Main information
What it could mean
An overload happens when the total demand on a circuit or the installation exceeds what it's sized to handle on a sustained basis.
Safety first
Cut down on high-consumption appliances used at once (oven, air conditioning, heating) while the cause is checked.
Next step
If overloads happen often, it may require redistributing circuits or increasing available power, assessed based on actual consumption.
Frequently asked questions
Which appliances most often cause overloads?
The highest-consumption ones, like ovens, hobs, electric heating or air conditioning used together.
Is upgrading contracted power always the fix?
Not always; sometimes redistributing appliances across existing circuits is enough.
How do I know if my installation is undersized for current usage?
Frequent tripping when using everyday appliances together is a clear sign.
