For installations in buildings other than one- and two-family dwellings, what is the minimum required distance for a receptacle outlet from the indoor installed electrical service equipment?

  1. 15 feet

  2. 20 feet

  3. 25 feet

  4. 30 feet

The correct answer is: 25 feet

The minimum required distance for a receptacle outlet from indoor installed electrical service equipment is specified as 25 feet for installations in buildings other than one- and two-family dwellings. This requirement is put in place to ensure safety and accessibility, reducing the risk of accidental contact with the service equipment and preventing damage to both the receptacle outlet and the electrical service itself. This distance serves multiple purposes, including allowing sufficient space for maintenance and servicing of the electrical equipment and minimizing the potential for interference or noise from the service equipment affecting the operation of the receptacle outlet. Compliance with this standard helps to ensure a safer working environment and aligns with electrical codes that govern installation practices.
