Switching between sources safely.
WHAT A TRANSFER SWITCH DOES
Connects your premises to one supply or another, never both.
WHY NEVER BOTH
Back-feeding generator power into the grid is dangerous to line workers and illegal.
WHAT MANUAL SWITCHING INVOLVES
Someone physically changing over.
WHAT THAT COSTS
Delay, and dependence on a person being present.
WHAT AN AUTOMATIC SWITCH DOES
Detects loss of supply, starts the generator, transfers load, and reverses on restoration.
WHAT IT PROVIDES
Unattended operation Consistent behaviour Shorter interruptions
WHAT IT REQUIRES
A generator capable of remote starting Correct installation Maintenance
WHAT TO CONFIGURE
The delay before starting The warm-up period before transferring The cool-down before stopping
WHY COOL-DOWN MATTERS
Stopping a hot engine immediately shortens its life.
WHAT TO TEST
The whole sequence, periodically.
HOW
Simulate a supply failure and observe.
WHY TEST
Transfer switches fail silently, and the failure appears during an outage.
WHAT TO CHECK IN TESTING
That it starts That it transfers That it returns to grid That it stops after cooling
WHAT TO NEVER DO
Wire a generator into the premises without a proper switch.
WHY
It is a genuine danger to people.
WHAT TO USE
A qualified electrician, for any installation.
