L and N are two terms that are used in electrical wiring to describe where an item is located. These terms have many different meanings when it comes to giving information about an item.
L is for locate, where an item is located in the electrical wiring. A locate is a mark on the wire that identifies where the wire goes and what it connects to.
N is for non-connect, where an item does not connect to the wiring, but may be connected by the wiring. Non-connecting items may be filters, lighting fixtures, or similar items that do not physically connect to the power source but can transfer power through them.
This article will talk about some of the more common terms used in electrical wiring and how they affect your job as an electrician.

Neutral
What is neutral?neutral means different thing in electrical wiring. Depending on what type of wiring you have, there are different terms for the neutral connection.
For instance, box-type connections have a tab that goes on the opposite side of the wire from the hot and ground wires. This tab is called a neutral tag.
The other kind of neutral tag goes on the hot wire and none on the ground. These are private tags used by construction workers or people who want to preserve the privacy of the home.
As far as why it is called neutral, it has nothing to do with its appearance.
Parallel
When connecting two electrical wires, parallel means that they should be connected side by side. If one is connected, the other must be also.
Parallel wiring is good as it allows you to see what is on each wire. If one is positive and the other negative, you can determine if they are high or low voltage, assuming they are wired up correctly.
If one wire is positive and the other negative, you can determine if they are high or low voltage only if you cut the positive wire. If you do not have a wire cutter, you can use a potentiometer to test if the negative has been disconnected.
Potentiometers are devices that allow you to measure how much force it takes to rotate or shift a given piece of hardware. In this case, we want to know if we have removed the negative lead from the battery because that would require a potentiometer.
Series
When there is a sequence of wires or lines that have to be connected, those lines or wires should be connected by creating a “series” of connections.
When placing a new circuit in place, the last component added to the circuit must be a single connection point. This is called an electrical outlet and determines whether or not a new power source needs to be inserted into the system.
There are several possible series connections, one of which is called a electricity cable. These are typically used when installing an audiovisual system since it requires two cables- one for power and one for data.
There are also possible parallel connections, however, these must be examined more closely due to their higher risk. One potential cause for noncompliance is if parallel circuits are not legal in the jurisdiction.
Circuit
Circuit is a term that refers to a uninterrupted or closed-loop electrical system. There are many kinds of circuits, such as power, illumination,Display,control,communication,alarms and outlets. Most circuits have one or more switches and receptacles to control electricity flow.
Switches are used to turn on or off electrical appliances such as lights and ovens. Switches can be on or off-base style which means that you must insert a piece of metal into which the switch connects to be able to turn the appliance on or off.
On-base style switches typically have an ON/OFF knob inside of them so that you can change the direction in which the switch is turned. These must be inserted from the top down so that they are connected to the right side of the wall box.
Ground
When a device needs to be connected to the main power source, it typically needs a ground connection. This means that it can safely be plugged into the wall and processed as electricity.
Most devices are compatible with a 100-240v standard, so no problem! But some do use an American standard of 120v, which is odd. If you have a jewelry box or some other item you store belongings in when not in use, then this would be useful for storing items without risk of electric shock or breakage.
Electronic devices have problems with hot and cold temperatures alike, so having a reliable way to connect the two is important. The safest way is through a short length of circuit-through-the-wire called a ground wire. These are typically exposed when there is an electrical circuit needed between them.
Power
Without power, you cannot do anything! So, this is a big one. You need to know how to wire a house!
There are different ways to power. Some houses have electricity, and others do not. There are wired homes and un-wired homes. Many times, when looking at a home, it is determined by what kind of equipment they have on their property- did they have electricity at the house construction time?
If someone has no electricity at all, then they may be able to use roof power or batteries to keep the lights on and the fridge working. If someone hasElectricity!- both positives and negatives of this type of power are studied in depth!.
These types of powers can be voltage, voltage/frequency, continuity, or continuity/voltage. Each one adds or takes away from the total power needed for any project.

Amperage
Amperage is a big part of electrical wiring. What amperage and how much amperage! There are also measurement units for amperage. It is not common to see a wiring diagram with two boxes labeled Amps and Volts, for instance. Those are for computer hardware, not electricity.
There are three common measurements of power: A A, B, and C power. The different values indicate where the power comes from (namely, 220-240V), where it goes (110-120V), and what it does (generally, a light turns on or off).
Power is an important topic to understand because things can go wrong when too little or too much power is present.
