Questions & Answers
What is the outer diameter?
0.0403 in.
The correct answer is not 0.0403 in. That is the size of the bare wire itself, also known as 18 gauge or AWG. My question referred to the product itself. So I went back to Home Depot and bought a small piece. Fits snugly in a 5/16" hole in my drill gauge.
Do I need to run the wire through conduit from the eaves to my sprinkler valve box? The spinkler valves are by the house. So I won't be burrying an cable.
We are happy to help! For assistance regarding your question, please consult with our experts at CableTechSupport@southwire.com
how much does a 500 foot roll of 18/7 weigh?
It should be around 23 lbs.
Is the seven individual wires stranded or single copper? The sprinkler wire I am replacing is single copper. Thanks
We are happy to help! Please consult with our team at cabletechsupport@southwire.com for further assistance.
Thanks for your question. The 7 wires in the cable are solid copper, not stranded.
Can two 18/7 100 ft sprinkler wire be spliced together? I don't need 500 ft.
Yes
Yes they can. Home depot sells various waterproof wire connectors: https://www.homedepot.com/p/DryConn-GTSR-Direct-Bury-Grease-Tube-with-Strain-Relief-with-Yellow-Nut-Wire-Connector-25-Pack-per-Bag-20210/205346937 https://www.homedepot.com/p/DryConn-Waterproof-Wire-Connectors-Assortment-Small-and-Medium-20-Pack-62024/204738279 https://www.homedepot.com/p/Brown-Waterproof-Wire-Connector-10-Pack-BLS10/305324978 But if you can, it would be better and less expensive to solder the wires together to join the 2 lengths. Be sure to use heat-shrink tubing around the exposed wires to avoid moisture contamination (don't forget to run the pre-shrunk tubing before you join the wires.) You could bury the cable and have less of a bulky junction as well.
Of course, use silicon dielectric grease/sealant inside wire nuts after twisting connections together. Or pay the extra buck and buy the specialty wire nuts. Probably you should add a ICV box to reference splice point in ground for future diagnosis. Not mandatory, but in commercial irrigation, we spliced in cut wires all the time and it was always helpful to throw a box on top of fix in case long-term oxidation reduces voltage going into 24vac solenoids. Sometimes a hassle to track down and diagnose.
The typical irrigation controller controls 6 solenoids plus a master solenoid. So why cant I buy an 8 wire cable?
You can, but not with Home Depot
Please consult an 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.
Yeah that sucks. You need that common/ground wire, but you could run a single copper wire separately, even a bare one as long as the other leads aren't exposed and save a lot of money. I had a 5 lead wire and wanted to increase from 3 to 5 solenoids. It did the trick.
Thanks for your question. Home Depot does sell an 18 gauge 10 conductor direct burial cable (also Southwire brand), by the foot, on the Home Depot web site only (as of 10/2/2020).
I only needed five wires for my initial hookup. If I ever add an area, I am ready to go. The extra wires are great
What colours of the wires are on the inside
The colors really don't matter as long as you match them up to the right sprinkler systems.
Blue, black, yellow, orange, green, red, white. The above advice is based upon the current edition of the National Electric Code (NEC).

The colors are white, blue, green, brown, black, red and yellow.
Is the 50 foot 7 conductor sprinkler wire color coded? Do you carry a 9 OR 20 conductor wire?
Works as described
Cast of the first one no to the second one
Yes the wires are color coded. Each of the wires is a different color.
While I do not know what conductor numbers they carry I do know that this sprinkler wire is color coded Red, Green, Black, Yellow, Blue, White, And Brown.
Yes, its color coded. I'm not authorized to provide the web link. I'd recommend going to HD's website for different conductors.
