Main information
What it could mean
If the main switchboard isn't receiving power, the source could be the incoming supply, the main power control breaker, or a cut from the supplier.
Safety first
Check first whether the cut also affects neighbours or the rest of the building before assuming it's an internal fault.
Next step
If the cut is exclusive to your home and not the supplier, the switchboard and incoming connection need checking to locate the exact fault.
Frequently asked questions
How do I know if it's a supplier cut or my own installation?
Check whether it also affects neighbours or other homes in the building; if only yours is affected, it's usually internal.
Could it be a fault in the main power control breaker?
Yes, that's one of the usual points to check when the switchboard isn't receiving power.
What should I do while it's resolved?
Avoid handling the switchboard and get the exact source of the cut checked.
