For 24V, the shortest wire run listed in the table longer than 200ft is 225ft. The fuse should be placed inline on the positive battery cable (+ or red colored cable) and within 1 foot (12 inches or less) from the battery.įor Live help, Call us M-F 9a-5p (PST) at 1.800.231.5806. 1) The electric strike is rated for 300mA 24VDC, therefore, you would select 500mA from the table. *Take note: At the bottom of the chart is the recommended fuse for your inverter size. By matching load current (in AMPs) across the top of the chart with wire gauge (AWG) down the left side of the chart, one can determine voltage drop per 100. MCM numbers are read as “350 MCM” or “500 MCM”. kcmil and MCM cable sizes are interchangeable numbers for large diameter wire/cables. If the number ends with a “k” designation, it is short for “kcmil”. This is a standard electrical wire number read as “6 AWG”, "4 AWG", or “00 AWG” and is universally understood. Now that you’ve located your cable number, what does it mean? If it is just a number by itself (6, 4, 2, 0, 00, 000, 0000, etc.), then it represents an American Wire Gauge (AWG) size. So, 3x 4AWG cables can replace one 4/0 cable. A single 4AWG cable can carry a maximum of 105A. For instance, a single 4/0 (0000) cable can carry a maximum of 300A. Note: Large cable gauges can be split by two or more smaller cables as long as the carrying capacity for those cables meets or exceeds that of the larger cable. Be certain that you're looking at the correct chart we have one for 12V (Blue Chart), 24V (Yellow Chart), & 48V (Green Chart) systems! Next, locate the Power Inverter wattage you’ll be using on the top of the chart and find the point at which both lines intersect that is the cable that you need for your application. Take your round-trip cable length and find it on the left side of the chart. Add together the current draw (amps) of all locks on the same circuit. To calculate amps from watts, take the wattage (W) and divide (/) it by the voltage (V). Access Control System WIRE GAUGE SIZE & DISTANCE CHART For 12V and 24V AC/DC.To calculate watts using amps (A), multiply Volts (V) times Amps (A).If you never plan on using the 10,000W, you should size your cables for 8,000W. This is the BIG question! You may have a 10,000W Inverter, but only plan on using 8,000W max. The AWG table below is for a single, solid, round conductor. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. If the cable from the inverter to the battery is 5 feet, then the round-trip distance is 10 feet (5 feet to the battery plus 5 feet back to the inverter). The AWG - American Wire Gauge - is used as a standard method denoting wire diameter, measuring the diameter of the conductor (the bare wire) with the insulation removed. You’ll need to know what the distance is from the inverter to the battery and back again. This loss is referred to as IR voltage drop. You just need to know the power in Watts (VA), or Amps and the table will show how far you can go in feet for any size wire pair listed. AWG = American Wire Gauge, the national standard for wire sizesĬable Length: What is the Round-trip distance? 24 Volt Wire Length Calculator Quick Overview As electric current flows through wire, there is a loss in voltage.Take a look at the charts below, we have 12V, 24V, and 48V charts. Current carrying capacity is defined as the amperage (A) of which a conductor can carry before meIting either the conductor or the insuIation. In the 2nd chart, we specify the DC wire gauges amp draw ranging from 1 amp to 1000 amps. Answer: Which cables you need are based on – How long the cable needs to be and how many watts you’ll be running. In the 1st chart, we specify the copper and aluminum wire sizes for 12V, 24V, and 48V voltages and wattages ranging from 1 watt to 5000 watts. ![]()
