WIRING AND VOLTAGE
TECH TIPS
VOLTAGE IS MUCH LIKE WATER PRESSURE.
When calculating proper wire sizing, voltage plays a very important role.
Voltage is much like water pressure. The higher the voltage, the faster the current flows.
A 24 volt system can move the same amount of current through
a wire one half the size required for a 12 volt system.
This is also shown in the charging cable size chart on the following page.
Notice that the 24 volt cable size requirements are much less than that of the 12 volt.

of flow. 1/2 inch diameter hose allows
1 gallon per minute of flow at 24 volts.
