The maximum load usage can be set up front

Power is managed when the unit automatically switches off appliances as soon as an excessive load is sensed, such as during peak demands. The unit limits the amperes (current) flowing through the electricity system. Selected appliances remain switched off for a period of time, typically 20 minutes. In about 20 minutes the intelligent unit assesses the power load again and then may switch the units back on or keep it switched off for longer. A great feature is that consumers can decide which unit has the lowest priority for them and that unit will be switched off first. The unit can be programmed to switch off appliances in order of priority from low to high.

Example of Programming the PowerGuard

Imagine a house having two geysers, under floor heating and an air conditioner. People always need access to hot water so a geyser can be kept as a high priority. Suppose the air conditioner is selected as the next highest priority, then under floor heating and finally, the remaining geyser.

Stoves, wall plugs and lights are normally not connected, so consumer will always have access to these appliances. However, if consumers want all these circuits to be connected to the PowerGuard, it can be done.
For this example we will assume that the maximum power load has been set to 45 AMPS

How will the program above be executed?

As soon as the intelligent PowerGuard senses a load exceeding 45 AMPS, it will switch off the geyser, because it was set as the lowest priority. The PowerGuard may switch off the under floor heating and the air conditioner if the load is still excessive. The appliances will remain off, as said before, for about 20 minutes. As soon as there is sufficient load capacity to avoid initiating a transgression appliances will be switched on according to the priority settings.
