Load bank testing shall be performed for a period of four (4) hours at the full rated load of the generator, and witnessed by a County representative. Salt water brine tank load banks are not acceptable for this purpose and are disallowed and will not be utilized for this test.
The test instrumentation will serve as a check of the generator set meters. The load bank will be capable of definite and precise incremental loading and shall not be dependent on the generator control instrumentation to read voltage and amperage of each phase. The load test shall use dry type load banks specifically utilized for this purpose. As a minimum, a load bank test performed in accordance with NFPA 110 section 5-13.2 (copy of which is included at the end of this section) as modified by the County shall be conducted.

The test results shall be submitted to and approved by the County before the generator set is accepted. An authorized representative of Anne Arundel County will also witness the acceptance tests. Acceptance testing of the installed generator set shall be conducted by a factory trained representative of the generator set manufacturer. Tests shall be performed as installed on-site.
