Default Shunt wiring running next to main feed cables?

Gents,

I plan on running my shunt sense wires bundled with my main feed wire that goes to my breaker panel (which is also bundled with my positive battery cable to the master solenoid).

Is this a bad idea? Is the shunt sense wiring sensitive to high current nearby?

It is a Dynon EMS system.

Paul

Have mine running in the same bundle as the alternator and the starter wires. No problemo.

...from the shunt - usually 1 amp = 1 mV

Any magnetically induced voltages created by high currents affecting the two small shunt lines should be in the same direction, so the difference between the two shunt lines will remain the same.

First order quick analysis, but it says there should be negligible effect...

Default Signal & power wires

As a rule, it is asking for signal disturbance trouble to place any wire that is carrying a signal along side a wire carrying current in the Amps range.
