Commercial and Residential Electrical Panel changes

Battling the Elements – Electrical Panel Work in Rainier, OR & Longview, WA

1.

Understanding Codes & Regulations

• Oregon (Rainier area): As of October 1, 2023, electrical installations are governed by the 2023 Oregon Electrical Specialty Code (OESC), based on the 2023 NEC with state-specific amendments.

• Washington (Longview area): Work must comply with the 2023 NEC as adopted by the state and local jurisdictions (like Longview’s electrical code), along with the Washington Cities Electrical Code for commercial and residential installations.

• Both require permits, inspections, and that panelboards be listed or evaluated by an approved lab.

Challenges of Working in Rain

• Safety Hazards: Working on electrical systems in the rain raises the risk of electrocution, short circuits, and dangerous equipment exposure.

• Best Practices from the Field: One experienced voice noted:

  
  

  “I wouldn’t recommend opening any electrical panels if it was raining or snowing without proper resources. Although, you could put a giant tarp over the area before working…”

  
  

  This highlights the importance of mitigating moisture through protective shelters and gear — not just exposure avoidance.

3.

Safety Compliance in Wet Conditions

• Oregon OSHA: Emphasizes careful inspection of wiring, cabinets, and flexible cords, particularly in damp, wet, or exposed environments.

• Oregon State Rules:

  
  

  • Ensure clear workspace, maintaining at least 36 inches in front of panels and 76 inches vertically.

  • In damp or wet locations, only fixtures rated and approved for such environments may be installed, ensuring water cannot enter wireways or panel components.

Practical & Effective Mitigation Tips

• Tarp & Shelter Solutions: Deploy durable, water-resistant tarps or temporary canopies around the work area to keep panels and tools dry.

• Rated Materials: Use weatherproof enclosures, GFCIs, and equipment rated for wet conditions (e.g., with suitable IP/NEMA ratings).

• PPE Matters: Insulated rubber gloves, boots, and eye/face protection help maintain a safe barrier from water and electricity.

• Inspection Strategy: Check for moisture intrusion immediately before and after work—ensure dry conditions before activating circuits.

• Workspace Clearance: Respect minimum working clearances and ensure panels are accessible and unobstructed, even amid rain-protection setups.

Local Climate Considerations

Rainier, OR, and Longview, WA, are typified by the Pacific Northwest’s frequent rain and damp weather. Even if not actively raining, high humidity can still introduce risks:

• Trickle moisture on surfaces can begin corrosion or cause unexpected leakage currents.

• Mold or rust can compromise metal enclosures or grounding connections.

Final Thoughts

Weather-proofing electrical panel work isn’t just a matter of preference—it’s mandatory for safety and code compliance. Whether you’re servicing a home in Rainier, an office in Longview, or any mixed-use space between, the rain demands respect. Proper planning—through protective covers, rated equipment, thoughtful PPE, and strict clearance—ensures that your electrical upgrades or replacements not only pass inspection but also keep everyone safe.
