Voltage Drop by Run Length Chart for 12V Systems
Voltage drop on a 12V system is Vdrop = 2 x L x I x R, and the target is 3 percent, which is 0.36V. That means 10 AWG stays inside the target for 18 ft at 10A but only 3.6 ft at 50A, and a 185A inverter feed needs 2/0 to reach 10 ft. Run length, not ampacity, is what forces most 12V cable up a gauge.
Voltage drop is the second of the two tests every conductor has to pass, and on a 12V system it is almost always the one that decides the gauge. Ampacity asks whether the conductor is safe. Voltage drop asks whether enough voltage survives the journey to be useful at the other end. On 120V there is so much voltage available that a couple of volts lost in the cable is invisible. On 12V the entire budget for a critical circuit is 0.36V, out and back, and it disappears startlingly fast.
What is the voltage drop formula and why the factor of two?
The formula is Vdrop = 2 x L x I x R, where L is the one-way run length in feet, I is the current in amps, and R is the conductor resistance in ohms per foot. Everything else on this page is that one line applied several hundred times.
The factor of two is the part people leave out, and it is not a safety margin or a fudge. Current is a loop. It travels out along the positive conductor and returns along the negative one, so the copper it has to pass through is twice the physical distance between the battery and the appliance. A fuse block 10 ft from the battery is a 20 ft circuit. Omit the 2 and every answer you get is exactly half the real figure, which in practice means a conductor one or two gauges too small, an appliance that browns out under load, and a puzzled builder measuring 11.4V at a fridge that is supposed to be seeing 12.6V.
The target is 3 percent on anything critical. Three percent of 12V is 0.36V, and that is the number to hold in your head. It applies to the main DC trunk, to every charging run, to solar feeds, and to anything with a motor in it, because a motor running on low voltage draws more current to make the same mechanical power and therefore gets hot. Ten percent is acceptable on non-critical lighting only, where a marginally dimmer LED is the entire consequence.
Here is the resistance table everything below is built from. Ohms per foot is a property of the copper, not of the installation, so unlike ampacity it does not change with ambient temperature or bundling in any way you need to worry about at these currents.
| AWG | Ohms per foot | Ampacity outside engine space | Volts lost per 10 ft at 10A |
|---|---|---|---|
| 18 | 0.00639 | 20A | 1.278V |
| 16 | 0.00402 | 25A | 0.804V |
| 14 | 0.00253 | 35A | 0.506V |
| 12 | 0.00159 | 45A | 0.318V |
| 10 | 0.000999 | 60A | 0.200V |
| 8 | 0.000628 | 80A | 0.126V |
| 6 | 0.000395 | 120A | 0.079V |
| 4 | 0.000249 | 160A | 0.050V |
| 2 | 0.000156 | 210A | 0.031V |
| 1 | 0.000124 | 245A | 0.025V |
| 1/0 | 0.0000983 | 285A | 0.020V |
| 2/0 | 0.0000779 | 330A | 0.016V |
| 3/0 | 0.0000618 | 385A | 0.012V |
| 4/0 | 0.000049 | 445A | 0.010V |
Two worked examples, with the arithmetic shown
Example one: a compressor fridge. A 45 quart 12V compressor fridge draws about 6A while the compressor is running. Once the cable is routed around furniture rather than measured in a straight line, it sits about 15 ft from the fuse block. Start with 16 AWG, which is rated 25A and looks like far more than enough. The arithmetic is 2 x 15 x 6 x 0.00402, which is 0.72V. Divide by 12 and multiply by 100 and that is 6.0 percent, twice the target. Step to 14 AWG: 2 x 15 x 6 x 0.00253 = 0.46V, or 3.8 percent, still outside. Step to 12 AWG: 2 x 15 x 6 x 0.00159 = 0.29V, or 2.4 percent, and now it passes. Twelve AWG is the answer, and every one of those three conductors passed the ampacity test with an enormous margin. Voltage drop chose the gauge, not ampacity.
Example two: a 2000W inverter. DC current is AC watts divided by 12 times efficiency, so a Renogy Pro 2000W Pure Sine Wave Inverter 12V to 120V at full output and 90 percent efficiency pulls 2000 divided by 10.8, which is roughly 185A. Assume the inverter is 10 ft from the battery. In 2 AWG, which is rated 210A and passes ampacity: 2 x 10 x 185 x 0.000156 = 0.58V, which is 4.8 percent. At full load the inverter would see under 11.5V at its terminals and could shut down on low voltage while the battery is still half full. In 1/0: 2 x 10 x 185 x 0.0000983 = 0.36V, exactly on the line with no margin. In 2/0: 2 x 10 x 185 x 0.0000779 = 0.29V, comfortably inside. Two-aught it is, two full gauge steps above what ampacity alone would have permitted.
A third, because it is the one people get wrong most often. A solar controller delivering 30A to the battery over a 20 ft run in 10 AWG: 2 x 20 x 30 x 0.000999 = 1.20V, which is 10 percent and completely unacceptable on a charging circuit. In 8 AWG: 2 x 20 x 30 x 0.000628 = 0.75V, still 6.3 percent. In 6 AWG: 2 x 20 x 30 x 0.000395 = 0.47V, 3.9 percent, and only 4 AWG at 0.30V finally passes. Charging circuits are the least forgiving of all, because a controller trying to hold 14.4V at its own terminals is only delivering 13.9V at the battery, and the battery never reaches absorption. Mount the controller close to the battery and run the long cable on the panel side where the voltage is higher and the current is lower. A 150V input controller lets you wire panels in series and cut the roof-run current dramatically, which is the cheapest fix there is.
What is the voltage drop at every gauge and run length?
These are the grids. Each table is one current. Rows are gauges that are rated to carry that current outside engine spaces, columns are one-way run lengths in feet, and each cell is the percentage of 12V lost in the cable. Bold cells are inside the 0.36V, 3 percent target. Everything not bold fails for a critical circuit.

Read down a column and the pattern is obvious: at any fixed length, each step up the even-numbered gauges, 12 to 10 to 8 and so on, buys roughly a 37 percent reduction in loss, so you need two of those steps to cut it by more than half. Read across a row and the loss climbs in a straight line with distance, which is why the single most effective thing you can do about voltage drop costs nothing at all: move the load closer to the battery, or move the battery closer to the load.
Notice how few bold cells survive at 100A and 185A. At 185A there is essentially no such thing as a long run. Even 4/0, the fattest cable most builders will ever handle, is out of budget past about 20 ft. This is not a defect in the table, it is the reality of moving kilowatts at 12V, and it is the reason a well planned build puts the battery, the inverter, the shunt and the main busbars inside the same cubic foot or two. Everything low-current can then run anywhere it likes.
What is the longest run I can use for each gauge?
Rearranging the formula for L gives the maximum one-way run that stays inside 0.36V: L equals 0.36 divided by the product of 2, the current and the ohms per foot. That single number per gauge per current is often more useful than a grid, because it tells you directly whether the cable you already own will reach.

Cells marked n/a are gauges not rated to carry that current at all, so the question of run length does not arise. Everything else is a real distance in feet, and the numbers are unforgiving. Ten AWG reaches 18 ft at 10A and 3.6 ft at 50A. Two AWG reaches 23 ft at 50A and 6.2 ft at 185A. The relationship is a simple inverse: double the current and the reach halves.
Use this table backwards when you are planning a layout rather than sizing a cable you already committed to. Measure the route the cable will actually take, including the vertical drops and the detours around a wheel arch, then look up the current and find the first gauge whose reach exceeds it. Then check that gauge against the ampacity chart and take whichever of the two answers is larger. That is the whole method, and the wire gauge calculator does it automatically if you would rather not.
Why does 24V solve so much of this?
Power is volts times amps. If the system voltage doubles, the same appliance draws half the current, and every consequence of current gets better at once. Voltage lost in the cable is proportional to current, so it halves. Percentage lost is that halved voltage measured against a doubled system voltage, so it falls to a quarter. Power wasted as heat in the cable is current squared times resistance, so it also falls to a quarter. Nothing about the copper changed. Only the current did.
The table below is the same 2000W inverter load over the same 10 ft one-way run, once at 12V where it draws 185A and once at 24V where it draws 93A, both at 90 percent efficiency.
| AWG | 12V drop | 12V percent | 12V watts lost | 24V drop | 24V percent | 24V watts lost |
|---|---|---|---|---|---|---|
| 4 | 0.92V | 7.7% | 170.8W | 0.46V | 1.9% | 42.7W |
| 2 | 0.58V | 4.8% | 107.0W | 0.29V | 1.2% | 26.7W |
| 1/0 | 0.36V | 3.0% | 67.4W | 0.18V | 0.8% | 16.9W |
| 2/0 | 0.29V | 2.4% | 53.4W | 0.14V | 0.6% | 13.4W |
| 4/0 | 0.18V | 1.5% | 33.6W | 0.09V | 0.4% | 8.4W |
The practical translation is that a 24V system running a 2000W inverter can use 4 AWG where a 12V system needs 2/0, and 4 AWG is roughly a third of the price per foot, a third of the weight, and far easier to bend around a corner in a cabinet. The watts lost column is worth a second look too: at 12V in 2 AWG the cable itself is dissipating over 100W as heat inside your vehicle, which is a small electric heater you did not ask for and did not budget any amp-hours to run.
None of that makes 24V automatically correct. Twelve volts remains the right answer for most vehicle builds because fridges, fans, pumps, lights and sockets are overwhelmingly 12V products, and a 24V house bank means either buying scarcer 24V appliances or adding a step-down converter that has its own losses and its own failure mode. The 12V versus 24V house system comparison works through where the crossover genuinely sits, and it is higher up the system size range than the cable arithmetic alone suggests.
What else eats voltage besides the cable?
Everything in series with the load, and the cable is often not the largest contributor. A poor crimp, a corroded ring terminal, an undersized busbar stud, a cheap battery switch, a blade fuse holder run near its rating and a chassis ground onto rusty painted steel all add resistance in exactly the same way copper does, except concentrated in one spot where the heat has nowhere to spread. A connection that adds 5 milliohms to a 185A circuit is dropping 0.93V on its own, which is more than the entire cable budget, and dissipating 170W in a lug.
This is why terminations get the attention they do. You cannot hand-crimp a heavy lug properly, and a Brileine 10 Ton Hydraulic Lug Crimping Tool (12 to 2/0 AWG, 9 dies) is the cheapest genuine safety item in a build. Crimp tinned TKDMR Copper Wire Lug and Ring Terminal Kit (2 to 12 AWG, 160 pieces) and seal each one with adhesive-lined Adhesive Lined 3:1 Heat Shrink Tubing Kit (400 pieces) so water never reaches the strands. Give every cable its own torqueable stud on a pair of Joinfworld 12V 250A Busbar Power Distribution Block (4 x 3/8 in studs) rather than stacking ring terminals on a battery post, because the bottom terminal in a stack loses clamping force first and a loose 200A joint is a genuine fire risk.
Two more sources are worth naming. Temperature: copper resistance rises roughly 0.4 percent per degree C, so a cable running at 70C has about 15 to 20 percent more resistance than the room temperature figure in the table. That is a real effect but a second-order one, and designing to 3 percent already absorbs it. And the negative side: it carries exactly the same current as the positive side and must be exactly the same size. Relying on the chassis as a return path through a rusty seam is where a surprising number of mysterious voltage drops come from. Bond the negative busbar to the chassis at a single prepared point, downstream of any shunt so the Victron SmartShunt 500A Battery Monitor still counts every amp.
Then verify it. Read the voltage at the battery terminals and at the appliance at the same instant under real load, and the difference is your actual drop. A AstroAI Digital Clamp Meter, AC/DC Current and Voltage (4000 count) lets you confirm the current at the same time so you know which row of the table you are actually on. A measured drop far above the calculated one is almost never the copper. It is a joint. Everything here is researched guidance drawn from published standards and manufacturer documentation rather than an electrical certification, it does not replace ABYC E-11 or your component manuals, and a lithium installation should be inspected by a qualified installer before it carries load.

Frequently asked questions
How do I calculate voltage drop on a 12V circuit?
Use Vdrop equals 2 times L times I times R. L is the one-way run in feet, I is the current in amps, and R is the conductor resistance in ohms per foot. A 6A fridge on 15 ft of 12 AWG works out as 2 times 15 times 6 times 0.00159, which is 0.29V, or 2.4 percent of 12V. Divide the result by 12 and multiply by 100 to get the percentage.
Why is the voltage drop formula multiplied by two?
Because the current has to get back. It travels out along the positive conductor and returns along the negative one, so the copper in the circuit is twice the distance between the two ends. A battery 10 ft from a fuse block is a 20 ft circuit. Dropping the factor of two halves your calculated loss and typically produces cable one or two gauges too small, which is the most common sizing mistake in DIY builds.
What percentage voltage drop is acceptable on a van build?
Three percent on anything critical, which on a 12V nominal system is 0.36V. That covers panel feeds, the main DC trunk, every charging run and anything with a motor in it, because a motor on low voltage draws more current and runs hotter. Ten percent is acceptable on non-critical lighting alone, where the only consequence is a marginally dimmer LED. When you cannot decide which category a circuit falls in, design to three percent.
Does a shorter run really let me use much smaller cable?
Yes, and it is the cheapest change you can make. Voltage drop is directly proportional to length, so halving the distance halves the loss. A 185A inverter feed over 10 ft needs 2/0 to stay inside 0.36V, while the same load over 5 ft passes in 2 AWG. Two AWG costs roughly half what 2/0 costs per foot, so moving the inverter next to the battery saves money twice.
How much does 24V improve voltage drop?
The same appliance at 24V draws half the current, so the volts lost in the cable halve, and because the system voltage has doubled the percentage lost falls to a quarter. Power wasted as heat, which is current squared times resistance, also falls to a quarter. A 2000W inverter feed over 10 ft loses 4.8 percent in 2 AWG at 12V and 1.2 percent in the same cable at 24V.
Should I measure voltage drop instead of calculating it?
Do both. Calculate it before you buy cable, because that is the only way to choose a gauge, then confirm it afterwards with a meter under real load: read the voltage at the battery terminals and at the appliance at the same moment, and the difference is your actual drop. A measured figure much higher than the calculated one almost always means a poor crimp or a corroded terminal rather than undersized copper.
Electrical safety: 12V is low voltage but not low energy. A lithium house battery can push several hundred amps into a short circuit, and undersized or unfused cable is one of the most common causes of vehicle fires in DIY builds. Every circuit must be fused at the source of power, within a few inches of the battery terminal, at or below the ampacity of the smallest conductor it protects. Size cable for voltage drop as well as ampacity, torque terminals to specification, and have a lithium installation inspected by a qualified installer before it carries load. The figures on this page are researched guidance, not a substitute for ABYC E-11 or your component manufacturer's installation manual.
How we choose: we compare published manufacturer specifications, standards documents including ABYC E-11, and verified owner reviews. We do not test gear in person. Vehicle payload, roof load and charging limits vary by model and year, so confirm yours against the door jamb sticker and the owner's manual rather than any number published here.
