Grounding

• Grounding is the process where the foundation of the building or buildings are instituted with the electrical system. Electrical wiring is created within the foundation, usually with the conductor underneath the ground. The conductor roots through the ground to the utility company. The conductor may be connected to one building or multiple buildings through what are called feeders.
  
  

The National Electric Code

• The National Electric Code, or the NEC, governs over how to ground a building or multiple buildings effectively. If a new building needs to be routed to a utility company, the NEC dictates that the electric current, through the ground, must run through a low resistance path.
  
  

Low Resistance Path

• A low resistance path is one of the main specifications for all groundings. Essentially, engineers do not want the wiring to network through the earth in a haphazard way. The circuits could impact other buildings or could be ineffective in supplying energy if the earth dirt harms the wiring.
  
  

Other Options

• The National Electric Code dictates that if there is no clear way to ground a new electrical system between multiple buildings, then the electrical wiring must be networked in an another way. According to the NEC, grounding should never be the first option for installing a path to electric utilities.
  
  

Feeders

• The best way, according to the NEC, for new or multiple buildings to be connected is through feeders. Once a building or existing multiple buildings have an established grounding, it is recommended that an outside electrical line, called a feeder, connects a new building to one or more multiple buildings. This way, the new building does not have to connect to the existing grounding or create a new grounding line. The new building merely connects itself to the other buildings through a feeder.
