By keeping the ground system for grounding and the neutral system to carry load current for 120V loads.
This is why the ground and neutral are to be kept totally separate after the initial bond at the service entrance .
Running neutral current on the ground system raises the ground system voltage above true earth potential .
It is difficult enough to keep the ground system at ground potential. Frozen soil, dry soil, dandy soil . Not unusual to be able to apply 120V direct to ground rods and not trip a 15 amp breaker . It does however drive the dew worms up out of the ground .
A service ground connected to a drilled well casing or to ground plates buried 10+ feet deep maybe required.
All barn loads should be 240V where possible . !20 V loads should be balanced so the neutral current back to the transformer is minimal.
As previously stated, PVC conduit or tech cable is the preferred method .
Anyone who things that the ground and the neutral is the same . Do tell us why a line, neutral AND and ground are routed together to wall receptacles etc.

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
