Nowadays there is lot of load shedding in our area.
Yesterday around 11 PM, there was a power cut.
Watchman of our immediate next building, switched ON the generator of his building.
After 2 hours, power returned.
But generator was also ON till morning..,..!!!!
I was worried because main supply and generator both are supplying electricity to the building ...!!!
What if there is an overload to electrical appliances ???
That would result in either short circuit or back feeding to power grid itself !!!
In such scenario,
The outcome is determined entirely by how the generator is connected to house.
In a correctly installed system, two power sources are isolated and should never " crash " with each other !!!!
With correctly installed system, it ensures that house is connected to only one system at a time.....
