Hi, happy to help! “Non‑metallic” refers to the outer jacket and sheath, not the conductors inside. Romex SIMpull NM‑B has copper conductors—the “non‑metallic” part simply means the outer sheath is plastic (PVC) instead of metal like MC cable. So yes, your 10/3 Romex SIMpull is 100% copper wire inside. If we can help in any other way, please reach out to us at consumersupport@southwire.com.
