Over 100 of the T&D Guardian's end-user circuit breakers participated in our recent medium-voltage (5-15kV) air-magnetic breaker maintenance survey. Despite an increased trend towards outsourcing of services, over 90% of our survey's respondents do all or at least some of their medium-voltage circuit breaker maintenance in-house.
