Another post on the same subject of our beach house.
House is 1940's era, has a ground/earth stake by the front door, approximately 2-3 meters from the main fuse box which is on an inside wall.
Soil type is sand. I am unsure how deep the stake goes, it looks original.
Main fuse box has the MEN link present.
What is the best way to determine if the earth stake is still OK, and hasn't rotted off etc. Is there a DIY way to do this, or do I need to call in a pro?
