Draw out circuit breaker positions, how many?

[Mjeelemco]

I had a question today on the practice exam. Seems like it would be an easy one?

A draw out type breaker has how many positions?
If anyone know the answer, could you provide an explination as well

Thanks for your help once again.

Per a Tech Quiz in NETA World Magazine 2007 Summer addition.
Question reads "List the positions a circuit breaker goes through when being racked out"
The answer given is 4:
1. Connected
2. Test
3. Disconnected
4. Withdrawn

Thanks for explaining this. The forth position "withdrawn" is the one that probably trips most people up when it gets the practice question that Mjeelemco listed.

Great find JohnRaz! I was able to locate Tech Quiz #80 from the Summer 2007 copy of NETA world that you referenced. A PDF copy is attached to this post if anyone is interested in some of the other questions.

3 Breaker Positions
-Connected
-Test
-Disconnected
*Withdrawn is not a 4th breaker position and the same as disconnected, do you guys agree?

Disagree. Withdrawn can imply that someone has removed the breaker from the cell entirely.

1. The Connected Position - the breaker in the operating position, both primary and secondary contacts made and the door may be closed.

2. The Test Position - the primary (power) contacts not made but the secondary (control) contacts are made. Any breaker test not involving power may be made in this position. The door may be closed in this position.

3. Disconnect Position - neither the primary nor the secondary contacts made. The door may be closed.

4. Fully Withdrawn Position - the breaker completely out of its compartment ready for removal from the inner housing. The door must be open in this position.

I agree, even in the article they reference says, "There are three main indications associated with draw-out breakers that every qualified person (https://testguy.net/content/225-NFPA-70E-Who-is-a-Qualified-Worker) must know:" reference (https://testguy.net/content/244-How-many-positions-does-a-circuit-breaker-have)

So need to update this so we don't get confused.

The devil is in the details when it comes to testing carefully reading the question when the items are so closely related can be tricky. Knowing that there are similar question and they are probably through out the test is great to know.

I would agree , withdrawn is not a manufactured position
