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.
