10 AWG THHN/THWN-2 – The 30A Workhorse for Equipment and Appliance Circuits
Some equipment cannot run on a 20A circuit. Water heaters, commercial cooking equipment, and smaller HVAC units demand 30A circuits, and that means 10 AWG THHN/THWN-2 wire. This wire uses a pure copper conductor with PVC insulation and a nylon jacket, certified to UL83 with a 600V rating. The nylon jacket reduces friction during pulls and protects against installation damage. The THWN-2 rating supports damp location installations. Stranded construction improves flexibility for conduit bends. Solid construction works well for shorter, straighter runs. This gauge is the practical choice when 30A capacity is needed.

90C Copper THHN/THWN-2 Wire
FAQ

 

What breaker size is typically matched with 10 AWG?
A 30A breaker is standard. The 90°C insulation allows higher ampacity, but terminations typically limit it to 30A.
Is 10 AWG available with a green jacket?
Yes. Green 10 AWG is stocked for grounding applications.
How does 10 AWG behave in freezing temperatures?
The insulation remains workable in moderate cold. Below 20°F, allow the wire to warm before pulling to avoid jacket stress.
What is the preferred method for stripping 10 AWG THHN?
Use a wire stripper with a 10 AWG opening. Insert the wire fully, rotate, and pull. Inspect the conductor for nicks before terminating.
