How much power does your home need?
Calculating how much power your home needs involves looking at the amperage load all of your appliances and fixtures consume, and making sure that load never exceeds 80 percent of the electrical capacity. If the load is regularly above 80 percent of the capacity, it's time to consider upgrading your electrical panel.
How many watts can a 20 amp circuit support?
For example, a 20-amp, 120-volt branch circuit has a total capacity of 2,400 watts (20 amps x 120 volts), and with the 80 percent rule in mind, can support light fixtures and plug-in appliances adding up to 1,920 watts of power without the risk of circuit overload.
How many amps can a home have?
Homes built between the 1950s and 1960s tend to have a capacity of 60 amps. Homes built from 1960-1980 (or upgraded older homes) will likely have a capacity of 100 amps. Homes from 1980 onwards have a minimum capacity of 200 amps.
What is the difference between electrical capacity and electrical load?
Electrical capacity is the amount of electricity your home can support, while electrical load is the amount actually being used. Calculating how much power your home needs involves looking at the amperage load all of your appliances and fixtures consume, and making sure that load never exceeds 80 percent of the electrical capacity.
How many watts can a 100 volt system support?
The same formula can be used to determine the capacity of the house's overall electrical service. Because a home's main service is 240 volts, the math looks like this: In other words, a home with a 100-amp system can support up to 19,200 watts of power load at any given time.
Can I use a 15 amp GFCI circuit outside?
You could probably use the 15 ampere basement circuit to power outdoor lighting, and water feature (just make sure it's all GFCI protected). If you're going to be using power tools outside (power washer, electric mower, trimmer, hedge clipper, etc. Then you're going to want to run a new 20 ampere GFCI protected circuit.
