Electronic meters are not designed to be de-energized for any length of time.
• TRANSFORMER UPGRADE If a Customer with a proposed Generating Facility is served from a AIC distribution transformer that also serves other customers, and if the Maximum Capacity of the proposed Generating Facility in aggregate with any existing customer Generating Facilities on the shared transformer exceeds 75% of the transformer nameplate rating, the Customer may be required to upgrade the transformer (at the Customer’s sole cost) or to be served from a dedicated transformer.

Install Reqs

The switch handle shall be capable of being locked in the “open” position by a standard AIC padlock with a 3/8” shank. The switch front cover shall be kept locked at all times by a AIC-furnished padlock. The front cover hasp shall be capable of accepting a 3/8” shank padlock, and shall not be field modified in any way.

Customer shall install, at Customer's expense, a DG meter socket, and any necessary metering cabinets to house AIC metering equipment required for measuring and recording the AC energy production of the Generating Facilities. If such metering is not required, AIC will inform the Customer in writing.

Customer-furnished DG metering sockets and cabinets shall be selected and installed in accordance with the AIC Electric Service Requirements.

Placards

AIC requires specific warning labels to be affixed to the Customer SES, DG Disconnect Switch, and DG meter. Required warning labels are available for purchase from Border States Electric, a AIC-preferred supplier. Customer may also furnish their own warning labels if they identically match those approved by AIC. All AIC-required warning labels shall be permanently affixed to the fronts of their respective equipment enclosures using rivets or screws. Use of glue or other adhesives is not permitted. Black on orange background. Please refer to Interconnection Manual.
