Identifying the Hot, Neutral, and Ground Wires | ||
---|---|---|

Hot | Neutral | |

Twisted Pair | *plain (no stripe) wire | *striped wire |

Three-Conductor | black wire | white wire |

Plug/Socket | narrow prong/gold screw | wide prong/silver screw |

Also, which plug is hot?

The wide prong on the

**plug**links the threaded base of light bulbs to the neutral terminal (the wider slot) in the receptacle. If the wires are reversed, the**hot**side of the outlet (the side that can deliver a shock) is wired to the threaded socket.Which side of plug is white?

A little hard to read, but the

**left**side says "hot wire" and the**right**side says "white wire". We'll put the black wires on the hot side and the white wires on the**left**side. First connect the ground wire to the green screw at the**bottom**of the outlet.1

## Is the hot wire the common?

The power source, or "feeder

**wire**" is a 2-**wire**cable with a ground, meaning it has one black (**hot**)**wire**, one white (neutral)**wire**and a bare copper ground**wire**. The black**hot wire**from the feeder cable is connected to the**common**terminal on the first switch. Neutral**wires**do not connect to switches.2

## What is the green screw on light switches?

The black (hot)

**wire**goes to the**brass screw**or into the hole in the back of the device on the same side as the**brass screw**. This**wire**is sometimes red. The green or bare copper (ground)**wire**, if the device has one, attaches to the green**screw terminal**on the switch or to the electrical box.3

## What wire to use for 3 way switch?

Feed a length of 14-3 type NM

**cable**(or 12-3, if you're connecting to 12-**gauge**wire) between the two boxes. The 14-3**cable**has three insulated conductors: white, black and red (plus a bare**ground**wire). Connect the wires to the new three-way switches with**ground**screws using one of the two wiring diagrams (Fig.4

## What is the red wire?

The white

**wire**is the neutral, and all other colors are hot. Electricians often use black,**red**or blue**wires**to deliver electricity to a circuit from the main panel. They may use other colors for switch wiring, such as yellow or tan. Orange**wires**frequently are used to interlink smoke detectors.5

## What is the purpose of a three way switch?

Toggling the switch disconnects one "traveler" terminal and connects the other. Electrically, a typical "3-way" switch is a single pole,

**double**throw (SPDT) switch. By correctly connecting two of these switches together, toggling either switch changes the state of the load from off to on, or vice versa.6

## What is meant by common wire?

The

**common wire**in an industrial electrical circuit is the neutral**wire**or ground**wire**. Find out more about the**common wire**in an industrial electrical circuit with help from an electrical contractor with over 25 years of experience in the electrical industry in this free video clip.7

## What is Cu wire only mean?

Switches are marked with different labels to identify ratings, types, and acceptable

**wire**types. If it reads, "use**CU wire only**", the**only copper wire**may be used for the connections, not aluminum. If it says, "CO/ALR", that means that either**copper**or aluminum**wire**installation is allowable.8

## What is the use of circuit breaker?

A

**circuit breaker**is an automatically operated electrical switch designed to protect an electrical**circuit**from damage caused by excess current from an overload or short**circuit**.9

## What is the meaning of Mccb?

MCB means Miniature Circuit Breaker -- it is used for upto. 100Amps in the motor feeders.

**MCCB**menas Moulded case Circuit Breaker -- it is used for. 25oAmps to 800Amps in the motor feeders. ELCB means Earth Leakage Circuit Breaker -- it is used to.10

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

I can do the simple math: 180va (or 1.5 amps) per general use receptacle gives a limit of

**10 receptacles**per 15 amp circuit or**13 receptacles**per**20**amp circuit.11

## How many GFCI outlets do you need on one circuit?

You only need

**1 GFCI**outlet per circuit (assuming it's at the beginning of the line and the rest of the outlets are loads). They are correctly wired in parallel - if they were in series, you wouldn't get the correct voltage at the other outlets when there is any type of load present. It is possible.12

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

For

**20**AMP you have 20A*120V or**2400**watts and 15 AMP you have 15A*120V or**1800**watts. Good Electricians will only plan for**80**% load so you have 1920 and**1440**watts respectively at your disposal per circuit. Next, find out what's on the circuit. To do this, leave the lights on that you want to connect to.13

## How many outlets can be on a 20 amp 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.14

## How many amps does a 1000 watt light use?

A 1000w HPS or Metal Halide light takes

**9 amps**at**120**volts so you can only run one on a wall outlet circuit. A standard dryer outlet is**220**volts and**30 amps**so you can power up to six 1000 watt lights on that circuit.15

## How many amps are in a 1000 watts?

Power is voltage multiplied by current. 1000 Watts can be 250 volts RMS AC x

**4 amps**(i.e. 250 x 4 = 1000). 1000 Watts can be 12 volts DC x**83.3 amps**(i.e. 12 * 83.3 = 1000). It does not matter whether you apply AC or DC, 1kW is 1kW.16

## How many amps are in 600 watts?

amps x volts = watts.

amps x 120 = 600----- 600/120 =

amps x 240 = 600 ---- 600/240 =

amps x 120 = 600----- 600/120 =

**5 amps**.amps x 240 = 600 ---- 600/240 =

**2.5 amps**.17

## How many amps does it take to run a 700 watt microwave?

It's around 6.4 Amps but the exact value depends on your electrical service and whether the manufacturer has stated an accurate power rating. For comparison you can draw about 1600 Watts from a standard wall outlet and that requires a bit less than

**15 Amps**.18

## How many watts is 2.4 amps?

Quick calculation to find watts: Volts * Amps = Watts, so 5V * 2.4 amps =

**12 watts**.19

## How many watts is 15 amps?

The circuit and circuit breaker that you tripped have a capacity of 15 amps, or

**1,800 watts**(15 amps x 120 volts =**1,800 watts**). The lights drew 360 watts, or a measly 3 amps (360 watts divided by 120 volts = 3 amps)—well within the capacity of your 15-amp system.
