Electrical Cable Size Calculator Software Free !!HOT!! Download

This app uses the calculation requirements found in the 2017 National Electrical Code to determine the ampacity of insulated conductors and certain cable-type wiring methods. This calculator also complies with the 2020 NEC requirements. Certain installations (such as cable trays and medium-voltage conductors) are not included in this app. Insulated single conductors are assumed to be installed in conduit or direct buried. All calculations assume a voltage of no more than 2000 volts and that the appropriate NEC requirements are followed by the installer, engineer or other responsible party. For more information on ampacity calculations, please consult our technical resources.

Electrical cables are the lifelines of any electrical system, transmitting power from one point to another. Keeping in mind the very crucial job they conduct, choosing the right cable size in electrical installations is of utmost importance to ensure the safety, efficiency, and optimal performance. The longevity of your electrical devices and appliances also depends on the kind and quality of cable you use to connect them to the electrical supply. Hence it is important to choose the type of wiring and the size carefully.

Three-core-and-earth cables are commonly used in scenarios where additional connections are required. Similar to twin-core-and-earth cables, the cable sizes here also correspond with a current and wattage. However, these cables are only used for two-way switching of lights.

Remember to consult a qualified electrician or electrical engineer for complex installations or if you are unsure about cable sizing for critical applications. You may also speak with your chosen manufacturer to check the parity between cable sizes and applications.

You now know all about the importance of cable sizing and how to calculate optimum cable sizes using the electrical cable size calculator charts shared above. If you are still confused about cable sizing or wish to know electrical cable size chart amps for a specific application, the professionals at the Schneider Electric eShop are always available at your service.

The fault constant, K, is based on the insulation material, the initial conductor temperature, and the final conductor temperature. The calculator uses the maximum allowable operating temperature as the initial conductor temperature. For example, 75C is used for PVC insulated cables, 90C is used for XLPE insulated cables, and 110C is for XLPE 110C.

The minimum active cable size is provided which meets the current-carrying capacity and the maximum voltage drop requirements. Note that a cable size larger than this minimum is also acceptable and may be more economical in terms of electrical losses over its lifetime.

All marine electrical systems present a risk of fire and other hazards. Blue Sea Systems makes no representation or warranty that this calculator will be suitable to address your particular situation or requirements.

This calculator does not account for all possible variables and factors relevant to the selection of wire size and circuit protection. Such variables may include overloads (such as changing the size of light bulbs or adding additional loads to circuits), wiring errors (such as loose connections or poor crimps), heated terminations (such as motor terminals, heating appliances, or lighting fixtures), data input errors, unusual environmental heat sources, and inadequate or defective wire insulation, software defects, and/or malfunctions of a browser or server computer.

This calculator is not a substitute for the expertise of a marine electrical professional. Under no circumstances should this calculator be used as the sole basis for selecting wire size or circuit protection. Any wire size or circuit protection tentatively selected with this tool should be reviewed for adequacy, before installation, by a professional applying the applicable industry standards.

-desired voltage drop in % or in other words this is the cable resistive loss. Every cable has its own resistance which is directly proportional to the cable length and inversely proportional to the cable diameter. This resistance is temperature dependant as well. Our calculator takes into account all the above-mentioned factors to calculate cable resistance so as to be received a voltage drop equaled to the desired one.

Always choose cable type that satisfied both conditions: calculated wire diameter in inches (or cable wire size in mm2) and rated maximum ampers for power transmission if cables are wired in a bundle or maximum amps for chassis wiring if each wire is routed separately and exposed directly to air as per table given below calculator area or manufacturers data.

Many of our customers have been looking for an easy AWG To mm conversion tool so we've made one. You can just select your AWG size from the pulldown box and we'll tell you the equivalent cable. We've even included an AWG to mm Conversion Table further down the page.

When buying cut to length electrical wire or electrical cable, many UK and international buyers face difficulty when confronted with AWG sizing. Vice Versa, American buyers may be stumped when they are recommended a certain gauge of cable or wire, and don't know how to get it when confronted with mm.

For AWG 23 and upwards - When using a cable to power mains voltages: (110v, 230v etc) the smallest conductor we recommend is 0.5mm. For audio, video, telephone, security cabling you may want to use smaller cables sizes where the voltage and current are smaller.

Wire Gauges run low to high - this means that the smaller a gauge number, the larger it is in mm. Conversely, a large number in AWG equates to a very small number of mm.

AWG sizes do not fit perfectly into mm or inches, so you may need to round up or down when safe to do so.

Cable sizes (including AWG) refer to the size of the conductor, not the total thickness of the cable including sheathing etc.

Do not confuse AWG (American Wire Gauge) with SWG (Standard Wire Gauge, the now largely redundant British Imperial standard which was superseded by mm.) as they are not equal. Always double-check to make sure you are buying the correct thickness of wire or cable. e24fc04721
