What is mechanical interlock?Explain the uses?
Answer Posted / prashant
Mechanical interlock is a means by which to ensure that any
person even unknowingly cant put him or the installation to
risk.
Eg: you might have seen some panels which cant be opened
unless the breaker is turned off. This is one case
The other most imp use is in places where generators are
used . Mechanical interlock ensures that at a time only one
of the supplies ( either generator or normal ) are working
else the generator may start feeding the line which is a
very dangerous situation.
