETL on building wire can provide added confidence in stated materials and ratings.

If you need certainty, choose a listing that explicitly states “solid bare copper” or “100% copper” in the conductor material field.

Outdoor suitability depends on the cable’s rating, not just the conductor.

• Outdoor/direct burial: Irrigation/sprinkler control wire and cables labeled “direct burial” or “UV‑resistant” are intended for soil and sun exposure.
• Wet locations: THWN or THWN‑2 conductors are designed for wet environments when installed in appropriate conduit.
• Indoor only: NM‑B building cable is intended for dry, indoor locations.

Match the cable’s rating to your environment and follow local codes. For installation specifics or code questions, consider consulting a licensed electrician to review your exact setup.
