Line vs Load – 5 Differences Explained

Line and load are 2 words that resonate in the electrical world. Before you work on connecting electrical devices together, understanding the concept of line Vs load is important.

What are the differences between these two? Read on to learn about the fundamental differences between line and load.

What Are Line and Load?

A line vs load is a wire which supplies electricity to your devices, such as a panel or switch. On the other hand, a load is a wire that easily takes electrical currents away from a machine.

Firstly, you must know what both sides mean. There are multiple kinds of line and load with unique properties. With respect to electrical wiring, line wires hold and transfer more power than load wires.

That is the main reason why line side wire is usually larger vs load side wire.

Line Vs Load Wire

Line and load wires are 2 separate entities and should not mix. If you are dealing with electrical connections, know these signs to avoid polarity reversal. Here are some parameters that can help you differentiate between the two:

Wire Positioning

Typically, the line wire connects to an electrical switch and comes from the bottom area. In contrast, load wires enter from above. Moreover, these line vs load points of connectivity has individual markings that help in indicating the type of wires for a point.


Color codes help in easy identification of various types of wires in an electrical circuit. However, there is not one standard code; they vary according to country.

Wire Size

Because electrical devices usually decrease voltage or current, line wire carries more power vs load wire. Therefore, line side wires are generally larger in size than load side wires. This characteristic is extensively visible if the power difference is enormous.

Measuring power features

Electrical power downstream from a unit is lower than upstream. Therefore, measuring the voltage or even current at the ends can easily differentiate between line and load wires. Also, volt sticks or pens and digital multimeters give a non-invasive measurement of these parameters.

Line And Load – Other Mode of Identification and Mix Up

Other than these methods, you should know that every device has indicators of its line and load side to so that the connections are proper.

However, if you reverse them, some may suffer from any consequences. An example of such a condition is a single-pole, single-throw switch. It works with perfection even after there is a reversal in connection.

But, in multiple switches, the connections are directional. Therefore, it will not work correctly if reversed.

Final Words

In a nutshell, polarity reversal creates a potential shock hazard, short circuit risk, or fire outbreak. So, it is better that you leave this in the hands of professionals. Appoint On Point Contracting for your electrical issues.

9 Easy Ways To Deal With A Clogged Shower Drain

There are multiple reasons why your shower drain gets clogged really badly. The top 3 causes of a clog in the drain include:

  • Use of soap that contains talc, fats, and wax. They form hard residues inside with water minerals and are most definitely the primary cause of a clogged drain.
  • Dirt is something that takes up a decisive turn gradually after months of buildup.
  • Hair is amongst the worst culprits that cause this problem. The strands lost from the head make a ball after intertwining with the dirt, turning them into a ball.

9 Ways To Unclog a Clogged Shower Drain

If you find the water standing after a shower session, the reason is a clogged drain that needs proper cleaning. Here are 9 ways you can fix a clogged shower drain.

A Drain Snake

A drain snake is more like a metal coil with a spiral end that is a cheap, simple, and convenient solution to take out dirt and hairballs.

Remove the grille and draw the cable down the drain. Next, turn it anticlockwise to push the coil forward. Stop once you feel resistance. Now, turn the crank clockwise to screw up the clog.

Unclog by your hand

If you have seen something going in and blocking the drain, wait out a few minutes to let the water go off slowly. Then, grab a pair of rubber gloves (for protection of your hands). Remove the top metal lid and grab whatever hinders the water flow to unclog the drain under your shower.

Hot Boiling Water

This method is efficient for unclogging the drains that are full of grease and soap residue. However, it is not a good choice if the pipes of your household are of PVC material.

Baking Soda and Vinegar Solution

You do not have to mix the two. Just pour half a cup of baking soda and immediately follow it with a glass of vinegar.

Biological Drain Cleaner

Biological cleaners are mostly enzymes that effectively work to reduce the drain clog. It is an eco-friendly method that requires no dirty work.

Coat Hanger

This option is viable when you can’t get your hands on a drain snake. Just prop the hanger down the drain with the hooked area digging into the clog.


Wet or dry vacuums may be able to suck in all the material which contributes to pose inherence to water flow. Keep the hose over the drain grille and switch on the device.

Cup Plunger

This is one of the oldest methods of cleaning the shower drain. Use the cup-shaped mouth to suck the clog up.

Caustic Soda

Caustic soda is one of the hazardous yet most effective methods to deal with drain clogs. If none of the methods work for you, this one might. Prepare a mix using 3 cups caustic soda in around 3 liters of water and pour the solution down the drain.


You may think that DIY drain unclogging is the best option to go for. However, that is not the case. In reality, some of the features will cause you more trouble and money than calling professionals.

10 Components of The HVAC Duct System

A duct system is necessary if one wants to set up an air conditioning system, especially in office spaces or other commercial buildings. An HVAC duct system is pretty complex and consists of many components that need to be installed under professional guidance for the whole network to run without disruption.

The first part of the entire process is selecting the pipeline. The duct material for the entire system is galvanized steel and aluminum. Former, galvanized steel is fairly a common choice to make ductwork of any shape or size. Aluminum is suitable when a pipe is lightweight needed; it is also easy and quick to install.


They are central collection and distribution components for the HVAC duct system. From multiple large size vents, the air moves towards a central air handler. It is then directed to a single large space or maybe to individual rooms/areas that need hot or cool air.


Takeoff is one of the components when it comes to a duct system; they are fittings that allow the correct portion to flow in the main duct that is to be diverted into every branch.
The shapes, either rectangular, oval, or round are easily accommodated. Moreover, the air is pumped mostly via a diffuser, grille, or register outlets.

Canvas Connector

This part helps minimize the loud noise and vibrations that the air handler generates. It is a rubbery, canvas-looking material inserted inside the duct before and after the air handler.


The coil is one of the parts in a duct system that either heats up or cools down the condition indoors via the air that flows; this is possible by drawing out heat and moisture.


Stack boots or heads are branches – vertical ducts which let the air flow out vertically within very thin walls. Other times, the stack is also known as a furnace in or wall stack.

Turning Vanes

Turning vane is one of the parts that fit inside ductwork where direction changes (e.g., at 90° angle turns. This helps minimize turbulence air flow resistance on the whole.


They easily connect two pipes of the entire duct system together.


A duct fitting can have two main functions: control of the air volume and smoke or fire detection. Air volume control dampers may or may not be automatic. At the same time, smoke & fire detectors seal all the ducts and shut them off the system.

Spiral Pipe

A spiral pipe is more like an extension of the round duct system. The spiral is a result of the coil made of metal fixed inside a rigid tube. There is a smooth interior that allows low friction loss and a grooved seam on the outside.


Zoning in the duct system is meant to divide a home or an office space into multiple regions that help in better control of the temperature and efficiency of the heating or cooling system.


A well-designed HVAC system is crucial for proper installation and efficient working. Why don’t you dial (832) 966-7000 and talk to one of the experts from On Point Contracting? We can surely come up with adequate solutions for your troubles.

How To Wire A 2 and 3 Prong Plug With Ease

DIYs these days are in full swing because of two advantages. Firstly, it helps people manage everyday household troubles themselves; secondly, it saves heaps of money. One of the most common trouble is electrical routes and consequent appliance damage. This blog will discuss how to wire a plug with ease and safety.

However, no matter how safe it may seem, we recommend involving an electrical contractor for this service since electricity is hazardous, which may result in fatality. If you are searching for a competent and reliable contractor for your project, why don’t you give On Point Contracting a call for help?

How to Safely Wire a Plug

Wiring plug connections is pretty easy; however, connecting the hot and neutral wires with the proper prongs is crucial. Miswired plugs pose a severe shock risk that may lead to a fire.

There are two types of plugs to work with:

  1. 2 prongs
  2. 3 prongs

How to Wire a 2 Prong Plug

You will need the following items:

  • A 2 prong plug
  • Wire strippers
  • A screwdriver
  • Utility knife

Step 1

Always disconnect the plug from the outlet before starting to wire it.

Step 2

Cut the old plug from the power cord with a utility knife. If you do not have one, wire strippers can do the job too. You can strip the wire easily with the help of a needle nose plier, grab and twist the cord and lay it between the wire stripper to split it.

Step 3

Time to wire the 2 prong plug. The cord side, which has ridges, goes with the broader prong, whereas the smooth area towards the narrow one. A silver screw is used for the former, while gold is best for the latter prong.

Step 4

Once done, close the cover, tighten its screw, and you’re done!

Wiring a 3 Prong Plug

The items needed and the first two steps for wiring a 3-prong electrical plug are the same as that of a 2-prong plug.

Step 1

Remove the wire or your plug from the power outlet.

Step 2

Cut the old plug from the power cord with a utility knife.

Step 3

Remove insulation from the power cord in this step. Carefully cut, do not go too deep to avoid a short circuit.

Step 4

Strip the wires apart to insert them in the plug, which has a strip gauge to guide how much insulation should be removed.

Step 5

The insulation is removed easily with the help of wire strippers; twist and pull.

Step 6

It is time for wiring. The plug has 3 kinds of screws; silver, green, and gold. While the power cord has white, green, and black wire. The white wire goes with silver, green and green together, whereas black wire connects with a gold screw.

Step 7

Secure them together, and voila! You have your plug ready.


Wiring a plug is pretty easy, and you can do it without assistance at home. We hope that this information will help you in the future. Still, we urge you to connect with a professional from On Point Contracting for your needs. Playing with electricity is no joke, as the results can be fatal.
