Thermal Camera Photo
This thermal camera photo was taken with a Sabertooth 2x60 running 40A continuously on both
motors. The left side is using 12ga stranded wire. The right side is using 8ga stranded wire. As
you can see, the 12ga wire is not only heating itself up due to being undersized, but it is also
causing heat to build up in the connections around it.
It is important to use adequately sized wire. Using undersized wire will
create added stress in the form of heat for the entire system and could
cause a premature failure!
