NECA Updates Standard for Temporary Electric Power at Construction Sites

NECA 200-2010 Standard for Installing and Maintaining Temporary Electric Power at Construction Sites is now available from the National Electrical Contractors Association (NECA). NECA 200 is the latest revised publication in the National Electrical Installation Standards (NEIS)® series published by NECA.

“Temporary construction lighting and power must be safe for workers and is definitely not an ‘anything goes’ situation on construction sites,” said Michael Johnston, executive director of standards and safety at the contractors’ association. “NECA originally developed NECA 200 to clarify many essential requirements for installing temporary power and lighting for construction projects, including use of ground-fault circuit interrupter protection for personnel.”

NECA 200 describes installation criteria for temporary electrical power and lighting systems at construction sites, operating at 600 volts or less. It covers the planning, installation, expansion, maintenance, cutover, and removal of the temporary power system. “Adopting this standard on a jobsite is intended to ensure a safe, adequate, functional, and reliable temporary electrical power system for all trades working on site,” Johnston said.
