Standards for electrical work—2020 National Electrical Code (NEC), ch 504
PUBLIC SAFETY DEPARTMENT
Adopted and Filed
Rule making related to standards for electrical work
The Electrical Examining Board hereby amends Chapter 504, "Standards for Electrical Work," Iowa Administrative Code.
Legal Authority for Rule Making
This rule making is adopted under the authority provided in Iowa Code section 103.6.
State or Federal Law Implemented
This rule making implements, in whole or in part, Iowa Code section 103.6.
Purpose and Summary
The purpose of this amendment is to update the Standards for Electrical Work to the National Electrical Code, 2020 edition. Consistent with rule making in this chapter, the entire National Electrical Code (NEC) is adopted, with the amendments included in this chapter. It is the intention of the Department and the Board to not make further amendments, regardless of new additions to the NEC, until it is necessary for the state of Iowa. A significant effect of the adoption of the 2020 edition of the NEC would have been the requirement for 250-volt receptacles, but the Board, in addition to adopting the 2020 edition of the NEC by reference, is amending the 2020 edition to remove that requirement. Although the ground fault circuit interrupter requirement for 250-volt receptacles is removed, it is possible that future NEC amendments will return this provision to the administrative rules.
Public Comment and Changes to Rule Making
Notice of Intended Action for this rule making was published in the Iowa Administrative Bulletin on August 26, 2020, as ARC 5152C. A public hearing was held on September 17, 2020, at 10 a.m.in First Floor Public Conference Room 125, Oran Pape State Office Building, 215 East 7th Street, Des Moines, Iowa.
Don Iverson, with Schneider-Square D, suggested the Board accept the 2020 NEC without amendments. Mr.Iverson stated that documentation submitted to Code Panel 2 reflected the number of lives lost around outside air conditioners and indoor appliances due to electrocution. As a safety advocate for ground-fault circuit interrupter (GFCI) protection, he would like the Board to change direction in amending the 2020 NEC, stating that GFCI technology has been around since the late 1960s and electrocutions have decreased significantly due to GFCIs installed in homes. Mr.Iverson would like the Board to reconsider its stance on removing 250-volt language, and suggested a possible middle ground to GFCI protection in consideration of public safety. Possible middle ground would be to restore Article 210.8A, where the subcommittee struck the 250-volt language, and then place a sunset on outdoor outlets in Article 210.8F to become effective at the next code adoption.
Tim McClintock, with the National Electrical Manufacturers Association (NEMA), thanked the Board for wanting to adopt the 2020 NEC. Mr.McClintock had previously submitted written comments and reiterated his request that the Board adopt the 2020 NEC without amendments. Mr.McClintock explained the process that the National Fire Protection Association (NFPA) uses with the development of the NEC, where the process is open, transparent and balanced, and accredited by the American National Standards Institute (ANSI). Changes are not made to the NEC unless substantiated by logical reasoning, research, data and statistics — all to promote the practical safeguarding of persons and property from hazards arising from the use of electricity. Mr.McClintock also touched on GFCI equipment that was in the 1971 NEC edition, and stated that published data from the U.S. Consumer Product Safety Commission shows decreasing trends in electrocutions in the United States. Mr.McClintock stated that NEMA urges the Board to move forward with adoption of the 2020 NEC and reconsider the proposed amendments to remove GFCIs.
Chris Higgins, an Iowa-licensed master electrician and electrical contractor, stated that his only concern is if the 2020 NEC is adopted without amendments, there may be no indication if the electrocutions were due to faulty installation or faulty equipment. Mr.Higgins understands that one life is too many, but questioned whether that is justification for increased cost of GFCIs being put on consumers.
Trevor Williams submitted the following written comments:
1.Proposed amendment to 210.8(A)(5). Add the following amendment to existing Exception to (5):
