Good morning Tim,
Hope you had a great week end.
My understanding as one of the IPC 610 trainers is
For round post under 3-49 page 40
Yes
Acceptable Class 1 and 2 
B. Minimum wrap for less than 180° of contact between the wires and the terminal.
Page 41 3-52 is for terminal
Please note page 40 is for round posts
When reading 610 it is very importance to note special words.

Also revision C is out.
Your issue is on page  5-37 and is now a Process Indicator for Class 2 and is referred to as Terminals - wrap- Turrets and Straight Pins.
revision C is some what easier to understand.
Good luck .
If you need more please feel free to e-mail me directly or call.

    Hi everyone, I am confused! I am preparing to teach a 610 class (rev. B) and I came across a problem dealing with wire wraps.
       Just below figure 3-49 on page 40, item B states that "minimum wrap for round posts has less than 180 degrees of contact between the wires and the terminal". This is listed as acceptable for class 1 and  2. However, under figure 3-52 on page 41 it 
states minimum wrap contacts the terminal 180 degrees, or 90 degrees (if mechanically secured). 
       My question is; is it acceptable for class 2 to have a wrap less than 180 degrees on a round post or not? Thanks in advance for your help!
