Proper ground fault protection will prevent __ drilling into electrical wiring the drill bit from slipping in the chuck electric shock the need for a trigger lock

## Step 1<br />Ground fault protection is a safety measure that is designed to prevent electric shock. It does this by interrupting the circuit when an imbalance between the incoming and outgoing current occurs. This imbalance could indicate that current is flowing to the ground, which could mean that a person is in contact with an energized part of the equipment.<br /><br />## Step 2<br />The other options provided, such as drilling into electrical wiring, the drill bit slipping in the chuck, and the need for a trigger lock, are not directly related to ground fault protection. These issues are more related to the physical operation of the drill and the safety measures taken during its use, rather than the electrical safety measures provided by ground fault protection.
