Distance of power lines from distribution box to equipment

The minimum safe distance from a power line depends on the voltage, the type of activity, and what's nearby, but the most widely recognized baseline is 10 feet for any person or piece of equipment near lines carrying up to 50,000 volts. That figure comes from federal workplace safety regulations. Before beginning equipment operations, the employer must: Identify the work zone by either: Demarcating boundaries (such as with flags, or a device such as a range limit device or range control warning device) and prohibiting the operator from operating the equipment past those boundaries, or.
