# §25.1363. Electrical system tests.

- (a) **When laboratory tests of the electrical system are conducted—**
  - (1) The tests must be performed on a mock-up using the same generating equipment used in the airplane;
  - (2) The equipment must simulate the electrical characteristics of the distribution wiring and connected loads to the extent necessary for valid test results; and
  - (3) Laboratory generator drives must simulate the actual prime movers on the airplane with respect to their reaction to generator loading, including loading due to faults.
- (b) For each flight condition that cannot be simulated adequately in the laboratory or by ground tests on the airplane, flight tests must be made.
