There is a very dangerous myth floating around, one which could actually result in severe injury and even death – “Electricity always follows the path of least resistance”. This is one of those myths that results from a general fact being blown way out of proportion.

Forget colleges and engineering schools, most high school students learn that electricity does behave this way, as a part of the basics of electricity and resistances. Worryingly, this myth isn’t just stated as a fact, it’s a commonly followed practice in many electrical circuit designs, especially when it comes to grounding.

Walk into any industrial plant that uses motors or pumps and you’ll find they’re all connected to ground rods. Ask anyone why that’s done and you’ll likely get the same response everywhere (even from the people in charge of the electrical maintenance) – It’s to eliminate the potential differences.

If you’ve lived in the Washington, DC area for a while, you know how severe summer rains and winter storms can be. Too often, the result is a power outage that forces you to shut your home office down, puts your refrigerated goods at risk, and can even present a health hazard if someone in your household relies on oxygen to help them breathe. Fortunately, a home generator can bridge that gap between when the power goes out and when your service is restored.

Home generators offer a number of advantages to Maryland, Virginia, and DC homeowners, the largest of which include:

There are instances where NEC and other regulators recommend dedicated circuits for certain loads. Typical loads to put on individual branch circuits include sensitive electronic equipment such as computers. In addition, water heating systems, large appliances, and other high capacity loads that zap power require a dedicated circuit.

Run cables all the way to the main service panel and avoid connecting to other existing circuits. The same conductor size should be used throughout the branch circuit.

Electric water heaters, HVAC equipment, hot tubs and other appliances should each have a nearby disconnect that is easily visible and accessible. The power disconnect can be provided by the main or sub panel breaker, a dedicated switch, or a power cord that can be unplugged.

The branch circuits should have adequate current carrying capacity, adequate and grounding.

Typical branch currents include:
