A single large building may be provided with two or more separate services if permitted by which of the following?

• A. An architect
• B. Special permission
• C. Written authorization
• D. A master electrician

Answer: (B)

Special permission from the authority having jurisdiction is what allows two or more separate electrical services for a single large building. The electrical system needs rigorous review to ensure safety, proper coordination of service disconnects, metering, backfeed protection, and grounding. The architect designs the building, but they don’t grant or approve how the electrical supply is arranged. A master electrician handles the installation and overall compliance, not the authorization to provide multiple services. Written authorization alone isn’t the formal process used to authorize this arrangement in most jurisdictions; the formal approval must come as special permission from the AHJ after the plans are reviewed.
