2018 Electrical Rule Changes

Ground-fault protection requirements for marinas

The Washington State Department of Labor & Industries has adopted rule changes to ground-fault protection requirements in marinas in response to a petition from the Northwest Marine Trade Association. The change will affect Washington Administrative Code 296-46B-555, "Special occupancies - Marinas, boatyards, and commercial and noncommercial docking facilities."

The new rule extends the 100 mA ground-fault level allowance for feeders, until Sept. 1, 2019, at which time the requirements published in the 2020 NEC would apply. The new rule will take effect July 1, 2018.

Here’s what happens next:

  • May 22, 2018: Adopted rules (CR-103) filed with the Code Reviser's Office.
  • July 1, 2018: Date rule would take effect.

Residential and Sign electrician specialties (Scope of Work)

The Washington State Department of Labor & Industries has adopted changes to the scopes of work for Residential (02) and Signs (04) specialty electricians. The new rule changes allow:

Residential (02) specialty electricians to work in taller buildings within multi-family dwellings of construction types III, IV, and V with non-metallic sheathed cable.

Signs (04) specialty electricians to retrofit existing exterior luminaires mounted on a pole or other structure with energy-efficient technology, such as LEDs. Previously, only those certified as journey level electricians (01), non-residential maintenance (07), or non-residential lighting maintenance and lighting retrofit specialty electricians (07A) could do that work.

The new rule took effect February 23, 2018.
