Questions & Answers
Can this be used outside for lighting?
Asked by Tyler December 24, 2018only if you use it in conduit rated for exterior and don't forget the waterproof connections at each end and joint
How long in "meters" contains this roll?
Asked by Pippo September 9, 2019Approximately 152.4 meters. 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.

I have a 75' run for a stereo speaker - can I use this for speaker wire?
Asked by NotHandyAndy July 18, 2018no, for the speakers you must use "speaker wires " and depending on the distance and the impedence of them is the gauge you are going to use. I recommend de wire speaker no.12.
Can I use this wire for landscape lighting? Also is it waterproof?
Asked by AJ August 29, 2017No, this wire is not for direct burial. Most newer landscape lighting uses 12 volt low voltage for landscape lighting. It's fed by a transformer that reduces the 120 VAC line voltage to 12 volts which is safer. You can directly bury the cable that is compatible with that lighting system. The main thing is to make sure no gardener or person digs around it as it can be damaged with spades and such.
I'm adding more plugs to my home. Will this work for which items and color?
Asked by Lizzie January 3, 2018Only if you have conduit to install your conductors in. Romex (non-metallic sheathed cable) comes with everything you need in most situations residential. If your residential dwelling is over 3 floors, you will probably need BX (armored cable)
is this wire rated to be pulled through underground conduit
Asked by dennis August 6, 2017no
THHN is NOT for use in buried conduit. Moisture condenses in the conduit, and the wire must be "...
Asked by SparkyMan May 31, 2018All southwire THHN is also rated THWN-2, THWN, TWN75, MTW, and AMW. Cerrowire is the same except TWN75 Check the "product brochure" in the info and guides section above.
Is this item available for "In Store Pickup" ?
Asked by Thomas May 1, 2015It's in inventory in different colors and sizes mostly, but most stores don't keep much backup stock and electricians go to the store after hours or in a hurry to get this wire for jobs. Pricing is retail and most contractors buy at wholesale for their jobs.
How heavy is the 500 ft.roll and is the wire ideally suited for wiring my house
Asked by Shortest March 7, 2016About 15 pounds, and you have to install THHN in conduit as it's just one conductor. In single outlets you need 3 THHN in conduit (White, Green, and a color like Red or Black). By far conduit installed in your house is a better idea that also allows for wiring changes or upgrades later. It's just more expensive. This is the way commercial wiring is installed in buildings.
