Wiring a 12-volt DC circuit requires a working knowledge of electronics and circuitry. It is important to note that when working on any electrical system, there is an inherent risk of shock and even electrocution. Knowing the standards for wiring a system can help to prevent shorts in the wiring, reducing the overall maintenance required. Usually, a 12-volt system in a home implies the installation of a renewable energy (RE) system such as solar panels. Wiring in series will increase system voltage, adding the individual power sources’ voltages together. Series circuits have opposing terminals wired together, negative to positive, using 8-gauge wire. Wiring in parallel keeps the voltage the same while increasing the amperage of the system by adding each of the individual power source’s amperages together. A parallel circuit is wired by connecting like terminals, positive to positive and negative to negative. A series-parallel circuit utilizes both wiring configurations and creates different amperages and voltages as needed. Writer Bio
