What are the procedure of start up of emergency AC Generator?

Hi I'm going to start up an emergency AC generator driven by Diesel engine that generate 220+ VOLTS but I don't know what are the procedure to start up of an AC generatorand also what are the procedure to STOP the generator. please help :)

Answer:

Is this generator going to be used in a location which is normally served by grid power. If so is it proposed to use the distribution system normally used when on the grid? If the answer to these questions is yes. The first step is to isolate the normal energy source. This has two purposes. a) to protect your equipment when power is restored and b) to protect people and equipment working on the external circuit. Once this is isolated wire the generator into the circuit (closing isolating switch if hard wired). Start the generator using normal procedures with minimal load in place. Slowly increase load until desired effect is achieved. When external power is returned. Slowly reduce load and isolate generator. Restore normal grid connection. Shut off generator.
