Ok, so basically, it just means **there are 5 wires inside**. So in an extension cord, it would be x number of wires that are each y gauge. Thanks! The other time you see fractions is on very heavy gauge wire, but it’s only with zero on the bottom like 1/0, 2/0, and is normally pronounced one-ought, two-ought, etc.Nov 29, 2017

## Are 12/3 or 12 2 wires better for outlets?

Quote from the video:

Quote from Youtube video: *12 2 or 12 3 wire. This is 12 3 wire and what makes it 12 3 is that you got three wires other than the ground. And 12 2 means you got two wires other than the ground. So if you hear 14.*

## What do the numbers mean in electrical wiring?

Cable by the Numbers

An electrical cable is classified by two numbers separated by a hyphen, such as 14-2. **The first number denotes the conductor’s gauge; the second denotes the number of conductors inside the cable**. For instance, 14-2 has two 14-gauge conductors: a hot and a neutral.

## How do you read a wire size?

Wire gauge sizes are represented through numerical values, AWG 4/0 through AWG 40. **The lower the number assigned to a wire the larger its diameter; the higher the number the smaller its diameter**. AWG stands for American Wire Gauge.

## What are 12 3 wires used for?

ROMEX® 12/3 wire is **used in buildings for circuits that use higher amperage than the standard 20 amps**. Most people are not familiar with this type of wire because it is used to hook up heavy-draw appliances such as water heaters and central air conditioning.

## How many outlets can be on a 15 amp circuit?

8 outlets

Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a **maximum of 8 outlets** for a 15 amp circuit.

## Can you use 12 gauge wire on a 15 amp circuit?

With 12 gauge, you need to use the screw terminals. **You can use 15 amp outlets on either 15 or 20 amp circuits**. 12 gauge wire is the minimum for 20 amp circuits. 14 gauge wire is the minimum for 15 amp circuits.

## What size wire can handle 30 amps?

10-gauge wire

“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].”

## What do the numbers 14 2 mean when we are talking about electrical wire?

14-2G: **Cable contains two insulated wires plus a ground wire**; the wires are 14-gauge. 14-3G: Cable contains three insulated wires plus a ground wire; the wires are 14-gauge. 12-2 w/G: Cable contains two insulated wires plus a ground wire; the wires are 12-gauge.

## How do you read wire markings?

If the conductor material is either aluminum or copper-clad aluminum, the product, tag or carton markings (depending on the product category) identify the conductor material. These markings will appear as **“AL,” “ALUMINUM,” “AL (CUCLAD),” “ALUMINUM (COPPER-CLAD),” “CU-CLAD AL” or “COPPER-CLAD ALUMINUM.”**

## Can I use 14 3 wire for outlets?

Quote from the video:

Quote from Youtube video: *You can also use 14 3 wire if you are installing multi-branch circuits meaning you are using the black wire for phase a and the red wire for phase b.*

## Can I use 14 gauge wire on a 20 amp circuit?

NEC 240.4(D)(3) states that 14 AWG must be protected at 15A. **You can not use 14 AWG anywhere on a circuit that has a 20A breaker**.

## How many receptacles can be on a 20 amp circuit?

The answer to the question how many outlets on a 20 amp circuit is **ten outlets**. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.

## Can I put outlets and lights on the same circuit?

**Generally a properly wired home should have dedicated lighting circuits that are apart from receptacles**. Overloaded neutrals are fire hazards.

## How do I know if my outlet is 15 or 20 amp?

Quote from the video:

Quote from Youtube video: *And again it has a t-shaped neutral slash so it can receive a special 20 amp plug in addition to the standard 15 amp plug. However. Your 15 amp plug receptacles.*

## How many LED lights can be on a 15 amp circuit?

Assuming a 60 watt light, you can put **up to 24 lights** on a 15 amp breaker. If you are using low-wattage LED bulbs, an LED bulb using 10 watts, you can install up to 150 bulbs on a single circuit.

## How many Amps does a microwave use?

The microwave ovens consume power at a rate of 650– 1200 watt, which equates to a current of around **10 Amps**.

## How many LED lights can you put on one switch?

The load of the lights determines how many you can have. A regular 15A circuit can have up to 1400W of lights connected, or one 1400W light or 14 100W light bulbs. Most homes allow for **23 to 40 60-watt bulbs or 280 to 480 5-watt LEDs**.

## How many outlets can you have on a circuit?

One rule of thumb is to assign a maximum draw of 1.5 amps to each receptacle, which allows for **10 receptacles on a 20-amp circuit**.

## Can I run 15 amp outlets on a 20 amp breaker?

The amperage of the outlet must never exceed the amperage of the circuit. According to National Electrical Code, **only a 15-amp or 20-amp electrical receptacle can be installed to a 20-amp circuit**. A 15-amp receptacle may also be installed on a 15-amp circuit.

## What happens when you put a 20 amp receptacle on a 15 amp circuit?

First off, connecting a 20 Amp load to a 15 Amp circuit will **overload the circuit but shouldn’t cause a fire because the 15 Amp breaker will trip**. A 20 amp GFCI doesn’t pose any threat just by being there.
