Customer Questions & Answers

Is this wire appropriate to use to come off a 200 AMP home breaker box to run to a detached garage with a 100 AMP breaker box?

Asked by: Wannbeelectrictian
No. I believe the maximum current carrying capacity of #4 wire is 60 amps thus a 100 amp service on this wire would be out of code. I believe you'll need #1 wire for a 100 amp service.

will 3- 4awg stranded thhn copper wires fit in a 1" pvc conduit?

Asked by: Ed
Yes, if using Rigid PVC Conduit, Schedule 40, it will fit. The conduit fill would only equal 28.65%, and the maximum allowable percentage of conduit fill is 40.0% 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.

Under specifications section it states WET LOCATION "YES" is ths correct. I noticed someone replied that it would not be suitable for underground cond

Asked by: mark
This product is also rated THWN-2 which means it is rated for wet locations as well as dry locations. It is not rated for direct burial and must be installed in conduit if underground. In fact, it must be installed in a raceway (which includes conduits) wherever it is installed. The above advice is based upon the current edition of the National Electric Code (NEC).
