Production meter required

Provide copies of One-Line Diagrams showing the generation facility equipment; this is required for all projects. Projects over 150 KW in size require the One-Line Diagrams to be signed and stamped by a licensed Electrical Engineer (PE).

Install Reqs: The customer shall provide a lockable disconnect switch which meets NEC requirements and is accessible by first responders as per NEC requirements. This switch shall also be accessible by the Utility’s employees, and may be used to prevent parallel operation under certain circumstances. Contact your local utility as they may have additional requirements for the disconnect. The disconnect switch shall be clearly marked ‘Generator Disconnect Switch’ with permanent letters, a minimum of 3/8 inch high. The preferred location of the generator disconnect switch is that it be located outdoors within 10 feet of the Utility’s electric service meter. With your local utility’s approval, the generator disconnect switch may be located in some other accessible location, however in this circumstance, there shall be a placard placed at the service location giving directions to the location of the disconnect per NEC.
