Can we pump over power lines or under them?
You MUST maintain 20 feet clearance from any power line carrying up to 350,000 volts, and maintain 50 feet of clearance for any power line carrying more than 350,000 volts. When working around wooden or concrete power line poles, maintain 20 feet of clearance. If the wires are mounted to a steel pole, maintain 50 feet of clearance. This distance accounts for high humidity, wind, lapses, poor vision and equipment malfunctions. If electricity enters your boom from contact OR arcing, you were too close and you were breaking the law.
