What's Wrong Here?

Hint: This smaller conduit body (LB fitting) was installed so a supply could run to a piece of electrical equipment near a cabana in a hotel.

The following individuals correctly identified the Code violations shown in the December column: Cari Korstad, Code inspector, Electrical Inspections, City of St. Louis Park, Minn.; Jim Budke, director, electrical engineering department, Toltz, King, Duvall, Anderson & Assoc., St. Paul, Minn.; Danny Cribbs, electrician, facilities management, University Medical Center, Tucson, Ariz.

Each winner noted the following violations. The installation violates Art. 314. Conductors and equipment are acceptable only if approved by an authority having jurisdiction (90.7 and 110.2). Using a smaller conduit body to tap into a larger conduit body violates 110.3(B) because listed or labeled equipment must be installed and used in accordance with any instructions included in its listing or labeling requirements. It's clear that this product is being used for a purpose other than its intended use.
