Hello,



I am installing my ANL mounting base on my firewall. I have a 60 AMP alternator and my loading chart shows a continuous load of approx. 30A with max load (landing config. lights plus flaps, fuel pump  etc.) of up to 47 or 48A.



Is a 40A ANL suffient or should I install a 50A or 60A ANL?



Best regards,



Andrew.

   ANL current limiters are exceedingly robust with

   respect to their ratings. See:



http://www.aeroelectric.com/Mfgr_Data/Fuses_and_Current_Limiters/Bussman/ANL_Specs.pdf



   Bussman only makes 35, 50 and 80A values in the

   lower ratings at the time the data sheet was published.

   Other manufacturers may have other selections in

   this range. If you can put your hands on even a 35A

   ANL, it will be fine for your application since it

   carries 80A continuously.

Andrew,



If you're pulling 30 amps all day long a 30 amp ANL won't even flinch and probably your best bet for that rating.
