Lost Power to Your Home or Outdoor Shed? Underground Electrical Wiring Could Be the Problem

A sudden loss of power to part of your home or an outdoor building can be frustrating, especially when the cause isn’t immediately obvious. While tripped breakers and faulty outlets are common electrical problems, sometimes the issue is hidden underground.

At Waldrop Plumbing, Air & Electric, our electricians help homeowners throughout Greenville, Spartanburg, Anderson, and Upstate South Carolina diagnose and repair electrical problems, including damaged underground wiring.

Recently, one of our electricians responded to a service call involving a power outage affecting both a home’s living room and an outdoor shed. What initially appeared to be a simple electrical issue turned out to be damaged underground wiring caused by nearby construction.

What Causes Underground Electrical Wiring to Fail?

Underground electrical wiring can become damaged for several reasons, including:

• Excavation and trenching: Equipment used to install utilities, fiber optic cables, or drainage systems can accidentally strike buried electrical lines.
• Ground movement: Shifting soil and settling can place stress on underground electrical connections.
• Moisture intrusion: Water entering improperly protected wiring or connections can cause corrosion and electrical failures.
• Aging electrical systems: Older wiring and deteriorating insulation may become more vulnerable to damage over time.

In this particular service call, our electrician discovered that a trenching machine used during a fiber optic installation had damaged the underground electrical wiring supplying the outdoor shed.

How Our Electrician Diagnosed the Power Outage

When our electrician arrived, the homeowner was experiencing a loss of power in both the living room and outdoor shed.

After troubleshooting the affected circuit, our electrician identified damage to the underground wiring feeding the shed.

Further investigation revealed an existing electrical splice in the home’s crawl space. After evaluating the wiring, our electrician determined that the most reliable repair would be to rerun the circuit from the existing splice location to the outdoor shed.

Rather than simply restoring power temporarily, the goal was to provide a dependable electrical repair.

How We Repaired the Damaged Underground Electrical Wiring

Once the source of the electrical failure was identified, our electrician began the repair process.

The damaged underground wiring was replaced by running a new circuit connection from the crawl space splice location to the outdoor shed.

After installing the new wiring, our electrician restored power and tested the circuit to verify that everything was operating properly.

The result? Power was successfully restored to both the living room and outdoor shed.

This repair highlights why professional electrical troubleshooting is so important. Electrical issues aren’t always caused by the outlets, switches, or breakers homeowners can see. Sometimes the problem is hidden beneath the ground or within the home’s electrical system.

Signs Your Home May Have Damaged Underground Electrical Wiring

If your home has underground electrical lines supplying a detached garage, workshop, shed, or other outdoor structure, watch for these warning signs:

• Sudden loss of power to an outdoor building
• Circuit breakers that repeatedly trip
• Outlets or lights that stop working after nearby excavation
• Intermittent electrical power
• Multiple areas losing power on the same circuit

If you notice electrical problems following utility installation, landscaping, or trenching work, underground wire damage may be a possible cause.

Avoid digging around suspected damaged electrical lines or attempting repairs yourself. Underground electrical repairs should be handled by a qualified electrician.

Why Professional Electrical Troubleshooting Matters

Electrical problems can be difficult to diagnose without the proper training and equipment.

A qualified electrician can inspect the affected circuit, identify potential wiring damage, and recommend repairs that comply with applicable electrical codes.
