Underground Electric Installation: Solutions To Common Problems

Underground electric installation can be a cost-effective way to protect your access to power during storms or other natural weather events. When it comes to underground electric installation, however, you need to ensure that the job is done right to avoid costly repairs and/or power interruptions. 

Here are steps to take when considering underground electric installation:

Digging, Waterproofing, and Corrosion Resistance

Underground electric installation represents a substantial initial investment. If installed properly, particularly in areas with turbulent weather events like hurricanes, tornados, or blizzards, underground electric installation can offer substantial protection and value.

  • Plan and Mark: one of the most common issues with underground electric lines is caused by improper digging or trenching, or by nearby construction or landscaping activities. To prevent this, make sure to mark the location of underground cables before beginning any digging, and follow proper excavation techniques to minimize the risk of damage. If a cable is damaged, it will need to be repaired or replaced. When planning the location of your underground electric lines, it's important to contact your local utility provider and obtain appropriate permits with your local municipal building authority.
  • Waterproofing: water can seep into underground cables and cause them to short circuit, leading to outages and other problems. To prevent this, make sure to properly seal and waterproof all underground connections and splices. Because your power lines will be buried, you won't be able to fix water issues without completely digging up the lines. Thus, you should consider adding extra protective measures like casing your lines in PVC piping.
  • Corrosion Protection: underground cables and equipment can be vulnerable to corrosion, especially in areas with high humidity or salt water. To prevent corrosion, use corrosion-resistant materials and coatings, and regularly inspect and maintain the system to identify and address any signs of corrosion.

Power Issues and Connection Problems

Underground electric installation should help you avoid future issues with voltage and connection problems. However, these problems can occur if the installation process isn't completed properly.

  • Voltage Issues: this can occur when the electrical load on the underground system exceeds the capacity of the cables, causing the voltage to drop. To prevent voltage drop, make sure to properly size the cables and equipment for the electrical load, and distribute the load evenly across the system.
  • Connection Issues: loose or poorly made connections can cause a variety of problems, including outages, voltage drop, and overheating. To prevent this, make sure to properly terminate and splice all connections, and regularly inspect and tighten any connections that may have become loose over time.
