Select the wire conductor material either. That means you will need a 1 AWG wire for 100 amps since it has 130A ampacity. The best way to gauge how many solar panels you need is to understand and define the power load needed from this system.

Circuit Voltage VDC 12. We find a wire gauge for which the ampacity is higher than the fuse size. This DC wire size calculator will help you calculate the wire gauge automatically.

If the wire gauge is OK to use it. Input what percentage voltage drop is allowable. Using load_current and length we compute the wire gauge that meets the chosen voltage drop.

To use the calculator enter the Maximum Current in Amps of the circuit and the Length of the Wire and operating Voltage. That means the calculator can be a simple DC wire size calculator all the way up to an AC three-phase tool. Load Current Amps.

For a 48V system multiply the distance taken from the 24V chart by 2. The voltage drop V in volts V is equal to the wire current I in amps A times 2 times one way wire length L in feet ft times the wire resistance per 1000 feet R in ohms Ωkft divided by 1000. Please ensure you cross reference and refer to manufacturers specifications.

Any wire size or circuit protection tentatively selected with this tool should be reviewed for adequacy before installation by a professional applying the applicable industry standards. The chart and the formula on this page are provided to help you in selecting the best cost power loss compromise.

If you may provide instant DC. Circuit Voltage VDC 12. The recommend gauge is the result of applying ABYC Standards factors allowable voltage drop and any additional derating factors.

The dashes represent currents which cannot be handled by the. 70 for 2-3 conductors 60 for 4-6 conductors 50 for 7-24 conductors 40 for 25 conductors Plus a multiplier of 85 for engine room heat. Load_current fuse_size125 it is generally accepted that a fuse must be at minimum 125 the size of the load current.

Blue Sea Systems expressly disclaims responsibility for any use of this calculator that results in inadequate wire size or circuit protection. Wire gauge calculator Voltage drop calculations DC single phase calculation. From this chart we see that 18 AWG wire has an ampacity of 14A copper wire at average 75C.

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. Ad Lowes Has All Of The Essentials You Need To Tackle Your Electrical Project. Printable Chart - Voltage Drop at 12 Volts Double the distances for 24 volt.

Ampacity is based on the National Electrical Code USA. If you want to limit your losses to 2 simply divide the distance by 25. Closest American AWG gauge.

The wire sizing guide below provides the minimum wire size needed to limit voltage drops to 5 at a given distance in a 12V or 24V system. Sources and references are provided at the bottom of the page. Please refer to someone competent and qualified if you are unsure.

Discover the Crutchfield Difference. 52- Wiring your 12v Refrigerator. For 100 amp service you will a wire with at least 125A ampacity.
