Answer

Explanation:

Question 1: What happens if the human body comes in contact with an electrically energized conductor and the ground?

When the human body touches an electrically - energized conductor and the ground, an electric current will flow through the body. This can cause electric shock, which may range from a mild tingle to severe injury or even death depending on the amount of current, the path of the current through the body, and the duration of the contact.

Question 2: How many amps does a jigsaw use and what could be the reaction to the current if you came into contact with it?

Typical jigsaws use around 5 - 10 amps. If a person comes into contact with the current of a jigsaw, depending on the current magnitude, it can cause muscle contractions (which may prevent the person from letting go of the tool), burns, and in severe cases, cardiac arrest.

Question 3: What is grounding?

Grounding is the process of connecting an electrical system or equipment to the ground (earth) through a low - resistance path. This provides a safe route for electrical current in case of a fault, preventing electrical shock to people and damage to equipment.

Question 4: What does GFCI stand for? What does it mean?

GFCI stands for Ground - Fault Circuit - Interrupter. It is a safety device that monitors the flow of electric current in a circuit. If it detects an imbalance in the current (which can indicate a ground fault, such as a person coming into contact with a live wire), it quickly shuts off the power to prevent electric shock.

Question 5: Why should you not plug a GFCI - protected device into a GFCI - protected circuit?

Plugging a GFCI - protected device into a GFCI - protected circuit can cause unnecessary and potentially frequent tripping of the GFCIs. Each GFCI is designed to detect ground faults in its own circuit. When two GFCIs are in series, small differences in their sensitivity or operation times can lead to false trips.

Answer:

Question 1: Electric current flows through the body, causing electric shock with varying severity. Question 2: Around 5 - 10 amps; can cause muscle contractions, burns, and cardiac arrest. Question 3: Connecting an electrical system or equipment to the ground through a low - resistance path for safety. Question 4: Ground - Fault Circuit - Interrupter; a safety device that shuts off power in case of ground fault. Question 5: Can cause unnecessary and frequent tripping of the GFCIs due to differences in sensitivity or operation times.
