Working on an enclosure in which there will be low voltage high precision circuitry (my area of more experience) coexisting with fairly high current (~15A) 120VAC load wiring (my area of less experience). Would be it be advisable to twist those AC wiring pairs which carry equal + opposite currents to reduce the amount of field radiated from these wires? Or is it considered sufficient just to route them together side-by-side?
Obviously I don't care about the susceptibility of the mains wiring, only its emission and the susceptibility of the low voltage circuits. Never seen this done before but don't work with mains powered devices much. Don't want to reinvent the wheel or do something dumb / non-standard so anyone's experienced take would be appreciated.
