What is the minimum distance from a building that a padmount transformer 75kva or less can be located?

The minimum distance a padmount transformer of 75kVA or less can be located from a building is three feet. This requirement is primarily established to ensure safety, accessibility, and adequate clearance for maintenance and emergency services.

Three feet provides enough space to allow for the safe operation and maintenance of the transformer while minimizing risks associated with electrical hazards, such as potential electrical arcs or fires. It also ensures that enough room is available for any associated infrastructure, such as conduits or cables that may need to run between the transformer and the building.

Additionally, this distance helps to comply with local codes and regulations, which are designed to protect personnel as well as structures nearby. The specifics of the code can vary by locality, but a three-foot clearance is a commonly accepted standard in many regions. This distance is critical for ensuring that both the transformer and the building it is near can operate safely without interference or risk to personnel.
