RoHS Compliant. The ends of the cable are often terminated with a Battery Terminal or Copper Cable Lug. The internal copper stranded core is highly conductive maximizing current flow while still being highly flexible. Rated for low voltage and battery use up to 60 volts DC and 25 Volts AC. Made from 133 strands of 20 gauge 99.9% pure copper and covered in a rugged PVC insulation available in red or black. When using battery cable in low voltage electrical systems such as 12 volts, the total length of both the positive and negative cables have to be considered when determining amperage capacity for your electrical system. The outside diameter of the cable is approximately 0.605 inches. Failing to use properly sized wires may lead to overheating and melted circuitry. Caution Ensure your wires can handle the current draw for your devices. The n gauge wire's cross sercional area A n in kilo-circular mils (kcmil) is equal to 1000 times the square wire diameter d in inches (in): An (kcmil) 1000× dn2 0.025 in 2 × 92 (36-n)/19.5. Correct sizing typically depends on wire length, total current, and ambient temperature. A few sources exist for Teflon wires, aircraft supply, surplus sometimes, even a few racing places are starting to sell it. See our Wire Size Calculator for an interactive chart to help find the right wire for your project. Sometime you may see wire called PTFE, PTF for Teflon as well. 2/0 battery cable can comfortably handle 200 amps at a cable length of 15 feet. Typical temperature range for Teflon is -60C to 200C (-76F to 392F) and Tefzel is -70C to 150C (-94 to 302F). A 4 to 5% loss is acceptable between batteries and lighting circuits in most cases.2/0 Gauge (American Wire Gauge) Battery Cable is designed for higher amperage applications with a maximum voltage rating of 60 volts DC. Wire Loss Tables for 12 VDC and 24 VDC Systems Use this table to determine the maximum. Do not exceed the 2% drop for wire between PV modules and batteries. Note that we stock battery-to-inverter cables in 2, 2/0 and 4/0 AWG. You can go twice the distance where a 4% loss is acceptable. Use these tables to determine the maximum distance one-way in feet of various gauge two-conductor copper wire from power source to load for 2% voltage drop in 48-volt and 120-volt system wiring. Note that a 24 VDC array can be placed much further from the battery bank than a 12 VDC array of the same size due to the lower current. A 4% to 5% loss is acceptable between batteries and lighting circuits in most cases. Do not exceed 2% drop for wire between PV modules and batteries. This should work for most 12-volt devices. The table is based on a 10 loss of voltage on a pair of wires. 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. If a 4% loss is acceptable then the distance can be doubled. The table below is for 12-volt ac or dc devices only. Use this table to determine the maximum distance from power source to load for 2% voltage drop. Wire Loss Tables for 12 VDC and 24 VDC Systems Note that we stock battery-to-inverter cables in #2, 2/0 and 4/0 AWG. Ode below for NEC code requirements when going transformer-less: Please click the Going Transformer-less Electrical Contractor Magazine article by Mark C. Larger cables may be necessary if the distance from the inverter to the battery is greater than 10 feet. Smaller cable sizes can be used if fuse or breaker size is reduced but this can cause problems if the inverter is running near its maximum output wattage. Use this table to decide cable size and fuse or breaker size for common inverter models. Recommended Inverter Cable and Overcurrent Protection The versatile Powerpole® and SB® connector series invented by Anderson Power Products meet a wide range of power connection needs. National Electrical Code (NEC) allows rounding up cable ampacity to next size standard fuse or breaker.įor ambient temperatures above 30☌ (86☏), multiply the allowable ampacities shown at right by the correction factor listed under the insulation temperature rating below. Properly sized wire can make the difference between inadequate and full. The table below shows allowable ampacities of conductors (wires) in conduit, raceway, cable or directly buried, in an ambient temperature of 30☌ (86☏). Handy tool for sizing wires and cables for 12-volt, 24-volt, and 48-volt systems. Establish a Solar Panel Decommissioning Program
