# What is the red wire in 14 3?

## What is the red wire in 14 3?

Normally, when using 14–3 cable, one wire, (black) is used for the ‘hot’ wire, and one, (white) is used for the return or neutral wire. The third wire, usually red, is used for any other purpose, such as for the extra wire in a three-way switch circuit.

### What is 4 wire Romex used for?

Electrical junction box with multiple circuits. Connecting a 4-wire and a 3-wire circuit at a junction box is used to connect two 120-volt circuits to one 240-volt line. This configuration is used most often for large lighting arrays.

How many lights can you put on 14 gauge wire?

14 gauge wire will carry 20 amps. (But see NEC, the National Electrical Code). A 100-watt- equivalent LED light consumes about 13 watt, or about 0.11 amps. So, that’s about 180 such lamps.

How far can you run 14 3 wire?

As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 percent voltage drop….For 120-volt circuits:

14 AWG 50 feet
8 AWG 76 feet
6 AWG 94 feet

## What is 14 3 wire used for?

A rating of 14/3 refers to the gauge of the wire and how many conductors are in the cable. In this case, the wire gauge is fourteen (lower numbers mean larger wires) and the three indicates that there are three conductor wires in addition to a non-insulated ground wire.

### What are the 3 components of an electrical circuit?

Electrical and electronic circuits consist of connecting together many different components to form a complete and closed circuit. The three main passive components used in any circuit are the: Resistor, the Capacitor and the Inductor.

What are 3 types of electrical circuits?

Types of electrical circuits. There are three main types of circuits encountered in a domestic situation. They are ring circuits, radial circuits and lighting circuits.

What is 14 gauge electrical wire?

14 gauge (“white”) wire is used for 15amp circuits and is what you will probably use for everything you are doing. 12 gauge (“yellow”) wire is used for 20amp circuits. In a typical home these are used in the kitchen and sometimes for dedicated window AC unit circuits.
