For interconnection equipment to be considered lab-tested equipment under these rules, the equipment must be used in a manner consistent with the certification.

(19)

“Line section” means that portion of a public utility’s transmission or distribution system that is connected to an interconnection customer and bounded by automatic sectionalizing devices or the end of a distribution line.

(20)

“Minor equipment modification” means a change to a small generator facility or its associated interconnection equipment that:

(a)

Does not affect the application of the approval requirements in Tiers 1, 2, or 3;

(b)

Does not, in the interconnecting public utility’s reasonable opinion, have a material impact on the safety or reliability of the public utility’s transmission or distribution system or an affected system; and

(c)

Does not affect the nameplate capacity of a small generator facility.

(21)

“Nameplate capacity” means the full-load electrical quantities assigned by a facility’s designer to a generator and its prime mover or other piece of electrical equipment, such as transformers and circuit breakers, under standardized conditions, as expressed in amperes, kilovoltamperes, kilowatts, volts, megawatts, or other appropriate units. Nameplate capacity is usually indicated on a nameplate attached to the individual device.

(22)

“Nationally recognized testing laboratory” or “NRTL” means a qualified private organization that performs independent safety testing and product certification. Each NRTL must meet the requirements set forth by the United States Occupational Safety and Health Administration.
