What does this symbol mean this Wiring Diagram?

Question

For the wiring diagram on the LEFT SIDE what does the lines above "C" and "NC" mean? Does it mean a standard wire hooks these two areas together? Or some grounding terminology? But doesnt the "C" also connect to the "Live wire" (notice the "L" line below "C").

Answer 1

The drawing shows (top section above terminals) the internal connections NC is (without being energized) connecting to C (common) . When the internal control changes state the connection moves and connects NO to C.
Below the terminals is the connections for you to wire to.
If your field device is the same voltage and source then yes the L is to have a jumper wire to C and the white wires are also together on the N terminal

Answer 2

This is a Schematic representation of a Single Pole Double Throw switch.

Answer 3

The "C" stands for Common, or basicaly power in.
The "NC" stands for Normaly Closed. as if the switch was sitting on the table with no one touching it, power would travel thru that portion of the switch
The "NO" stands for Normaly Open. Which means power would not travel thru that portion of the switch if it were just sitting there.

Answer 4

Looks like a jump to NC.

Answer 5

its a switch that goes to either NO or NC which stands for normally open or normally closed... usually used for latches
