What happens if a cable is buried?
Can SOOW cable be used outside?
Are direct burial cables safe?
Can a cable be buried underground?
Let’s talk about SOW cable, shall we? This type of cable is commonly used for outdoor applications and you might wonder, “Can I bury it?” Well, the answer is a bit more nuanced than a simple yes or no.
SOW Cable stands for Service-Over-Wires, and it’s specifically designed to handle the demands of outdoor wiring. It’s typically used for things like:
Connecting power to homes and businesses
Powering outdoor lighting and appliances
Running power to sheds, garages, and other structures
But there are different types of SOW cables, and not all of them are suitable for direct burial. So, how can you tell if your SOW cable is up for the job?
Let’s break it down.
Understanding SOW Cable Types
SOW cables come in various forms, and each type has different characteristics:
SOW-A Cable: This cable has a black outer jacket and is designed for direct burial.
SOW-B Cable: This cable has a white outer jacket and is designed for above-ground installation only. It’s not meant for direct burial.
SOW-T Cable: This cable has a tan outer jacket and is a newer type designed for both above-ground and underground installations.
The key to determining if you can bury your SOW cable is looking at the color of the jacket. It’s a simple visual cue that can save you a lot of trouble!
Why Does It Matter?
You might be thinking, “What’s the big deal? Can’t I just bury any cable?” Well, the answer is absolutely not. Direct burial cables have specific properties to withstand the harsh conditions underground.
Moisture Resistance: Direct burial cables need to be resistant to moisture. The earth can be surprisingly damp, and this can damage the insulation of a regular cable, leading to short circuits and other problems.
UV Resistance: Sunlight can degrade the insulation of cables over time. Direct burial cables are made with materials that resist UV damage, preventing them from deteriorating prematurely.
Toughness: Direct burial cables need to be tough enough to withstand the pressure of the surrounding soil. They are often reinforced with additional layers of insulation to protect the wires.
Things to Consider Before Burying SOW Cable
Before you start digging a trench and burying your SOW cable, there are a few important considerations:
1. Local Building Codes: Every city and county has its own set of building codes. These codes specify the types of cables that are permitted for direct burial, and how they must be installed. It’s crucial to familiarize yourself with your local building codes before you start any project.
2. Depth: The minimum depth for burying SOW cable is 18 inches. This provides adequate protection from damage and ensures that the cable isn’t exposed to freezing temperatures.
3. Trench Width: The trench needs to be wide enough to accommodate the cable and any protective conduit or wrapping you plan to use.
4. Marking: Once the cable is buried, you need to mark the location of the cable so that it doesn’t get damaged by excavation work in the future.
5. Electrical Safety: Always work with electricity safely. Make sure the power is off before you start any work on the wiring, and wear appropriate safety gear.
Is There an Alternative to Burying SOW Cable?
If you’re not sure about direct burial, or if your local codes don’t allow it, there are alternative methods for installing SOW cable.
Above-ground: You can run SOW cable above ground using conduit or other protective methods. This can be a suitable option if you don’t want to dig a trench, or if your local codes require it.
Underground conduit: If you need to run the cable underground but aren’t comfortable with direct burial, you can use conduit. This involves running the cable through a protective pipe or tubing. This approach provides added protection from moisture and damage.
FAQs
Q: What if I’m not sure if my SOW cable is the right type?
A: If you’re uncertain, it’s best to contact a qualified electrician for assistance. They can help determine the appropriate cable type for your situation.
