3.2 Fuse 

Specifications

 

All recommended  fuses  should  be connected 

in series in  circuit,  and  as  close as possible to 
power sources. Bolt  down fuses is preferred 
as they ensure  a low resistance  connection. 
Blade   type   fuses are  not  recommended  as 

they can  result  in

 

a  high  resistance  connection  which  can  cause  excess  heat  generation 
and may damage the fuse holder  and/or  the  wiring.  Self-resetting circuit 
breakers are not recommended as  they  may  prematurely  trip due to the 

heat generated by the large current 

owing  through  the wires.

 

Please  refer  to  the  table  below  for  the  recommended fuses.
