Tech Tip

There are limits on the overall amp capacity of the block based on the size of wire you are using.  This is because larger wires have the ability to dissipate more heat.  The overall limit when using 2/0 wires is 200 amps for the entire block.  If you use 4/0 wire the limit rises to 350 amps, and if you double up your 4/0 wire the max limit is 600 amps.
