Chart Or Publication; Human Factors; Procedure
We were being vectored on a box pattern to wait for an arrival to CHO ahead of us. ATC assigned 3000 ft. and heading 120. We approached a ridgeline and the EGPWS (Enhanced Ground Proximity Warning System) issued 'Terrain! Terrain! Pull up! Pull up!' I disconnected the autopilot and climbed to 4000 ft. We advised ATC of the EGPWS warning and asked for a new clearance. ATC said the minimum vectoring altitude in the area was 3000 ft. ATC vectored us back around and we flew the approach. ATC vectored us too close to a ridgeline. I climbed to 4000 ft. Adjust the sensitivity of the EGPWS as we were at the MVA (Minimum Vector Altitude).
EMB-145 Captain reported encountering an Enhanced Ground Proximity Warning System alert during initial approach to airport.
