What size wire should I use for LED light bar?
18-gauge wire
Most people would likely recommend using a solid core 18-gauge wire for your LED lights. The cost difference between this wire size and a much smaller cable is negligible, and 18-gauge is about as big as you can go if you would like your wires to fit into most holders or terminals.
Can you use 22 gauge wire for LED lights?
A reasonable rule of thumb is that the number of lights X the length of the wire run should be no greater than 1000 when using 22-gauge wire and it should be no greater than 1600 if using 20-gauge wire. This rule of thumb will allow for a maximum voltage drop of . 6 volts.
How many amps does an LED lightbar draw?
The LEDP3W-36X2 LED light bar from Larson Electronics produces 8,208 lumens of bright light while drawing only 108 watts @9 amps from a 12 volt electrical system.
Is 16 gauge wire good for LED lights?
True 16 AWG LED strips extension cable from TyumenDirect that is ideal for all single color LED strip light, low voltage single color led strip, light bulb, lamp. It is widely used for various DC electrical hookups, low voltage cables, 12V DC, 24V DC, low-loss in-home or car stereo installs.
What gauge wire should I use?
Why Wire Gauge Is Important
| Wire Use | Rated Ampacity | Wire Gauge |
|---|---|---|
| Low-voltage lighting and lamp cords | 10 amps | 18-gauge |
| Extension cords (light-duty) | 13 amps | 16-gauge |
| Light fixtures, lamps, lighting circuits | 15 amps | 14-gauge |
| Kitchen, bathroom, and outdoor receptacles (outlets); 120-volt air conditioners | 20 amps | 12-gauge |
How many amps does a 12V LED light bar use?
IE 120 watts divided by 12 volts = 10 amps.
How much current does a 12V LED draw?
In electrical terms, we now know that at 12V, this LED strip will draw about 24 Watts per reel (5 meters), or about 2.0 Amps.
Can I use 14-gauge wire for lights?
As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.
What size wire is needed for 10 amps?
16
For a maximum of 10 amps, you’ll need a wire gauge of 16.
How many DC amps can 12 gauge wire?
Maximum current (amps) in a 12V electrical circuit vs. size (AWG) and length of wire.
| American Wire Gauge (#AWG) | ||
