Questions and Answers for Southwire (By-the-Foot) 2 White Stranded CU SIMpull THHN Wire

A:  Please contact a local electrician. The above advice is based upon the current edition of the National Electric Code (NEC). Free access to the latest version of the NEC is available online at www.nfpa.org/freeaccess. The NEC and local building codes regulate the types of wire and cable that can be used in specific electrical applications, as well as the manner of installation. Check your local building codes before you start any wiring and cable electrical project and be sure to obtain required permits. When your work is complete, always have it inspected for compliance with local codes to ensure that it has been safely installed.

A:  I suppose that it could be, however due to size of the individual strands of copper in the cable it is not very flexible. Cable made specifically for welding is made from many more smaller strands.

A:  Yes. You have to run three wires of this between the panels and a green wire for a total of four.

A:  Only if the lug temperature rating also is rated for 90 degrees c. #2 THHN is rated @130 amps @ 90 degrees c. If max lug temp is 75 degrees c. the amp rating would need to be derated to 115 amps to match the maximum lug temperature rating or upgrade to #1 wire.

A:  I'm not aware of any section of the NEC prohibiting the instillation of THHN into EMT in residential applications. Could you reference the code section?

A:  No, 2/0 is the 'same' as 00 wire. This is #2AWG. 2/0 is much larger (in diameter) than #2 and therefore is used for much larger applications requiring much higher load (ampacity) rating. Please note that working with loads requiring either wire size is extremely dangerous (lethal). Examples per use, #2AWG could be used to wire a smaller sub-panel whereas 2/0 wire could be used in a main service panel. You can look up the ampacity rating for the wires online to determine which size wire is appropriate for the application.

A:  No, this is not the same as 2/0 copper wire.

A:  This wire weighs approximately 12.02 lbs

A:  This roll weighs approximately 117 lbs.

A:  No. THHN cannot be used in residential applications. It can only used cable tray or conduit in commercial and industrial applications.

A:  Pretty sure a raceway must be used.

A:  No. THHN is not rated for direct burial. The above advice is based upon the current edition of the National Electric Code (NEC).
