Based on these factors you’ll be able to pick the best gauge wire for the job. We’ve found solid 20 and 22 AWG wire options, which work for most systems that use single color LED lights.
What size wire do I need for a LED light bar?
72 watts @ 12 volts is 6 amps, so I’d probably use a 10 amp fuse. The wire size you need depends on the length of the run. For a run of up to 15′ you could use 14 gauge wire.
Can I use 16 gauge wire for lighting?
16-gauge are used for light-duty extension cords supporting 13 amps. 14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps. 12-gauge are used in kitchen, bathroom, outdoor receptacles, and 120-volt air conditioners supporting 20 amps.
Can I use 14 gauge wire for lights?
It’s OK to wire a 15-amp light circuit with a 14-gauge wire to save a bit of money and make the wiring job a bit easier. … You must also use a 12-gauge wire when connecting an outlet rated for 20 amps, as many GFCI outlets are, even if the appliances you plug in are rated for only 15 amps.
What size fuse should I use for LED lights?
75mm is good for about 7.5 amps max. I generally like to have at least 100% extra rating so a 3 amp fuse max is what i would use. This should be plenty for 4 leds. If you have working leds but blow a 10A fuse i think your wiring needs checking and you will probably find your fuse is directly across the battery.
Can you use speaker wire for LED lights?
Yes you can(with the appropriate current rating being taken into consideration, as discussed elsewhere), but speaker wire is more expensive than normal wire “because of better audio properties”, so why not just get some cheap old regular wire..
Can I use 18 gauge wire for LED lights?
Most people would likely recommend using a solid core 18-gauge wire for your LED lights. … This wire size is capable of handling much more than your average system. If you are going to install several 12v LED lighting with dimming options, you might want to grab wiring connectors, which can help you with your wiring.
What wire do you use for 12v lights?
Going by what this table says for 12v 8Amps you need a 14 gauge cable. If you where to buy everything 24v you’d only need to transport ~4Amps of power and thus only need a 22 to 20 gauge cable.
What wire do I use for lights?
The following NEC regulations apply to Romex conductors:
|Wire Gauge or Type||Rated Amperage||Common Uses|
|14-2 Romex||15 A||Lighting Circuits|
|12-2 Romex||20 A||Lighting and Outlet Circuits, refrigerator|
|10-2 Romex||30 A||Electric water heater, baseboard heaters|
|10-3 Romex||30 A||Electric Clothes Dryer|
Is it OK to mix 12 and 14 gauge wire?
Anyway, the first subject is a bit touchy because it makes it difficult to perform an inspection when all of the wires coming into the panel are 12 but many of the circuits have 14 in them too. There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire.
How many LED lights can I put on a 15 amp circuit?
Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.
Can 14 gauge wire carry 20 amps?
You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals.
What kind of fuse do I need for 12v?
There are 3 types of 12v fuses I recommend. They are Spade Fuses, ANL fuses, and Re-settable Breakers. Spade fuses are the fuses that you’ll commonly find in your car’s fuse panel and are typically for items run out of your distribution block and less than 30 amps (in our case.
Do I need a relay for LED lights?
A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. … If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.
How many watts can a 3 amp fuse take?
Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red). For example: 3A Fuse – Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron.
