Install Reqs

Contact the cooperative directly to schedule a TDR, no fees specified from Rep

"A manual load-break disconnect switch or safety switch with a clear visible indication of switch position between the CES and the Distributed Resource. The switch must have pad lock provisions for locking in the open position. The switch must be visible to, and accessible to Cooperative personnel. The switch must be in close proximity, and visible from, the Member’s point of common coupling with the CES. The switch must be labeled “Generator

Disconnect Switch”. The switch may isolate the Distributed Resource system and its associated load from the CES or disconnect only the Distributed Resource from the CES."

Placards

"Member will install a permanent warning label in a conspicuous place in close proximity to the electric meter or on the meter base to notify them personnel that there is a generator installed on the load side of the meter. The warning label shall not be placed in a

location that would interfere with the ability of Cooperative personnel to read the electric meter. Member shall also place a warning label on the Isolation Device. Cooperative will provide the warning labels to Member. The warning labels must be in place before the Distributed Resource can be interconnected with Cooperative’s system."
