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.

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

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.

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. Fuse Type. The most critical aspect of fuses, is the fuse holder.

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.

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
