-With AC circuits a two-or-three conduc- 

 tor path twisted pair is the best available 

 configuration to cancel the alternating 

 magnetic field from each conductor. 

 Magnetic and electrostatic shielding may 

 also be required. Physical separation of 

 conductors to reduce alternating fields 

 would be almost impossible. 



— Inductive loads on DC power require spe- 

 cial switch and circuit breaker considera- 

 tions. Separation of conductors could 

 possibly make a normally resistive load 

 inductive. If the conductors were sepa- 

 rated by several feet, a single turn loop 

 of considerable area and significant in- 

 ductance could be formed, but the loop
