There is a call in American Samoa for better systems to find faults following a 14-hour power cut affected hundreds of people.
The Power Authority Chief Operations officer Fonoti Perelini Perelini says power has been restored to the eastern part of the main island, Tutuila.
He says it was the first extended power cut in a long time, which also caused water pumps to stop.
Mr Perelini says with cables underground, it was harder to find the cause of the problem quickly.
"We don't have the indicators on the side on the road where you can see the line can guide us that the line has failed from this to this. Now we don't have those in place yet cos we're still construct these underground systems and we need those fault indicators that will make it easier for the line crew to find the faults."
Mr Perelini says a single high voltage wire installed in the late eighties, was defective and caused the fuse to blow.
He says they're now investigating to see how the wire might have become defective and how to better handle such emergencies.
