Manage your Circuit Resistance The load-wiring-calculator will give you a very simple and quick solution to the problem of calculating the size of wires and DC maximum load for LED power transmission. This is a calculator for the estimation of the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current If this circuit is constructed with 14 gauge wire, the maximum allowed amperage rating of 15 amps would be exceeded, causing the fuse to blow. To find wattage, you multiply amperage by voltage. Example: To find the maximum wattage that a 14 gauge wire circuit can safely accommodate: 15 amps x 120 volts = 1800 watts - The calculator allows entry of a voltage drop, but caution should be used when doing so to make sure you are calculating the wire sizes in accordance with NEC article 210-19 (FPN No. 4.) The NEC allows a maximum of a 3% voltage drop on the main branch of a circuit at the farthest outlet of power and 5% total to both feeders and branch.

DC Fuse Size Calculator Use this calculator to select the appropriate fuse size for your load and wiring. If you are simply replacing a fuse it is recommended to use the same size fuse unless you are experiecning nusiance fuse blows or your wire melted without the fuse blowing. Select AWG Wire Size Step 1: Determine your amplifier's fuse rating (in amperes), check the owner's manual that came with your product. If you have more than one amplifier, simply add the fuse ratings together. Step 2: Determine how long the power wire length will be from your vehicle's battery to your amplifier This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current. In addition, experiment with the resistor and Ohm's Law calculator, or explore hundreds of other calculators addressing math, finance, fitness, health, and more

Tim, The fuse at the battery is there to protect the wire and your car in the event of a short circuit. 4-gauge wire should be protected by a fuse anywhere from 75A to 125A in size. Your figuring is correct: you can use 100A fuse at the battery and a 60A for the sub amp and 40A for the 4-channel Or, one can determine the wire diameter for a given material and fusing current so that a larger size wire can be selected to avoid fusing. where I f is the fusing current in amps, C is Preece's Coefficient for the particular metal in use, and d is the fuse element diameter in inches. William Henry Preece determined this relationship in 1884 by comparing the balance between the heat. Wire directly terminated at a fuse is subject to this additional heat and may fail at the termination even if the rest of the wire is within its temperature limits. Larger wire may be recommended when it is terminated on a fuse and the duration of usage is long

Product list and cost of components Recommended Wire Gauge Calculator Our recommended wire gauge calculator helps determine the correct wire gauge for your application based upon the input parameters of length, current, voltage and more. The recommend gauge is the result of applying ABYC Standards factors, allowable voltage drop and any additional derating factors To use the calculator, enter the Maximum Current in Amps of the circuit, and the Length of the Wire, and operating Voltage. Typically most automotive systems run at 13.8V, but you can select 6, 12, 13.8 (Default) or 24 volts. If the wire gauge is OK to use it will have a 'Check Mark' on the same line Enter both Load (between .125 and 6 Amps) and Length (25 - 350 Ft.) values to calculate Wire Gauge Size. For both 12V and 24V Calculators, entering values that will exceed minimum Wire Gauge Size upon calculation, the result will be Value of minimum wire gauge Not Available. You will need to either reduce the Load and/or the Length values to get a result Choosing the correct gauge automotive wire depends on the acceptable voltage drop, length of the feeder/branch circuit conductor, load amperage, and the ambient temperature of the compartment where the primary wire will pass through. Outside engine compartments, the ambient temperature should generally be 20°C. Choose a higher ambient temperature when conductors are expected to pass through.

The Wire Size Calculator below will calculate the proper wire size for a circuit based on circuit amps, preferred (or available) wire insulation, conductor type and installation specifications. For more advanced considerations, use the Wire Size Calculator or the Advanced Wire Size Calculator. Quick Wire Size Calculator Use a calculator to divide the number of watts by the voltage. In the case of a 110-volt circuit, using 1200 watts, the calculation would be: 1200/110=10.9 amps. For a household circuit, a 15-amp fuse should be used in this circuit. A 10-amp fuse would blow-out consistently before the necessary power was delivered

A 5A fuse can only handle 4A continuously, NOT 4.8. A 6A or 7.5A fuse will blow before wiring is compromised IF the wire is properly sized. A 10A fuse is pushing it, and with a 20A fuse, you may as well use a copper (pre-1982) penny. No matter how many amps a downstream device wants, the unit is maxed out @ 4.8 Wire that supports more than 2 times the maximum current flow is often used, to reduce voltage loss due to the wire.

Ohm's Law Calculator 3-Phase Delta / Wye Calculator. User manuals, specification sheets, CAD drawings and more. Leverage Watlow's growing toolkit of calculators, equations, reference data and more to help design your thermal system Over 10 feet and voltage drop becomes an issue. So while say a 20 amp fuse with 15 amp load is good at 10 feet using 12 AWG. At 20 feet will incur some voltage drop, thus power loss. You still use the same 20 amp fuse but use a larger 10 AWG wire. You can use as large of a wire you want on a fuse to counter Voltage Drop It is important to understand the relationship between wire gauge and amperage. To do this we will look at the original fuse. The original fuse was a piece of wire sized to melt when a specific amount of amps (current) was going through it, as shown in Figure 3. Figure 3 - The fuse element, on the left of the picture, is what is inside the. 3 phase motor cable size calculator is developed for designing the three-phase electrical motors starter's material such as internal cable wiring, outgoing cable calculation, required cable gland size, Cable connector size, overload relay size, required fuse size, circuit breaker, MCCB size, MPCB size, cable lug size, and the terminal block size for all the electrical motors

The cable sizing calculator considers current rating, voltage drop and short circuit current according to the IEC 60364 and HD 60364 standards. See also calculator for AS/NZS 3008, and NEC There is a formula for working out the fuse rating, voltage or wattage for each appliance P (Power in Watts) = V (voltage) x I (current in Amps) The fuse rating can be calculated by dividing the power used by the appliance by the voltage going into the appliance. I (Amps) = P (Watts) ÷ V (Voltage For example, fuses, MCBs, MCCBs. The let-through energy is available on curves from the device manufacturer. MCB (A): A current limiting MCB.

How To Use The Cable Size Calculator 1 - Enter percentage cable loss acceptable [normally approx 2 or 3%]. 2 - Enter nominal system voltage [or pv array voltage for solar cables]. 3 - Enter max amps to be carried by the cable [amps = watts / voltage]. 4 - Enter length of cable run required [power source to load] The fuse used at the battery or at a distribution block is to protect the cable downstream, not the amp. Always fuse for the cable size. Always use no larger fuse than the smallest wire in the power chain before the next fuse and always use a new appropriately-sized fuse if the cable gauge is lowered The simple version? You can only run about 240W from your cigarette lighter (20A fuse). Maybe only 180W (15A fuse). To run more, you'll need to run a wire to the battery. To get the wire size, take the power draw of your largest appliance and divide it by 12 to get the current draw. In our example 1250W/12V= 104A A 10 amp fuse will protect the 16 gauge wire from being overloaded. So, if you plug an accessory into the rear plug that draws more than 10 amps, the fuse will protect the circuit from overload. If the wire size is 14 gauge, you can then use a 15 amp fuse in 15' or wire
