A Guide to Electrical Supplier Products and Materials

Electricity is the core of all modern operations; it is essentially the driving force behind all our activities in this modern world. In this day and age, virtually everything that is produced and consumed is with the use of electricity—so it goes without saying that selecting and purchasing first-rate quality products from an electrical supplier is of utmost importance. Everything from outlets to receptacles to switches and plates to conduits, wires, fittings, and fuses are necessary tools and equipment that need to be reliable.



Basic Electrical Safety Measures for Home and DIY Consumers

Basic Electrical Safety Measures for Home and DIY Consumers

Although electricity definitely provides many advantages that keep our contemporary world afloat, it also carries with it many destructive and even lethal tendencies when something goes wrong.

Before we dive deeper into all the products, materials, and aspects that have to do with electrical suppliers, let’s take a look at some of the primary safety tips when handling and performing general electrical installation procedures:

  1. When you are installing receptacles, the power that connects to it should always first be turned off or cut from the source. You have to be sure that you are using the correct wiring and that all the connections are securely tightened. Strip off only what you need, strictly leaving minimal copper exposure. You do not have to necessarily screw in the cover before testing, but you should always make it a point to place it on the wall as though you were about to already fasten it in place.
  2. Most electrical codes require GFCI (ground fault interrupter protection) receptacles as a precautionary measure for wet areas in such places as kitchens and bathrooms. These are areas where electrical safety is most critical. Make it a point to immediately replace these receptacles with another GFCI when needed.
  3. Never add a power strip or extension cord to a daisy-chain power extension. This leads to overloading that could potentially cause fires.
  4. Structural wiring repairs that are complex and intricate in nature should never be attempted by somebody without proper training and background. It is a mistake to risk serious injuries, fires, or power outages just to avoid the paid services of a professional. Find a highly reputable and licensed electrical for matters of this concern.


When it comes to electrical suppliers, the electrical materials that they provide are fundamental elements or parts that are used in the making or performance of any electrical construction project or operative machinery. These vary from small and simple house circuitry to something as large as industrial plants.

Let’s take a look at some of the main categories and materials that electrical suppliers cater to:


Electrical Conduit and Conduit Fitting

A tube that carries electrical wiring for communications or power. A conduit is constructed with rigid steel: a lighter steel known as IMC or intermediate conduit, EMT or thin wall conduit, PVC or plastic aluminum, or PVC-coated. Conduits for electricity range from 3/8 to 6 inches in size.

Conduit fittings are part of what is utilized in connecting or adapting other parts of conduit carrying electrical power or communication wire. These can either be indoor or outdoor.


Electrical Wires and Cables

This type of wiring is classified as either drawn metal, copper or aluminum that drives electricity through an electrical circuit. These wires can be run overhead, underground, or through a conduit open.

They are protected by design with a jacket or cover depending on the usage. Electrical wires and cables can be as flexible as extension cords and can be as small as 26 gauge to as large as 2000 MCM.


Circuit Breakers

Circuit breakers are devices that automatically interrupt or stop the flow of an electric current as to protect against overload or shortage.


Electrical Connectors

Electrical connectors are responsible for connecting or adapting one part to another. These also range in size from 3/8 to 6 inches. They too can be either indoor, outdoor, corrosive protected, or explosion proof in design.


Electrical Boxes

An electrical box is an enclosure used for purposes such as pulling, connecting, or terminating an electrical circuit. Electrical boxes are also available as either indoor or outdoor. They can consist of steel, aluminum, plastic, stainless steel, or cast iron. Their design properties can also be corrosive protected or explosion protected.



Lugs are electrical connectors that terminate the electrical circuit. They are made with either copper, aluminum, or bronze. Lugs can be mechanical or set screw, compression or chimp, solder, weld, or clamp type.



Applications of an AVR

Applications of an Automatic Voltage Regulator (AVR)

One of the most common products that are provided by an electrical supplier is the automatic voltage regulator. This is basically used to regulate voltage—it takes the fluctuating voltage and transforms them into a constant voltage. The fluctuation in the voltage primarily occurs because of the variation in load on the supply system—this can damage your power system.

The variations in voltage can be controlled with the installation of control equipment at different places near the transformers, generator, feeder, etc. The voltage regulator is provided in more than one point in the power system for controlling the voltage variations.


Working Principle

An AVR works on the principle of detecting errors. The power voltage of an AC generator obtained through a potential transformer and is rectified, filtered, and compared with a reference. The central difference between the actual voltage and the reference voltage is known as an error voltage. The error voltage is augmented by an amplifier and then supplied to the main exciter or pilot exciter.

Amplified error signals ultimately control the excitation of the main exciter through a buck or a boost action controlling the fluctuation of the voltage. Exciter output control leads to the controls of the main alternator terminal voltage.


Application of the Automatic Voltage Regulator

Now that we have an adequate understanding of how an AVR from an electrical supplier works, let’s take a look at its main functions:

  1. Controls the voltage of the system and has the operation of the machine near to the to its steady state stability.
  2. Divides the reactive load between alternators operating in parallel.
  3. Reduces the overvoltage that occurs due to sudden loss of load in the system.

Increases the excitation of the system under faulty conditions so that the maximal synchronizing power exists at the same moment of the fault’s clearance.



Electrical Outlets and Switches

If you are looking to install electrical outlets or switches in your home or office, electrical suppliers are fully-equipped with products for all your electrical wall mounting needs. Whether its duplex style, combination or rotating options, electrical suppliers are well-versed in their appropriate functions.


Electrical Switches

Electrical switches are available in different types and styles. For example, illuminated switches are designed to be easily located in the dark. Occupancy sensor switches automatically light a room when movement is detected.


Electrical Receptacles

Electrical receptacles are fundamentally the same as electrical outlets. Receptacles provide a source of electricity when a device is plugged into the wall. To name a few, duplex rower receptacles, 360-degree rotating units, USB versions, and many others are sure to fit your power needs.



Types of Wall Plates and How to Use Them

Types of Wall Plates and How to Use Them

Wall plates are another primary product that electrical suppliers provide. Wall plates serve as an entrance into the wall for various cables and wires. They also cover electrical outlets and wall switches, and can even be used as wall plates for A/V and data, offering lots of versatility!

Here is an overview of the 4 types of wall plates and their function:


Electrical Wall Plates

In this day and age, the basic electrical wall plate has evolved into variations that come with weatherproof outlet cover that protects it from any wet, cold, or extreme conditions. There are now also electrical wall plates with specific labeling.


Cable Entrance and Exit Wall Plates

Whether it’s a home theater system or network system, bulk cable wall plates allow you to run several cables through one hole at a time, while exhibiting a clean and neat look. There are also more complex options that allow for you to have power access while managing multiple cables all at once.


Keystone Wall Plates

These can accommodate for up to six modules and various inserts for all your voice, data, and audiovisual needs all in one spot with easy cable identification for convenience and efficiency.


Audio Visual and Data Wall Plates

These are typically used for large places such as hotel rooms, but they can also be customized for your own home systems and the way the cables run through the walls. There are mini media panels which are Bluetooth enabled for you to use audio ports wirelessly.



Safety with GFCI Receptacles, Cords, and Accessories

One of the most sought-after products provided by an electrical supplier is a ground fault circuit interrupter (GFCI) in the Philippines. These products protect you from the risk of fires and electrical shocks caused by ground fault currents that can escape from electrical equipment with damaged insulation. GFCIs can be used to replace the standard duplex outlets in your home, office, school, worksite, etc.

This essential product is also known as a ground fault interrupter or resident current device. It is designed to immediately shit off electric currents when an unnatural path is detected. Simply put, GFCIs turn of the power supply when it detects that the current is flowing through something hazardous like water.



Ways to Prevent Electrical Hazards

Ways to Prevent Electrical Hazards

Without a doubt, the most important benefit that an electrical supplier can provide is safety. The products mentioned above bring convenience to our everyday lives and prevent the potential dangers from electricity. But at the end of the way, you still have to be responsible and act with intentionality when it comes to ensuring that accidents do not occur with your electrical devices.


Check Extension Cord

You have to always make sure that insulation fully intact and free from cracks, tears, and damages, and that the power extension cables haven’t been knotted because they can cause conductor damage which leads to fire.


Check Insulated Tools for Damage Before Use

Once the insulation layer of a hand tool gets cut or cracked, the tool is no longer effectively insulated. This increases the risk of injury due to the fact that it becomes more of an electrical conductor.


Never Modify Electrical Plugs

You should never file down the blades, remove the ground pin, or do any modification to an electrical plug so that it will fit into a socket. This increases the potentialities of shock, electrocution, and fire.


Ensure That All Electrical Components Stay Dry

This is one of the most fundamental rules for basic electrical safety. NEVER MIX ELECTRICITY AND WATER. Store your tools and devices in areas that are dry and in a water-free environment.


Use the Right Extension Cord for The Job

Before you plug a power tool or device in, make sure that the wattage rating of the extension cord that you are about to use is greater than the power requirement of the equipment or device that it is powering. Using an extension cord to supply more wattage than its rated for causes conductor strain and overheating which increases the risk for fire.
