Screw connection  
Within each device size, the terminals are identical. The current which the various devices of 
a particular size are able to switch is also the same. This means that the same tool, torque, 
and conductor cross-section is used when working on all SIRIUS Innovations products of the 
same size. The stripped lengths are identical too; this is important for pre-assembled cables. 
Size S00 and S0 devices feature screw-type terminals with captive screws and terminal 
washers. The screw-type terminals also allow for the connection of 2 conductors with 
different cross-sections.
