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 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 is a 16 2 wire?
The 16/2-GY is a 16 gauge 2 conductor stranded multi-conductor cable designed for security and low power applications. It is a power limited circuit and communications cable commonly used in control, signaling, security, communications, intercom/PA, sound/audio, and nurse call installations.
What voltage is 18 gauge wire rated for?
The voltage depends on the specific wire – some 18 AWG is designed for low-voltage applications and is only insulated for perhaps 100 volts, common ELECTRICAL 18 AWG normally has 300 volt insulation (keep in mind that this is PEAK voltage, 300 volts PEAK is a hair over 200 volts RMS on a pure sine wave), some special-.
Can you use 18 gauge wire for 120v?
The resistance of 18 AWG copper wire is 0.0064 ohms per foot. If you apply 120v from a sufficiently robust power supply end to end on a one foot long piece of such wire 18,750 amps will flow until the wire gets hot enough to melt.
How many amps can 18 AWG handle?
A conservative estimate for several feet of 18 AWG (American Wire Gauge) wire is 16 Amps. However, length plays an important role in the amount of Amps a wire can carry. If you have only 12 inches of wire, the 18 gauge wire can handle more than 16 Amps.
What voltage is thermostat wire rated for?
A Class 2 power-limited cable for use in thermostat controls applications, bell and alarm systems, not to exceed 150 volts when installed as specified by the National Electrical Code® (NEC) and other applicable standards. Thermostat wire is sunlight resistant.
Is doorbell wire and thermostat wire the same?
Thermostat wire is typically larger 18 gauge, bell wire is smaller 20 gauge, while phone cable is typically smaller 24 gauge. All three can be used for doorbell and other low voltage applications (structural wiring).
What type of wire should I use for outdoor lighting?
Common wires for landscape lighting are 10-, 12-, 14-, or 16-gauge wires. We recommend 12-gauge or 10-gauge wire for long distances. This is to prevent voltage drop. The further you get from the transformer and its power supply, the more resistance occurs in the circuit which causes the voltage to decrease.
How far can you run 14 2 low voltage wire?
Wirefy 14/2 Low Voltage Landscape Lighting Wire – Outdoor Direct Burial – 14-Gauge 2-Conductor 250 Feet.
What is the difference between 14 2 and 16 2 landscape wire?
14 gauge wire is bigger/thicker than 16 gauge.. wire gets bigger as the # gauge smaller.. The larger the number the thinner the gauge of the wire.
Is all 18 gauge wire the same?
The common denominator with each lead wire is the amount of electricity that can travel through a copper wire as thick as 18 awg. The differences are voltage, environmental temperature and possibly weather or moisture that could damage or puncture the insulation.
What size wire is 18 AWG?
Share: GAUGE SWG DIAMETER (Inches) AWG DIAMETER (Millimeters) 12 Gauge Wire 0.1040 in 2.052 mm 14 Gauge Wire 0.0800 in 1.626 mm 16 Gauge Wire 0.0640 in 1.290 mm 18 Gauge Wire 0.0480 in 1.024 mm.
How many watts can 18 gauge wire handle at 120 volts?
Matching Extension Cord to Load Extension Cord Wire Gauges, Amperage Rating, and Wattage Wire Gauge Amperage Rating Wattage Rating #18 5 Amps 600 Watts #16 7 Amps 840 Watts #14 12 Amps 1,440 Watts.
What wire do I use for 120v?
Wire Gauges Household wiring for 120-V circuits is almost always 12- or 14-gauge copper wire, depending on the current load and length of the circuit. The diameter of the metal conductor in a 12-gauge copper wire is 0.0808 inches; of a 14-gauge wire is 0.0641 inches.
What is a 18 4 low voltage wire?
The 18/4P is an 18 gauge 4 conductor stranded plenum multi-conductor cable designed for security and low power applications. This 18-4 plenum cable features bare copper stranded conductors, color-coded conductors, and a white plenum rated (CMP) jacket.
How many amps can each gauge wire handle?
“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”Sep 18, 2017.
What current can 18 gauge wire carry?
Maximum Current For 18AWG Wire The current is measured in amps. An 18-gauge wire can handle 16 amps.
How much current can 16 AWG wire carry?
Amperes Insulation Materials: Polyethylene Neoprene Polyurethane Polyvinylchloride (Semi-Rigid) Kapton PTFE FEP PFA Silicone 16 AWG 19 32 14 AWG 27 45 12 AWG 36 55 10 AWG 47 75.
How many watts can 16 AWG wire handle?
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 type of wire is used for thermostats?
The most common thermostat cabling is 18/5 (18 gauge, 5 conductor), because 5 conductors typically offer enough functions for a modern thermostat/low voltage device.
How do I choose a wire for my thermostat?
Thermostat Wiring Tips The W wire is connected to your heating system. The Y wire is yellow and connects to your air conditioning compressor. The G wire is green and connects to the fan. Rc and Rh: The red wire(s) are the power source for your thermostat.
Can I use 22 gauge wire for a thermostat?
Nest thermostats require wires between 18 and 22 gauge, which is standard for residential heating and cooling systems. Anything smaller than 22-gauge wire could be too thin for a Nest thermostat to detect.
