Interpreting wire type specifications on engineering drawings

Click For Summary
SUMMARY

The discussion centers on interpreting wire type specifications in electrical drawings, specifically the notation "3# 10+ 3# 12v- Teck symmetrical." Participants clarify that "3# 10" and "3# 12" likely refer to three strands of 10 AWG and 12 AWG Teck cables, respectively. The terms "v" and "symmetrical" remain ambiguous, with suggestions that "v" could denote "vertical." A link to Southwire's product catalog is provided for further reference on Teck cables.

PREREQUISITES
  • Understanding of electrical wiring specifications
  • Familiarity with American Wire Gauge (AWG) standards

I have an electrical drawing which specifies a wired connection as 3# 10+ 3# 12v- Teck symmetrical.
What do all these numbers mean?
 
Engineering news on Phys.org
not really enough info the 10+ and 12v- look like voltage references ... 3#, no idea

how about a sharp and clear pic of what you are talking aboutDave
 
In my opinion, it could be:
3*10 awg+3*12 awg Teck cables
See [for Teck cable, for instance]:
http://www.southwire.com/ProductCatalog/XTEInterfaceServlet?contentKey=prodcatsheetT91
However, I don't know what "v" signifies -may be "vertical"-and "symmetrical", also.
