NECA Reaffirms Standard for Installing Steel Conduits (Rigid, IMC, EMT)

Sep 10, 2013

NECA 101-2013, Standard for Installing Steel Conduits (Rigid, IMC, EMT) is now available from the National Electrical Contractors Association (NECA). This newly reaffirmed ANSI-approved standard describes installation procedures for steel rigid metal conduit (RMC), steel intermediate metal conduit (IMC), and steel electrical metallic tubing (EMT). Conduit with supplementary PVC coating is also included.

Minimum safety requirements for installing steel electrical conduit and tubing systems are provided in the National Electrical Code. As with any National Electrical Installation Standard (NEIS), NECA 101 goes beyond the Code by addressing the quality and performance aspects for installing these types of wiring methods. How bends should be made, how threads should be cut in the field, and how to effectively plan conduit and tubing runs for optimum routing, are just a few features covered in this important standard.

As with other NEIS, engineers and designers can rest assured that by referring to NECA 101 from plans and specifications they are establishing the confidence that owners are seeking relative to quality. NECA 101 continues to compliment electrical training programs by addressing many of “the how” to issues related to installing steel electrical piping systems. This revised standard is packed with solid, useful information the industry has come to expect from the NEIS.

“When electrical conduit is installed in a workmanlike manner, customers can see the difference” explains Michael Johnston, NECA’s Executive Director of Standards and Safety. This standard also provides information about correctly installing PVC-coated rigid conduit and effectively dealing with conduit corrosion issues. Essential information related to conduit EMI and grounding solutions is also included.

NEIS® are the only quality and performance standards for electrical construction. They are used primarily by electrical contractors, consulting engineers, facility managers, and other professionals who design and specify for electrical construction projects. With their installation detail, illustrations and thorough explanations, NEIS® are also a valuable training tool for electrical construction industry. The NEIS are regularly and meticulously revised and expanded to align with the current edition of the NEC and other applicable standards.

 “NECA’s National Electrical Installation Standards (NEIS®) library has grown over the years, and as new technologies emerge, the NEIS® evolve and keep pace,” Johnston said. Johnston also emphasizes that “the standards are constantly providing significant value to those in the electrical designing and engineering communities. The NEIS help professionals in developing design specifications in that they reduce and often eliminate specification writing time.” 

There are currently 44 NEIS®, with more essential standards in development, specifically standards related to renewable energy, energy storage and wind power generation systems. In addition, the NEIS® Yearbook Vol. 9 includes NECA’s newest NEIS, NECA 412 Standard for Installing and Maintaining Photovoltaic Systems, NECA 413 Standard for Installing and Maintaining Electric Vehicle Supply Equipment (EVSE), NECA 701 Standard for Energy Management, Demand Response, and Energy Solutions.



NECA 101-2013, Standard for Installing Steel Conduits (Rigid, IMC, EMT) is $20 for NECA members and $40 for non-members.
