hello, I have recently moved into a sectional title flat that is newly built. At the moment there are no appliances plugged in. the only things connected are a stove, geyser and heat pump and lights.

whenever i switch on the lights for about 5 minutes and then switch them off after a few seconds the meter in the meter box outside trips. although no breaker trips or falls either in the DB box or the meter box outside. I then have push the breaker switch outside in the meter box down wait for a click sound, push it up again and connect the meter again for the power to come back. this has also happened once when i was only usng a drill at different plug points. i would use the drill then leave it on the floor after use then the meter would trip again.

please note nothing in the house is drawing power at the moment there is no appliances plugged in (example fridge, freezer etc)

so my thinking is that when there is a load being used inside the house and then i switch off that load, there is left over power in the cables that travels back through the load line and trips the meter.

I have tested everything even totally disconnected the geyser, stove and heatpump at the DB box and it still trips.

what could be causing this extra energy to be going back through the load line?

do you think that if i had something always pulling a load such as fridge on that the extra energy will flow to the fridge and not back to the meter box.



please help
