B. An interconnection customer shall separate from the utility system in the event of any one or more of the following conditions:

(1) a fault on the generating facility's system; or

(2) a generating facility contribution to a utility system emergency; or

(3) abnormal frequency or voltage conditions on the utility's system; or

(4) any occurrence or condition that will endanger utility employees or customers; or

(5) a generating facility condition that would otherwise interfere with a utility's ability to provide safe and reliable electric service to other customers; or

(6) the sudden loss of the system power.

C. The utility may temporarily disconnect the generating facility upon the following conditions:

(1) for scheduled outages per notice requirements in the utility's tariff or commission rules;

(2) for unscheduled outages or emergency conditions pursuant to Subsection B of 17.9.568.29 NMAC;

(3) if the generating facility does not operate in the manner consistent with these terms and conditions;

(4) the utility shall inform the customer in advance of any scheduled disconnection, or as is reasonable after an unscheduled disconnection.

D. A visible-open, load break disconnect switch between the generating facility and the utility system that is visibly marked "generating facility generation disconnect" and is accessible to and lockable by the utility is required for all generating facilities except for those generating facilities with a maximum capacity rating of 10 kW or less that use a certified inverter including a self-contained renewable energy certificate (REC) meter and either:

(1) a utility accessible AC load break disconnect; or

(2) a utility accessible DC load break disconnect where there is no other source of generated or stored energy connected to the system.

E. Interconnection customers shall post a permanent and weatherproof one-line electrical diagram of the generating facility located at the point of service connection to the utility. Generating facilities where the disconnect switch is not located in close proximity to the utility meter must post a permanent and weatherproof map showing the location of all major equipment including the utility meter point, the generating facility generation disconnect, and the generating facility generation breaker. Non-residential generating facilities larger than 10 kW shall include with or attached to the map the names and current telephone numbers of at least two persons authorized to provide access to the generating facility and who have authority to make decisions regarding the generating facility interconnection and operation.

F. If the generating facility interconnection equipment package is not certified or if a certified equipment package has been modified, the generating facility interconnection equipment package shall be reviewed and approved by a professional electrical engineer, registered in the state of New Mexico.
