A 20-ampere branch circuit should not serve a single appliance with a rating greater than 16 amperes. An allowance of 125% of the appliance's rated current is made to ensure the circuit can handle start-up surges and ensure safety.

What does the power rating of an electrical appliance mean?
The power rating of an electrical appliance represents the rate at which the appliance uses electrical energy. It is typically measured in watts and indicates how much electricity the appliance consumes when it is in use. Higher power ratings suggest that the appliance uses more energy.
What will happen to an appliance if the fuse rating is less than the current an appliance needed?
If the fuse rating is less than the current an appliance needs, the fuse will likely blow or burn out. This is because the fuse is designed to protect the appliance from overheating or catching fire by interrupting the circuit when the current exceeds the fuse rating. It is important to always use a fuse with a rating that matches the current requirements of the appliance.
Where can you find the power rating of an electrical appliance?
You can find the power rating of an electrical appliance usually on a label or nameplate attached to the appliance. It might also be in the instruction manual that comes with the appliance. The power rating is typically measured in watts (W).
What is the fuse rating of 600watt appliance on a 220 volt supply?
To calculate the fuse rating for a 600 watt appliance on a 220 volt supply, you can use the formula: Fuse rating = (Power/Voltage). In this case, it would be 600 watts / 220 volts, which equals approximately 2.73 amps. Therefore, you would need a 3 amp fuse for the 600 watt appliance on a 220 volt supply.
What happens if power rating of an appliance is exceeded?
Exceeding the power rating of an appliance can lead to overheating, electrical fires, or damage to the appliance. It can also trip circuit breakers or blow fuses in your home's electrical system. It is important to only use appliances within their specified power ratings to ensure safe operation.
What does the power rating of an appliance mean?
what is the power rating of energy

What is meant by rating of electrical appliance?
possibly an efficiency rate on a scale that isn't presented on the appliance

Are fossil fuels efficient?
It depends on the efficiency rating of the burn appliance.
What does the power rating for an appliance tell us?
How much energy it uses
If you know the power rating of an appliance and the voltage of the line it is attached to you can you calculate the current used by the appliance?
Yes, you can calculate the current used by the appliance by dividing the power rating of the appliance by the voltage of the line it is attached to. The formula to calculate current is: Current (A) = Power (W) / Voltage (V). This will give you the amount of current flowing through the appliance when it is operating.
Is it true that a label on a new appliance shows its power rating?
Most new appliances have a power rating label on them. The Energy Star label is an indication that the appliance is more energy efficient than others and will tell you how much the appliance will cost you to run. Appliances that do not have an Energy Star label are not a good investment.
Can you run a three phase appliance on 240 volt power supply?
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
