Circuit Breaker Inspection, Testing & Retrofits
Keep protective devices ready to trip when it matters with inspection, testing, maintenance and retrofit solutions.
Breakers That Work When You Need Them
A circuit breaker can sit closed for years without ever being asked to operate. Dust, dried lubricant, worn contacts and aging trip units can all prevent it from opening correctly during a fault. Regular inspection and testing confirm that each breaker will protect people and equipment as designed.
EBS provides circuit breaker services for facilities that want to extend equipment life, meet maintenance programs or replace obsolete breakers without replacing an entire switchboard or switchgear lineup.

Circuit Breaker Services FAQ
- How often should circuit breakers be tested?
- Frequency depends on the equipment, environment and how critical the loads are. Many facilities follow manufacturer guidance and maintenance standards such as NFPA 70B.
- What is a breaker retrofit?
- A retrofit replaces an obsolete breaker with a modern one adapted to fit the existing cubicle, avoiding replacement of the entire lineup.
- Will testing require a power shutdown?
- Most breaker work requires de-energizing the equipment. We help schedule work to limit the impact on your operations.
