Question 4

To prevent electrical shock, power tools should not be operated without the proper _____.

Accepted Answer

GFCI

Answer

A GFCI (Ground Fault Circuit Interrupter) is a safety device designed to protect against electrical shock. It works by detecting imbalances in the electrical current, which can indicate a ground fault, and quickly shuts off power to prevent serious injury or electrocution. Therefore, operating power tools without proper GFCI protection significantly increases the risk of electrical shock.

Question 5
