Why does the main fuse trip when guests are there?
The main fuse trips when guests inadvertently switch on too many appliances simultaneously, which is not a fault but a safety device. A metering module with four groups shows consumption per group, so you know which combination is causing the problem and can adjust per group without shutting down the entire property. If the fuse trips structurally even without peaks, the connection is probably undersized and upgrading via the grid operator, or investigation by an electrician in case of outdated wiring, is the right step.
