What is the role of the solenoid in an RCD?

• To increase the voltage.

• To trip the device when necessary.

• To balance the current flow.

• To provide additional power.

What should be pressed at regular intervals to keep mechanical parts working effectively in RCDs and RCBOs?

• Reset button

• Test button

• Power button
