TUOFENG 12 Gauge Silicone Wire -6 Meter [3 m Black and 3 m Red] 3.3mm² Soft and Flexible Electrical Wire for DIY Projects and Electrical Applications

Product Information

Firstly, it is lighter, meaning that there can be significant weight savings in large wiring harnesses and this is one the main drivers behind it having now been adopted by almost all vehicle manufacturers for their electrical systems. In the US, the most commonly used wire gauge system is AWG, or American Wire Gauge. The higher the gauge number, the smaller the wire.

The table below provides a cross-reference between these two standards, showing the closest metric equivalents to each Gauge for cable sizes commonly used in low voltage automotive and marine applications. AWG It has sufficient current rating for the expected load in the circuit, including a margin of safety.

You might find it useful to read our Electrical Circuit Basics article for using the equation I = P/V where the following example is given: Thirdly, the harder grade of PVC is more reistant to abrasion and cutting than standard PVC, offering more protection and greater reliability. conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F). Select which electrical system you will be using. Either DC/AC Single-phase or AC Three-phase. That means the calculator can be a simple DC wire size calculator, all the way up to an AC three-phase tool.

Select the wire conductor material, either copper or aluminum. You can also use Advanced mode to set a custom material resistivity at a fixed temperature.If this AWG metric calculator doesn't provide you with the information you need, please get in touch with the technical experts of The Cable Lab who will be pleased to answer your questions or calculate the appropriate AWG/metric size for your installation. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including Secondly, it has a greater working temperature range with a maximum of around 105ºC compared with around 70ºC for standard PVC. This makes it more suited to use in areas close to the engine. In most situations the detrimental effects can be minimised by using shrink sleeving, sealed connectors, adhesive lined terminals, protective gels etc. to keep moisture out, but in some applications where the environment is particularly aggressive, for example marine use, it might be preferable to use cable with tinned conductors. This is simply where the standard plain copper conductor has has a layer of tin applied before being sheathed in the insulation.Tin doesn't react in the presence of moisture, yet retains good conductivity, and so improves long-term performance of the cable. The downsides are that it is slightly more expensive and there is a more limited range of sizes and colours available compared with plain copper. Earth braid straps that have no insulating layer are typically tinned for protection as a matter of course. So we want to select a cable to make sure that the voltage drop is not so large that it will cause problems, but what is acceptable and how do we calculate the right cable size to use? Well the generally acceptable voltage drop for DC circuits is around 3-4% and we can use V = IR (see Electrical Circuit Basics) to calculate the voltage drop for a cable if we know the current draw of the load and the cable's resistance per metre.
