How do I choose a DC cable size?
How do I choose a DC cable size?
Cable Sizes: Choosing the right one for a DC Circuit
- A Locate the CURRENT IN AMPS of your appliance across the top of the chart.
- B Find circuit LENGTH IN FEET along the left side of the chart.
- C Select the CIRCUIT TYPE.
- Critical DC circuits, with 3% allowable voltage drop, include.
How far can I run 12v DC?
12V DC Power Drop / Max Cable Distance Chart
24 AWG | 12 AWG | |
---|---|---|
DC 300mA | 72 feet | 1,169 feet |
DC 400mA | 54 feet | 877 feet |
DC 500mA | 43 feet | 701 feet |
DC 750mA | 28 feet | 467 feet |
How much voltage drop is acceptable 12V?
Conductors in electrical systems should not be sized with voltage drops exceeding 3%. For a 12V system the maximum voltage drop should be less than (12 V) x 3% = 0.36 V.
How long can a 12v cable be?
12V DC Power Drop / Max Cable Distance Chart

How long can a 12 volt wire be?
Maximum length of copper wire with 2% voltage drop. By increasing the size of the wire to gauge #2 (33.6 mm2) the maximum length is limited to approximately 32 m.
Can I use normal cable for 12V?
So to answer your question as to is there a specific 12v cable, the answer is NO. That said the convention is about colours in modern day. The Red and Black figure of 8 type of cable is generally used for 12-24v power supply.
How do I choose a cable?
Cable size selection is based on three main factors:
- Current carrying capacity.
- Voltage regulation.
- Short circuit rating.
