Push the power switch on and check continuity. If current flows, it is normal.
Devices such as that shown in Fig. 92 are necessary for checking the circuit breaker if it properly operates. The rated current is shown on the side of the circuit breaker.
Adjust the load switch until the ammeter reads about twice the rated current marked on the circuit breaker. The circuit breaker is normal if it turns off

Check that a fuse is in the fuse holder and check its conti- nuity with a tester.
If there is no current, take the fuse out and check it for continuity. If the fuse carries current. the fuse holder is faulty. If the fuse carries no current, replace it with a fuse of the correct capacity, and check the fuse holder again for continuity.
