Understanding the difference between a 200A vs 100A electrical panel

Between a 100-amp and 200-amp electrical panel, the choice may seem difficult. If you have a 100-amp device, many electricians may recommend that you have it replaced with a more efficient one. Sound advice or unnecessary investment? Learn the key differences between these two types of panels.

More amperage for more devices

Today, a home relies much more on electrical power than it did a few decades ago. Appliances, lighting, heaters, air conditioning... almost everything in a home uses electricity.

Over time, you may need an electrical panel that can handle all these appliances. That's why a higher amperage panel is a must. By choosing a 200-amp panel, you'll be able to buy new appliances without worrying about the power supply.

More amperage for more safety

A panel that is too low in amperage can cause problems, especially in terms of safety. If you use too many appliances on a 100A panel, the panel may not be able to handle the current demand, leading to malfunctions in your electrical circuits. The box may even overheat, causing a possible fire.

That's why you should choose a panel with a certain margin in terms of amperage. You'll be able to enjoy your daily life without worrying that your latest appliance purchase will cause you problems.

Insurers are demanding on panel amperage

Today, many insurance companies pay particular attention to the amperage of your electrical panel. If your box has an amperage of 100A or less, they may be reluctant to insure your home. This is because the risk of accidents related to your electrical installation is higher.

Choose according to the size of the house

In the end, it is best to choose amperage based on the size of your home. A smaller property will require less electrical current, as there are fewer appliances that can be installed.

However, as soon as you expand your home, or if you are building a large home with large rooms, it is best to upgrade to a 200A or higher panel. This will save you from having to upgrade later.
