Wire Sizes 

Geo Drive electronics create a DC bus by rectifying the incoming AC electricity.  The current flow into 
the drive is not sinusoidal but rather a series of narrow, high-peak pulses.  Keep the incoming impedance 
small to not hinder these current pulses.  Conductor size, transformer size, and fuse size recommendations 
may seem larger than normally expected.  All ground conductors should be 8AWG minimum using wires 
constructed of many strands of small gauge wire.  This provides the lowest impedance to high-frequency 
noises.
