Electricity Inspection Section#2 The service box, ground and panel Quiz#5

You should have finished Study Session 4 before starting this study session. This study session deals with more of the conditions that we find related to panels. We will discuss conditions found with:

• fuses or breakers
• fuses only
• breakers only
• panel wires.

The estimated completion time is one hour.

Objectives
At the end of this study session, you should be able to:

• List all of the common conditions found in panels, including those related to fuses, breakers, and wires.
• Explain the causes and implications of these conditions.
• Describe the strategies used to identify these conditions.

• Question 4

  Needs Grading

  	What are the implications of oversized breakers?
  	Selected Answer: Overheating and potential fire hazard Correct Answer:   Oversized breakers allow wires to overheat without tripping. Response Feedback: [None Given]

• Question 5

• Question 6

  Needs Grading

  	What is a split receptacle?
  	Selected Answer: it contains two 120-volt circuits Correct Answer:   A split receptacle has the top part of the outlet on one circuit and the bottom part on a different circuit. Response Feedback: [None Given]

• Question 7

  Needs Grading

  	What is meant by linking in multiwire branch circuits?
  	Selected Answer: It means two breakers are out at the same time for the multi-wire connection Correct Answer:   Linking means that the fuses or breakers for multi-wire branch circuits have to be shut off in pairs. Response Feedback: [None Given]

• Question 8

  0 out of 0 points
