Standards for electrical work—2020 National Electrical Code (NEC), 504.1, amend ch 504
PUBLIC SAFETY DEPARTMENT
Notice of Intended Action
Proposing rule making related to standards for electrical work
and providing an opportunity for public comment
The Electrical Examining Board hereby proposes to amend Chapter 504, "Standards for Electrical Work," Iowa Administrative Code.
Legal Authority for Rule Making
This rule making is proposed 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 proposed 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.
This rule making has no fiscal impact to the State of Iowa.
After analysis and review of this rule making, no impact on jobs has been found.
Any person who believes that the application of the discretionary provisions of this rule making would result in hardship or injustice to that person may petition the Department for a waiver of the discretionary provisions, if any. Pursuant to the provisions of rule 661—10.222(17A), the Department does not have authority to waive requirements established by statute.
Any interested person may submit written comments concerning this proposed rule making. Written comments in response to this rule making must be received by the Department no later than 4:30 p.m. on September 15, 2020. Comments should be directed to:
Department of Public Safety
Oran Pape State Office Building
215 East 7th Street
Des Moines, Iowa 50319
A public hearing at which persons may present their views orally or in writing will be held as follows:
September 17, 2020
First Floor Public Conference Room 125
Oran Pape State Office Building
Des Moines, Iowa
Persons who wish to make oral comments at the public hearing may be asked to state their names for the record and to confine their remarks to the subject of this proposed rule making.
Any persons who intend to attend the public hearing and have special requirements, such as those related to hearing or mobility impairments, should contact the Department and advise of specific needs.
Review by Administrative Rules Review Committee
The Administrative Rules Review Committee, a bipartisan legislative committee which oversees rule making by executive branch agencies, may, on its own motion or on written request by any individual or group, review this rule making at its regular monthly meeting or at a special meeting. The Committee's meetings are open to the public, and interested persons may be heard as provided in Iowa Code section 17A.8(6).
