Which two statements are correct for a safe wiring installation to the terminal block of the switch or endpoint? (Choose two.)

B. Verify that DC power is live and within 24 VDC voltage range before starting wiring.

C. Verify that the DC power circuit includes an overcurrent protective device that limits the DC current to 5 A.

D. Because this is a low-voltage DC circuit, anyone can install this wiring without electrical training or qualifications.

E. Connect the positive 24 VDC conductor to the V terminal and connect the negative 24 VDC return wire to the RT terminal.

F. A ground wire can optionally be connected to the screw terminal on the front of the switch.
