State Requirements

Nebraska electrical licensing is administered by the Nebraska State Electrical Board. The state's residential electrician classification is referred to in licensing law as the residential journeyman electrician classification.

A residential journeyman electrician is qualified to install electrical wiring, apparatus, and equipment for residential installations and supervise apprentice electricians within the authorized scope of the license.

Nebraska defines residential installations to include single-family and two-family dwellings and qualifying multifamily residential buildings not larger than three stories in height.

Important considerations include:

  • Examination Approval: Applicants must receive approval from the Nebraska State Electrical Division before PSI scheduling.
  • Electrical Experience: Applicants must satisfy the qualifying experience and training requirements for residential journeyman licensure.
  • Examination Score: A minimum of 75% is required to pass the examination.
  • Electrical Code: Nebraska adopted the 2023 National Electrical Code with state amendments effective August 1, 2024.
  • Professional Scope: Residential electricians must work within the responsibilities authorized by their license.
  • Electrical Safety: Regulated installations must comply with applicable electrical codes and safety requirements.
  • Contractor Licensing: Electrical contractor licensing involves separate professional and business requirements.

The Nebraska State Electrical Act and State Electrical Board Rules establish the legal framework governing electrical licensing and professional responsibilities.
