Avoiding Your Next Inspection Failure: Common Commercial Electrical Violations in Washington

Why Commercial Electrical Inspections Fail

Inspectors in Washington—whether through L&I or city jurisdictions such as Seattle, Bellevue, Everett, Redmond, and others—focus heavily on safety, documentation, installation quality, and equipment suitability. Most failures stem from oversights during construction or from outdated infrastructure inside existing buildings.

Common Electrical Violations Seen Across Washington

Improper grounding and bonding

Grounding continues to be one of the most frequently flagged issues. Incorrect conductor sizing, missing bonding jumpers, or improper terminations create safety risks and lead to instant failures.

Incorrect breaker sizing or inadequate labeling

Breakers must match conductor size, load calculations, and equipment requirements. Panels that lack clear, permanent labeling also fail quickly because inspectors want to see accurate circuit identification.

Unsupported or improperly secured conduit

Loose, sagging, or improperly spaced EMT or MC is a routine violation—especially during tenant improvements when multiple trades share tight ceilings and walls.

Outdated or unlisted equipment

Panels or switchgear that no longer meet listing requirements—or equipment from manufacturers no longer supported—often get flagged for replacement. Older buildings are especially vulnerable as loads increase.

Poor termination practices

Over-torqued or under-torqued lugs, doubled neutrals, exposed copper, or overheated conductors are red flags. These issues show up frequently when timelines are compressed or inexperienced installers are involved.

Coordination errors between trades

Mechanical, plumbing, and low-voltage installations often impact electrical clearances. Obstructed panel working space is a common cause of failed inspections in TI environments.

Washington-Specific Triggers That Catch Property Managers Off Guard

Many owners assume national code rules apply universally. In reality, Washington and its municipalities adopt unique interpretations and amendments. Examples include:

• City-specific permitting and inspection sequencing

• Different approaches to AFCI/GFCI requirements

• Local amendments for equipment clearances

• Documentation and load calculation requirements

• Approved vs. prohibited wiring methods in certain occupancies

  
  

Ignoring these differences can lead to avoidable rework.

How to Prepare for a Smooth Electrical Inspection

A clean inspection starts with planning. Before scheduling an inspector, ensure the following:

• All panels are permanently labeled

• Conduit and cable support spacing meets code

• Equipment is listed, current, and free from damage

• Working clearances around electrical gear are unobstructed

• Breaker and conductor sizing has been verified

• Permits and panel schedules are ready for review

• Cover plates, junction box lids, and support hardware are installed

  
  

A quick pre-inspection walk with a qualified electrician eliminates most issues before an inspector arrives.
