While you may see an Amp rating on many devices throughout your home or business, you may not appreciate what this actually signifies.
All electric appliances display an ampere rating. This is often shortened to just amps or even an “A.”
In simple terms, amps are a measure of the electrical current the machine uses when it is run at full power.
For example, a four slot toaster may have a rating of 10A. This type of machine is usually single phase and fitted with a standard three pin plug. For safety reasons, the plug will be fitted with a fuse that protects against any electrical surges.
Although it may appear just a larger version of this appliance, a commercial eight slot toaster could be rated at 20A. This has double the output and requires more power than is provided using a standard plug. So, while this type of toaster may still be single phase, it will need to be hardwired to the power supply.
In commercial settings, a highly powerful combination oven may have a rating of 3x49A. This is a three phase piece of equipment with each “phase” needing 49 amps. This adds up to a total load of 147 amps. This would obviously be one of the most demanding appliances in the kitchen.
Therefore, in this situation, the maximum load of the electric circuit in the kitchen would need to be calculated to ensure that it is not being overloaded.
Fortunately, for this or any other electrical installation, all our recommended electricians can perform any calculations and ensure that any new appliances can be accommodated by the electrical circuit in the room.
