By Joshua Nicol, Licensed Washington State Electrician | Alki Electric
Serving King & Pierce County homeowners with over 30 years of industry experience and over 100+ surge protection installations
At ALKI Electric, we help homeowners across Seattle and the Greater Puget Sound area protect their homes from damaging power surges — whether caused by storms, grid fluctuations, or rare solar events.
As homes become more electrified with EV chargers, heat pumps, and smart devices, surge protection is no longer a luxury — it’s essential. Two of the most trusted solutions we install are the EMP Shield and the Eaton Ultra Whole-Home Surge Protector (CHSPT2ULTRA). Each plays a critical role in a modern home protection strategy.
Do you currently have these panels? Federal Pacific (FPE), Stab-lock or Zinsco
📌 What You Should Know About These Panels
❌ Federal Pacific (FPE)
Federal Pacific panels and breakers have a well-documented history of failure to trip when they should. They are not recommended for continued use in homes. Replacements are the safest option.
❌ Stab-Lok (Challenger / Federal Pacific variants)
Stab-Lok branded panels are notorious for defective breakers that may not trip under overload. Many insurance companies now require replacement before issuing a policy.
❌ Zinsco / Sylvania
Zinsco panels often have breakers that fuse to the bus bar under fault, meaning they do not protect the circuit as intended. Like the others on this list, they are no longer considered safe for modern electrical loads.
✅ Can ALKI Electric Replace or Upgrade These Panels?
Yes — absolutely.
We do not install new Federal Pacific, Stab-Lok, or Zinsco panels because they are obsolete and unsafe. Instead, we offer replacement with modern, code-compliant panels
If so, here’s how to choose the right surge protection for your Seattle-area home.
EMP Shield: Advanced Protection from Solar & EMP Events
The EMP Shield is designed to protect against extreme electrical events that standard surge protectors cannot handle.
EMP Shield Protects Against:
- Electromagnetic Pulses (EMP) from:
- Solar flares and coronal mass ejections (CMEs)
- Grid-level disturbances
- Solar flares and coronal mass ejections (CMEs)
- Lightning-induced surges
- Ultra-fast electrical spikes with response times measured in nanoseconds
Why Seattle Homeowners Should Consider EMP Shield:
The Pacific Northwest’s latitude and regional power grid make it more susceptible to geomagnetic solar activity than many parts of the U.S. While rare, these events can permanently damage sensitive electronics, solar inverters, and modern appliances.
For homeowners in Seattle, Bellevue, Kirkland, and Redmond focused on long-term electrical resilience, EMP Shield adds protection most homes simply don’t have.
🛡️ Includes a connected equipment protection guarantee (typically up to $25,000 against lightning damage).
Eaton Ultra: Everyday Surge Protection for Seattle Homes
The Eaton Ultra (CHSPT2ULTRA) is our most recommended solution for protecting against common, daily power surges.
Eaton Ultra Protects Against:
- Power surges from:
- Heat pumps and HVAC cycling
- EV chargers
- Washer/dryer and appliance startups
- Utility switching and outages
- Heat pumps and HVAC cycling
- Lightning surges entering through utility lines
- Excess voltage entering your electrical panel
Why ALKI Electric Recommends Eaton Ultra:
From West Seattle and Tacoma to Renton and Shoreline, Eaton Ultra provides affordable, reliable protection against the most common electrical damage risks — the 99% of surges homeowners experience.
⚡ Includes a connected equipment warranty (often up to $75,000 depending on installation and configuration).
Do You Need Both Surge Protectors?
For many Seattle homeowners, the best solution is a layered surge protection strategy.
✔ EMP Shield is ideal if:
You are concerned about rare but catastrophic events like solar storms or EMP-level surges.
✔ Eaton Ultra is ideal if:
You want reliable protection from everyday power surges caused by storms, appliances, and grid activity.
⭐ Best-in-Class Protection:
Installing both EMP Shield and Eaton Ultra provides comprehensive electrical protection — guarding your home against both routine surges and extreme electrical threats.
