Are Challenger Electrical Panels Safe?

Guidance for Homeowners in Enfield, CT

At Mission Electric, LLC in Enfield, CT, we frequently inspect older homes throughout Hartford County, including Windsor, Somers, and East Windsor. One brand we encounter is Challenger, commonly installed in Connecticut properties built or renovated in the 1980s and early 1990s. While these panels served many homes reliably, questions about long-term performance arise today.

Background on Challenger Panels

Challenger panels were affordable and widely used during that period. Eaton acquired the brand in the 1990s and discontinued it. Original equipment is now obsolete, though compatible replacements exist.

Official Safety Record

The U.S. Consumer Product Safety Commission (CPSC) documented one voluntary replacement program in 1988 for specific Challenger GFCI breakers (types HAGF-15 and HAGF-20, manufactured February to April 1988). The issue affected only the ground-fault protection feature—a mechanical part could detach—while standard overcurrent protection remained functional. No injuries or shocks were reported.

For full details, see the official CPSC recall page: https://www.cpsc.gov/Recalls/1988/challenger-electrical-equipment-corp-offers-replacement-program-for-9000-gfci-circuit

No broader panel or breaker recalls appear in CPSC records.

Common Concerns Raised by Electricians

Some licensed electricians note potential poor contact between certain breakers and bus bars in aged installations, which can lead to overheating under normal loads. This isn’t universal but may prompt recommendations for evaluation, especially in homes with higher modern demands like EV charging.

Connecticut adheres to the National Electrical Code (NEC), and existing panels aren’t mandated for replacement unless issues arise during inspections or upgrades.

Why Connecticut Homeowners Consider Upgrades

Upgrading an older panel provides:

• Enhanced reliability for today’s loads

• Full compliance with current Connecticut codes and NEC

• Support for additions like Tesla Wall Connectors or Powerwalls (as your local Tesla Certified Installer)

• Potential benefits with homeowners insurance—policies vary, so check yours

Identifying a Challenger Panel

Look for “Challenger” on the panel door, breakers, or interior label. Homes wired or updated in the 1980s–1990s often have them.
