0 gauge cable is a general term that refers to a wire size using the standard American Wire Gauge system. Typically, when people are searching for 0 gauge cable, they are looking for a large size cable that is capable of handling a high amount of amps, particularly for audio amplifiers, power inverters, arc welders, or batteries. Although a typical copper 0 gauge cable has a max current of approximately 150 amps and is reasonably safe for many large applications, there are other factors that should be considered when choosing the gauge size of your cable. Insulation type, ampacity rating, wire length, and electrical rating of the cable should meet your application requirements.
The insulation type that is important depends on the environment where you are planning to install your 0 gauge cable. PVC, XLP, Neoprene, EPDM, and other insulation types all have different specifications and are intended for different applications. EPDM and Neoprene insulated 0 gauge cables are highly durable, resistant to high temperatures, can be used for arc welding, and are suitable for harsh environments. PVC and XLP are good insulations to use in automotive settings.
The ampacity rating is important when choosing the gauge size of your cables. You will need to look for gauge sizes that can handle the electrical currents (amps) that your applications require. The ampacity rating is the safe current-carrying capacity of the wire before damage occurs to the insulation.
Since all wire conductors cause resistance to electrons traveling through the wire, the larger the distance the electrons have to travel, the greater the resistance. If you have a specific ampacity you must meet, the length of the 0 gauge cable should be considered.
