This weeks change allows us to use the steel frame of a building in place of running a conductor all around a building.   Bonding each item that needs to be bonded into part of the Grounding Electrode system.  Such as the case of the electrical service on one side of the building and the cold water service on the other.

2014 Code Change 250.68(C)(3) Grounding Electrode Connection

In the 2014 NEC they are going to allow us to extend the connection from Grounding Electrode (concrete encased electrode)

into a wall or above grade. In the past we could only have the conductor from the rebar extending out from the concrete

encasement, now we can have the rebar extend out from the encasement for a connection.  So this will work when the

town or city will not let you make this connection in the meter can, and you have a main breakers panel as your first means

of disconnect, you bond the neutral to this electrode in the wall near the panel if needed.  As you can see in the picture on the

right the connection has to be accessible.

 

Till next time be safe work safe.

This weeks change comes from Chapter 2, article 200.4(B) identifying neutral conductors.  This change is for all enclosures not just in a panelboard.  So when you run several circuits with neutral through a Junction box remember to identify them, so we know which circuit the serve.
