What Happens When the Wiring is Upgraded in a Home

If you have been working from home since the beginning of the pandemic, you may have discovered certain issues in your home’s electrical system. Creating a home office is not only about having a workstation, a desktop, an ergonomic chair, or a stable internet connection. Electrical wiring also plays a vital role in ensuring that your home is hospitable and conducive for working. Some houses might need to upgrade their wiring to make the transition possible.

This article will look closer into how electrical wiring differs in a new and old home. It will also go over the steps you need to take to upgrade your system.

The Difference Between Residential Wirings in New and Old Homes

The steps you need to take differs depending on how old your current residence and wiring are. For example, if you live in a relatively new home, you might not experience any problems. In general, modern homes have enough amperage (strength of electric current).

On the other hand, older houses require a wiring upgrade to accommodate a work-from-home setup. These updates could include:

● Installing electrical outlets.

● Replacing old cable wires.

● Replacing receptacles or adding new lighting.

Some homeowners can conduct these changes on their own. However, it is still vital that the job is done right to avoid accidents or fire.

New Homes

To understand it more, here is a breakdown of what the electrical system is like for new houses:

● These houses are specifically designed with a 200-ampere capacity, which is the basic capacity required by the electrical code. This setting is usually enough for a household that is not maintaining a business that requires a strong electric current.

● These houses have multiple standard outlets that can accommodate different appliances and equipment.

How to Upgrade Your Electrical System

Usually, the reason for upgrading an electrical system at home is the need for more outlets. While using an extension cord could suffice, the safest route would be to permanently add and install new outlets in your home.

● For adding one or two outlets: The electrician would pull out power from an existing outlet and add new electrical boxes and outlets right next to it. The process would involve drilling holes and pulling wire to the new boxes.

● For adding wall outlets with USB ports: The process would be similar to installing a new standard outlet.

● For adding lights: Typically, you simply add a floor or desk lamp and plug it into your wall outlets. Another option is adding ceiling boxes with wires, which will require wire installation.

Some homeowners can do simple electrical upgrades on their own, but it is always best to ask a professional electrician to do the job for you. That way, you can assure that the wiring and other equipment are correctly installed. The case will be different if you live in an older home.

Old Homes

These are homes that have been present for many decades. These houses use old wiring, old knobs, and tube systems. Often, they face ground wiring problems. So, if you live in an old house, you better not DIY your electrical upgrade.

Before the modification of electrical systems takes place, here are some steps that your electrician should do:

● Check if your current wiring is properly grounded.

● Check if the main panel can accommodate an update or would need to be replaced.

● Assess if the wire, outlet, switch, and breakers would need to be replaced.


Now that everything relies on technology, updating your electrical wiring is advantageous. Just make sure that you call a professional electrician or conduct the necessary wiring checkup before performing the update. Safety should still be the priority for you and the entire household.
