Interpreting wire type specifications on engineering drawings

Click For Summary

Discussion Overview

The discussion revolves around interpreting wire type specifications found in an electrical drawing, specifically the notation "3# 10+ 3# 12v- Teck symmetrical." Participants seek to clarify the meaning of the various components of this specification.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the clarity of the specification, noting that "10+" and "12v-" appear to reference voltage but is uncertain about the meaning of "3#."
  • Another participant suggests that "3# 10 awg+3# 12 awg" refers to the gauge of the Teck cables, but expresses uncertainty about what "v" and "symmetrical" might signify.
  • A request for additional information, such as a clearer image of the drawing, is made to facilitate better understanding.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the interpretation of the specification, and multiple competing views remain regarding the meanings of the components.

Contextual Notes

Limitations include the lack of detailed context about the drawing and the specific definitions of terms used in the specification.

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]:

However, I don't know what "v" signifies -may be "vertical"-and "symmetrical", also.
