It’s safe to do so and there is no limit (in terms of safety) on the cord length.

Can I use 18 gauge wire for a lamp?

Lamp Cord Requirements





The 18-gauge wire inside a lamp cord is rated for a maximum current draw of about 5 amps. That’s more than enough for a typical 120-volt lightbulb — or even several of them.

How many watts will 18 gauge wire handle?

18-gauge automotive wire can handle anywhere between 3 and 15 amps, depending on the distance (12.2 ft to 2.4 ft). The shorter the wire, the more current it can handle.

Can you use 18 gauge wire for LED lights?

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.

What is 18 AWG wire used for?

18-gauge are used for low-voltage lighting and lamp cords in 10 amps. 16-gauge are used for light-duty extension cords supporting 13 amps. 14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps.

What size wire do I need for a light fixture?





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.

Can I use 18 gauge wire for outlet?

You can run 120 volts through an 18 gauge wire, but it also depends on what accessory is being powered and the proper insulation of the cables. Thus 18-gauge wire is relatively safe for wiring in the home.

How far can you run 18 gauge wire?

For a rough rule of thumb, 18-gauge is good for 750 feet, if you are operating one valve at a time.

How many amps can 18 gauge wire handle at 120 volts?

The 16 amps maximum for 18 gauge wire is a conservative estimate for several feet of wire.

What diameter is 18 gauge wire?



about 1 mm

A solid round 18 AWG wire is about 1 mm in diameter.

Is all 18 2 wire the same?

When a wire is labeled as 18-2, it means that it is 18-gauge thickness (AWG) with 2-conductors (inner wires). You can generally swap out 18-gauge wire with slightly thicker or thinner wire. If you need a longer wire run, you might use the thicker 16-gauge wire.

What is a 18 AWG extension cord?



The 18 AWG (American Wire Gauge) pure copper conductor transfers maximum power. This cable operates on 125 volts / 10 Amp power with a max of 300 volts. The 10 Amp high capacity means these cords can be used in any room in the house, even the kitchen and the laundry room.

What gauge of extension cord do I need?

Recommended wire gauge for extension cords

Larger numbers mean smaller wires, which in turn means it can carry less power. A cord measuring 14 AWG is the thinnest we recommend—and at lengths of only 25 feet or shorter—and the much thicker 10 AWG is likely the thickest gauge you’ll find in an extension cord.

How do I know what size extension cord I need?

So, if your equipment requires 15 amps, it must get 15 amps. To properly size an extension cord so your equipment is getting enough power, consider the distance you will run the cord and the amps that your equipment needs to run (found on cord). When using 100 feet extension cords, you’ll need a: 16 Gauge for 1-10 Amps.

How many watts can an extension cord handle?



As the cord gets longer, the current carrying capacity of the cord gets lower. For example, a 16 gauge extension cord less than 50 feet in length can power a 1625 watt (W) appliance. A 16 gauge cord that is longer than 50 feet in length can only power an appliance up to 1250W.

What happens if you overload an extension cord?

Extension cords can overheat and cause fires when used improperly. Overheating is usually caused by overloading or connecting appliances that consume more watts than the cord can handle. Damaged extension cords can also cause fires.

What is a 16 gauge extension cord good for?

Sixteen-gauge cords are low wattage and are intended for use with small appliances such as portable fans, alarm clocks, table lamps, or floor lamps (note: an electronic device such as a TV or computer should be connected to a surge protector).

How many watts can a single outlet handle?

1,500 watts



How Do You Know How Many Things You Can Plug Into One Outlet? As a rule of thumb, it’s safest to stick to a maximum load of 1,500 watts per outlet or circuit. The number of things you can plug into one outlet depends on the wattage of each device or appliance you want to plug in.

What are three warning signs of an overloaded electrical circuit?

Signs of Overloaded Circuits

  • Dimming lights, especially if lights dim when you turn on appliances or more lights.
  • Buzzing outlets or switches.
  • Outlet or switch covers that are warm to the touch.
  • Burning odors from outlets or switches.
  • Scorched plugs or outlets.

What happens if you plug too many things into an outlet?

An overloaded power outlet can cause a tripped circuit breaker, increase your risk for electrocution, or start a fire.
