- What is THHN wire used for?
- THHN is a thermoplastic insulated conductor used mainly in conduit for branch circuits in dry locations, and in many wet locations when run inside conduit. It is not a cable assembly, so it carries one conductor and needs separate neutral and ground conductors.
- Is 12-AWG wire right for a 20-amp circuit?
- Yes. 12-AWG copper is the standard size for 20-amp branch circuits. For 15-amp circuits, 14-AWG is the usual choice.
- Stranded or solid: which should I pick?
- Stranded bends and pulls through conduit more easily, which helps on runs with several bends. Solid is stiffer but simpler to terminate and works well for short, straight runs.
- Does this roll include a ground wire?
- No. It is a single black conductor, so a separate ground conductor is needed for the circuit.
- Can I use it outdoors?
- THHN is rated for dry locations and for wet locations only when protected inside conduit. Do not run it exposed outdoors.
