Electrical Service Upgrades: A Move from 100A to 200A in Residential Homes

In the age of modern technology, where homes are increasingly laden with electronic gadgets, appliances, and efficient heating systems, the electrical demands have surged dramatically. The backbone supporting this tech-driven lifestyle is the electrical service capacity of our homes. Many older houses were built with a 100A service, which may now be insufficient for contemporary needs. This brings forth the necessity for an upgrade – a leap from 100A to 200A. In this article, we’ll delve into the reasons, benefits, and considerations for such an upgrade.

Why Upgrade from 100A to 200A?

Many homeowners wonder about the need to upgrade their electrical service. The reasons are manifold:

  • EV Chargers: With the rise in electric vehicles, many homeowners are installing EV chargers. These chargers often require increased power, making the move from 100A to 200A a practical choice for seamless vehicle charging.
  • Modern Appliances Demand More: Today’s appliances, be it Air Conditioning, HVAC systems, ovens, or home entertainment systems, demand more power. To prevent frequent tripping and ensure smooth operation, an upgrade is essential.
  • Safety Concerns: Older homes with 100A service can often become overloaded. This not only increases the risk of blackouts but can also pose serious safety hazards like electrical fires.
  • Home Value Boost: An upgraded electrical system can increase the resale value of your home. Potential buyers often prefer homes that are ready to accommodate modern electrical demands without further investments.

Benefits of Upgrading to 200A Service

Upgrading your home’s electrical service brings along a plethora of benefits:

  • Consistent Power Supply: Say goodbye to unanticipated power disruptions. With a 200A service, there’s a consistent flow, ensuring all your appliances work without a hitch.
  • Space for Future Additions: Planning on a hot tub or perhaps a home theater? With a 200A service, your home is prepared for future electrical demands.
  • Enhanced Safety: With reduced overload chances, the risks of electrical mishaps diminish substantially. This ensures a safer environment for your loved ones.

Key Considerations Before Upgrading

Embarking on an electrical upgrade requires some thought:

  • Assess Your Needs: Before jumping in, analyze your current and anticipated future electrical demands. This will guide your decision-making process.
  • Hire Professionals: Such upgrades demand expertise. Always rely on licensed electricians to ensure quality work and safety.
  • Cost Implications: While there’s an upfront cost associated with the upgrade, it’s an investment. Weigh the long-term benefits against the initial expenditure.

Things to Remember

  • Your home’s geographical location might dictate certain specific requirements.
  • The process might require a temporary power shutdown. Be prepared.
  • Always secure necessary permits before starting the work.

In a world that’s constantly evolving, staying updated is not just a luxury but a necessity. Upgrading your home’s electrical service from 100A to 200A is a forward-looking decision that guarantees safety, efficiency, and peace of mind.

The team at TDR has been amazing to work with - I can’t say enough good things about them. When you hire any trade to help you there’s a lot of trust put in them to do what they are asked to do but my experience with them is they go above and beyond and they think outside the box to make the job the best it could possibly be, make it workable for the business and they really take pride in their work. Liam and his team have been professional, helpful, and accommodating, and brought ideas for my business I hadn’t even thought about to improve it and I’m so grateful for that!

We have used TDR's services for home improvements (light installation) and they were prompt and professional. More recently, TDR has been working with our strata to identify options for Electric Vehicle charging in our complex. They provided our council with an EV Ready Plan which was approved and reimbursed by BC Hydro, and Taylor has helped us immensely in understanding not only the technical aspects of an EV charging system installation but also the requirements under the ever-changing rebate system.

It was a pleasure to work with TDR from the friendliness of the office personnel to the consultant who came out to do up a work order and cost, to the electrician who came and did the work. I highly recommend this company. Very easy to work with and I couldn't be happier with the quality of work from new plug outlets, to lighting installations, and wiring the ceiling for a fan and installation.
