Скачать или смотреть UFER Ground done right!

Installing a UFER Ground (aka Concrete Encapsulated Electrode).
NFPA 70®, National Electrical Code® (NEC®) "The Ufer ground must be at least 20 feet long and encased in at least 2 inches of concrete that's in direct contact with the earth. It can be made of either a bare copper conductor that's at least a #4 AWG or unencapsulated reinforcing steel rods that are at least ½ inch in diameter. The connection to the Ufer ground must be accessible, and a piece of rebar is usually located behind a blank cover installed on a mud ring at the clamp location."

Here are the resources I used to learn how to install this requirement for our project.
