Wiring for 230v table saw

Hi all,

I need to wire a new outlet for a table saw, and am getting conflicting advice on what I would need to do this. What wire and breaker should I be getting to support this job?

Here are the details
  • Running off a Sub-Panel
  • Saw Voltage: 230v
  • Saw HZ: 60hz
  • Saw Amp Draw: 13amps
  • Outlet will be 25' from fusebox

I forgot to mention that it needs a NEMA 6-15p receptacle.

Thanks
Steve

  • 12-2 NM-b if cable or black, white, green, THHN #12 if conduit.
  • 20 amp two pole breaker or two 20 amp fuses.
  • NEMA 6-20 receptacle.

Thanks ray2047! I totally forgot to mention that the saw currently requires a NEMA 6-15p receptacle (that's what's on the cord now). Does that change what you've advised?

Nope, a 6-20 has a "T" shaped slot that will accept either 15A or 20A plugs. You also should tape the white wire red to re-identify it as a hot conductor. If the cable is running through an area subject to damage, it needs to be protected by substantial wood framing, wallboard sheathing or sleeved in conduit. Generally the area under 8' high in a garage or shop is considered subject to damage.

13 amps is close to the limit for a 15 amp circuit so I factored in a bit of head room especially since it is a motor and there is a a very brief high amp start current. Plug on the saw is fine for 13 amps.
