Section 20:10:36:15 - Isolation device

If required by the public utility, a small generator facility must be capable of being isolated from the public utility. When isolation is required, a small generator facility shall do so in one of the following ways:

(1) For a small generator facility interconnecting to a primary line, the isolation shall be by means of a lockable, visible-break isolation device readily accessible by the public utility;

(2) For a small generator facility interconnecting to a secondary line, the isolation shall be by means of a lockable isolation device whose status is clearly indicated and is readily accessible by the public utility;

(3) All other interconnection isolation devices shall be installed, owned, and maintained by the owner of the small generator facility and be capable of interrupting the full load of the small generator facility and shall be located between the small generator facility and the point of interconnection.

Alternatively, the applicant or interconnection customer may elect to provide the public utility access to an isolation device that is contained in a building or area that may be unoccupied and locked or not otherwise readily accessible to the public utility by providing a lockbox capable of accepting a lock provided by the public utility that will provide ready access to the isolation device. The applicant or interconnection customer must affix a placard in a location acceptable to the public utility that provides clear instructions to the utility's operating personnel on how to gain access to the isolation device.
