Earth electrode with inspection pit

Many earthing designs place the top of each rod in an inspection pit so the connection can be examined and the electrode disconnected for testing. Layout drawings show the electrode inside a small square or circle representing the pit, often with an electrode number.

A distinction that matters

An electrode with an inspection pit is accessible; a plain earth electrode symbol may be buried with no access.
