Is it true that a tree over 50 ft. high can be used as overhead service support for a single-story residence?

True
False
Only if it's a certain type of tree
Only under special conditions

The correct answer is: False

Using a tree as overhead service support for any structure, including a single-story residence, is generally not permissible under standard electrical codes and regulations. Trees can sway in the wind, have variable strength and stability, and their nature can change over time, posing a significant risk to electrical service lines if they are used as supports. In addition, using a tree for this purpose would typically violate National Electrical Code (NEC) requirements, which specify that overhead services must be supported by structures designed to carry such loads, like poles or buildings, rather than natural objects like trees. Therefore, regardless of the height of the tree or its type, it is not considered a safe or compliant practice to use it as a support for overhead electrical services. This highlights the necessity of adhering strictly to safety codes and standards in electrical installations.
