This is commonly referred to as the OSHA 10 foot rule. For example, a minimum approach distance of 2. It is important to note that the location for a service point may vary between utilities and occupancies; in addition, locally adopted utility service requirements may apply. It is always a good practice to verify what code is adopted in a jurisdiction and determine if there are any local amendments that must be applied to an installation. This holds true on both the utility side and the premises wiring side of the established service point.
The NESC is currently in its development cycle, and more information can be found at standards. The idea is to achieve appropriate coverage and correlation without conflict or duplication.
For example, a large-scale photovoltaic, wind or energy storage system installed and maintained under the exclusive control of a serving utility would not be covered by the NEC. In these cases, the applicable code should include the requirements for these installations or should provide users references between the codes.
