Receptacle supplies single-phase

 

 

 

 

 

 

 

 

power continuously. Frequency (Hz)

 

 

 

 

 

 

 

 

of generator power output changes

 

 

 

 

 

 

 

 

with engine speed. Total output avail-

tacle RC4 from overload. If CB3

 

 

 

 

 

 

 

 

opens, the receptacle does not work

 

 

 

 

 

 

 

 

and 115 volt ac output at RC4 stops.
