Avoid Inspection Failures in Washington: Get Your Team Ready for the Electrical Code Amendments

Actionable Tip: Schedule a monthly “WAC/NEC Compliance Roundtable” with your electricians. In just 30 minutes, you can reduce rework by reviewing one Washington-specific code amendment and applying it to a real job from the past month.

If your electricians work in Washington State, they are now operating under two sets of electrical regulations: the 2023 National Electrical Code (NEC) and Washington’s amendments (WAC 296-46B). Many supervisors don’t realize how easily small deviations from state rules can lead to failed inspections and project delays — especially those on grounding, labeling, and equipment reconditioning.

This is where NTT’s 2023 National Electrical Code® With Washington State’s Electrical Code Amendments (based on Washington Administrative Code 296-46B) training becomes essential.

Why Supervisors Should Act Now

For supervisors, project managers, and safety leaders, the most urgent challenge is ensuring that your team understands not just the NEC, but the specific ways Washington’s amendments override or modify it. For example:

• GFCI requirements vary by state: Washington includes exemptions not found in the NEC.
• Breaker reconditioning after water exposure: NEC might allow it, but Washington mandates full replacement unless the OEM reconditions the gear.
• Disconnect labeling: Washington requires metal or engraved ID plates—more stringent than national code.

If your electricians aren’t implementing these state-specific requirements, project schedules and compliance are likely going to be negatively impacted.

Key Benefits for Employers

Here’s what successful organizations gain from this course:

✅ Pass inspections the first time – no guessing about what Washington inspectors expect.

✅ Reduce costly rework from misapplied NEC standards.

✅ Keep CEU hours on track – the course qualifies for 24 CEUs, including 4 WAC-specific hours.

✅ Bid on contracts with confidence, especially public-sector and L&I-audited projects.

Safety Tip: Replace, Don’t Recondition

One of the most overlooked changes in WAC 296-46B is the requirement that any breaker, fuse, or receptacle exposed to water must be replaced—not repaired. Many facilities wrongly assume these can be dried and reused, leading to equipment failures and citations. Supervisors should ensure these rules are reviewed any time flood damage or sprinkler discharge occurs.
