Estimate the consumption of your electrical appliances

In this video, we will learn to estimate the consumption for domestic appliances.In this video, we will learn to estimate the consumption for domestic appliances.

Estimating this consumption makes it possible to estimate the cost of the energy that will be used.Estimating this consumption makes it possible to estimate the cost of the energy that will be used.

Verifying the electrical wattage of an appliance makes it possible to determine if it is compatible with the home’s electrical installation, or in other words if, when the appliance is connected, it will not trip the circuit breaker.Verifying the electrical wattage of an appliance makes it possible to determine if it is compatible with the home’s electrical installation, or in other words if, when the appliance is connected, it will not trip the circuit breaker.

To do this you will need a calculator, an electric bill, a domestic appliance and its data plate.To do this you will need a calculator, an electric bill, a domestic appliance and its data plate.

This procedure will be done in 3 steps that we will explain in this video.This procedure will be done in 3 steps that we will explain in this video.

STEP 1: HOW TO TELL THE DIFFERENCE BETWEEN THE NOMINAL VOLTAGE AND WATTAGE OF AN APPLIANCESTEP 1: HOW TO TELL THE DIFFERENCE BETWEEN THE NOMINAL VOLTAGE AND WATTAGE OF AN APPLIANCE

The nominal voltage is the normal voltage for use of an appliance.The nominal voltage is the normal voltage for use of an appliance.

In France, for example, the voltage is 220 V, and so the appliance must be made to be compatible with this value: 220 V.In France, for example, the voltage is 220 V, and so the appliance must be made to be compatible with this value: 220 V.

It must correspond to the efficiency level of the voltage of the terminals of the electrical socket where the appliance is plugged in.It must correspond to the efficiency level of the voltage of the terminals of the electrical socket where the appliance is plugged in.

This information can be found on the appliance’s data plate.This information can be found on the appliance’s data plate.

It is expressed in volts.It is expressed in volts.

The nominal wattage is the normal wattage for use of the appliance.The nominal wattage is the normal wattage for use of the appliance.

This is the energy that corresponds to the appliance’s consumption.This is the energy that corresponds to the appliance’s consumption.

This corresponds to the electrical energy exchanged during the use of the appliance.This corresponds to the electrical energy exchanged during the use of the appliance.

This information can be found on the appliance’s data plate.This information can be found on the appliance’s data plate.

It is expressed in watts.It is expressed in watts.

STEP 2: HOW TO CALCULATE THE APPLIANCE’S CONSUMPTIONSTEP 2: HOW TO CALCULATE THE APPLIANCE’S CONSUMPTION

Use the appliance’s wattage multiplied by the time it functions (in hours) per day or per year, to obtain the consumption in Watt/hours by day or by year.Use the appliance’s wattage multiplied by the time it functions (in hours) per day or per year, to obtain the consumption in Watt/hours by day or by year.

This is the consumption that will be billed by the country’s electrical network management authority, often expressed in kilowatt-hours (kWh).This is the consumption that will be billed by the country’s electrical network management authority, often expressed in kilowatt-hours (kWh).

For example: for this coffeemaker with a wattage of 500 Watts, used 1 hour per day.The energy exchanged will be 500 Wh/day.For example: for this coffeemaker with a wattage of 500 Watts, used 1 hour per day.

Multiply by 365 to obtain the result for the year: 500 x 365 = 182 500 Wh or 182.5 kWh"The energy exchanged will be 500 Wh/day.

To find out the cost of consumption for this appliance, multiply by the price of the kilowatt-hour.Multiply by 365 to obtain the result for the year: 500 x 365 = 182 500 Wh or 182.5 kWh"

If the kWh costs 0.11 € after tax, the invoice will be in the amount of 182.5 x 0.11 = 20 euros per year.To find out the cost of consumption for this appliance, multiply by the price of the kilowatt-hour.

STEP 3: TAKE THE NECESSARY PRECAUTIONS PRIOR TO CONNECTING A DOMESTIC ELECTRICAL APPLIANCEIf the kWh costs 0.11 € after tax, the invoice will be in the amount of 182.5 x 0.11 = 20 euros per year.

Before connecting any electrical appliance, verify that the wattage for the installation is adequate.STEP 3: TAKE THE NECESSARY PRECAUTIONS PRIOR TO CONNECTING A DOMESTIC ELECTRICAL APPLIANCE

For example, 3, 6, 9, or 12 kVA , depending on the subscription.Before connecting any electrical appliance, verify that the wattage for the installation is adequate.

It is expressed in kilovolt amperes (kVA) equivalent to the kWh on your electricity bill.For example, 3, 6, 9, or 12 kVA , depending on the subscription.

Then estimate the value of the wattage of the other electrical appliances that are already installed.It is expressed in kilovolt amperes (kVA) equivalent to the kWh on your electricity bill.

For example, to connect a 2000 W electrical stove top to an installation that already has a 500 W coffeemakerThen estimate the value of the wattage of the other electrical appliances that are already installed.

you need 2500 W.For example, to connect a 2000 W electrical stove top to an installation that already has a 500 W coffeemaker

The installation’s wattage must thus be greater than 2500 Volt amperes or 2.5 kilovolt Amperes.you need 2500 W.

If your installation is 6 kilovolt Amperes, the circuit breaker will not be triggeredThe installation’s wattage must thus be greater than 2500 Volt amperes or 2.5 kilovolt Amperes.

You now know how to estimate the consumption of an appliance and take the necessary precautions prior to connecting it.If your installation is 6 kilovolt Amperes, the circuit breaker will not be triggered

You now know how to estimate the consumption of an appliance and take the necessary precautions prior to connecting it.
