		  Hi - Â This is my first question for the forum. Â 



 I am building RV8 w single aft battery/ dual alternator.Â  Ground power contactor and battery master battery contactors are aft. Â  Obtained both contactors from B&C with 1N5400 diodes.Â  Total of 3 diodes Â (2 Â on the Ground Pwr Contactor Â and Â 1 on the Battery Master Contactor.)



 Diagram from Aircraft Spruce with the Piper jacks written by AeroElectric Â showed using 1N5402 diodes on Â the Â Ground Pwr contactor.Â  Are there compelling reasons Â to Â swap out Â my 1N5400 diodes with 1N5402 or other?



 ThanksÂ for reading and for responding. 	


   The 1N54xx series devices are essentially

   identical for our purposes. The XX denotes

   reverse voltage rating that range from 50

   to 1000 volts. See:



  https://www.vishay.com/docs/88516/1n5400.pdf 



   For our purposes, any of those devices

   will be operated within limits on a

   14v aircraft.
