GCFI
Protects from electrical shock by detecting imbalance of current in normal conductor pathways by opening the circuit. When two conductors differ more than 5mA, GCFI opens in as little as 1/40 second
Trench

Angle of Repose
greatest angle above horizontal plane at which a material will lay without sliding
Granular Soil
consists of gravel, sand, or silt with little or no clay
Cohesive Soil
clay or soil with high clay content. Doesn’t crumble easily
Highly Cohesive Soil
gravel or rock particles held together with cohesive particles. Can’t be crushed into powder or particles by finger pressure
