15 amps how much watts

More powerful electrical units can draw as much as amps. For these units, you already need amp breakers. They are hooked up to V because V would need even more current. Hello Ernest, you can find our watts to voltage converter here. Overloading a 15 amp breaker can lead to very dangerous situations. It is best to have a certified, trusted electrician to assist with any electrical work. If you have a 15 amp breaker, or a 20 amp breaker, there is not a specific number of lights and outlets that can go on it.

It is dependent on the wattage of the lights. This is because the number of outlets on a 15 amp or 20 amp circuit depends entirely on what you plug into those outlets and how much wattage and amperage it uses. The more water flowing through the hosepipe, the stronger the current is.

Volts are the measurement used to determine how much force is needed to cause the electric current to flow. In keeping with the earlier example, you could think of volts as the water pressure in the hosepipe, which makes the water flow.

Amps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. The higher the wattage is, the more power and output from the appliance. But if you put a single watt lightbulb in the bathroom light fixture, you create a situation where a tripped circuit breaker is likely. Electricians usually calculate circuit load with a 20 percent safety margin, making sure that the maximum appliance and fixture load on the circuit is no more than 80 percent of the available amperage and wattage provided by the circuit.

In our sample bathroom, a amp circuit providing 2, watts of power can quite easily handle 1, watts of demand, with 25 percent safety margin. This is the reason why most electrical codes call for a amp branch circuit to serve a bathroom. Kitchens are another location where volt branch circuits serving outlets are virtually always amp circuits.

In modern homes, it is normally only general lighting circuits that are still wired as amp circuits. Exactly the same principle is used to calculate the demand on a circuit serving a single appliance, such as a microwave oven, garbage disposal, or air conditioner. A large microwave oven with a built-in vent fan and light fixture can easily demand 1, to 1, watts of power, and an electrician wiring a dedicated circuit for this appliance would likely install a amp circuit that provides 2, watts of available power.

On the other hand, a large 1 hp garbage disposer drawing 7 amps watts , can easily be served by a dedicated amp circuit with 1, watts of available power. The same method of calculation can be used for any dedicated appliance circuit serving a single appliance.

But because the circuit requires a 20 percent safety margin, the circuit needs to provide at least An electrician would install a amp volt circuit to serve such a water heater. Most electricians will slightly oversize the dedicated circuit size to allow for future changes.

For example, if you have a fairly small watt microwave oven, the electrician will normally install a amp circuit even though a amp circuit can easily handle this appliance.
