Your Home’s Circuit Panel: The Control Room

Think of the circuit panel as the control room of your home’s electrical system. This grey box is where the magic happens. It’s the hub that divides the electrical power flowing into your home into subsidiary circuits. If you experience frequent trips, it might be time to call an electrician for a panel upgrade.

Additionally, older electrical panels may not be able to handle the increased power demands of modern appliances and electronics. Upgrading to a new panel with more amperage can give you the peace of mind knowing that your electrical system can handle whatever you throw at it.

The “Internet of Everything” and Your Electrical System


Your home isn’t just a home anymore; it’s a connected ecosystem. The “Internet of Everything” refers to the interconnectivity of devices and systems that communicate with each other over the internet. Think Alexa, smart thermostats, and even smart refrigerators. While they offer convenience, they also add to your home’s electrical load. Ensure you have a robust electrical system that can handle this additional demand.

In addition to these specific items, any other device that is connected to the internet and can collect and share data with other devices can be considered part of the IoE. This includes things like laptops, smartphones, tablets, and even wearable devices like smartwatches and fitness trackers.

IoE data protection It is important to remember that each device or appliance that you connect to the internet, possesses another opportunity for exploitation. When we speak to the IoE, a strong network security protocol should be in place, along with a reliable program that detects these types of events.

The IoE is still in its early stages of development, but it has the potential to revolutionize the way we live and work. By connecting all of our devices to the internet, we can create a more efficient and interconnected world. For example, a smart thermostat can learn your heating and cooling preferences and adjust the temperature automatically to save energy. Smart lights can turn on and off automatically when you enter or leave a room, and smart locks can let you unlock your door remotely with your smartphone.

The IoE also has the potential to make our homes safer and more secure. For example, smart security systems can monitor your home for break-ins and send you alerts if something goes wrong. Smart smoke detectors and carbon monoxide alarms can notify you if there is a fire or gas leak, even if you’re not home.

Overall, the IoE has the potential to make our lives easier, more efficient, and more secure. As the technology continues to develop, we can expect to see even more innovative and useful IoT devices come to market.

It is important to understand that the IoE also opens up your home’s network to exploitation. Safety & security should always be a priority.

Smart home devices can be a fun, engaging and convenient. However, they do add to your electrical burden. Before making your home a smart home, have an electrical inspection done to ensure that you are not in need of a sub panel, or minor repairs so that you don’t put your current electrical system into overload.
