Why is clearance important and what are the standard clearances for a pad-mounted transformer near a driveway?

Clearance ensures safety for utility workers and protects equipment. The standard guidelines include 10 feet of clearance in front, 4 feet on the sides and back, and 10 feet of vertical clearance for overhead protection.

Is Your Electrical Transformer too close to your driveway?

A pad-mounted electrical transformer can be placed near a driveway, but it requires specific clearance zones for safety and utility access. The required distance varies depending on local utility regulations, but a standard configuration is 10 feet of clearance in front and 4 feet on the sides and back.

These are general safety guidelines for a green pad-mounted transformer box, but always confirm the exact requirements with your local utility provider before planning any construction or landscaping.

10 feet of clearance in front: This is the side with the lock and access doors that utility workers need to open and work in. This space is critical for using long tools (“hot sticks”) to safely work on energized equipment.
4 feet of clearance on the sides and back: This space allows for air circulation, which prevents the transformer from overheating.
10 feet of vertical clearance: A minimum overhead clearance is also necessary for safety.
