In response to last week’s post on knob & tube wiring, we received an inquiry from Scott regarding panel maintenance and replacements. So, this week’s blog is about replacing and maintaining your electrical service panel.
Every building (commercial or residential) has an electrical service panel that controls and distributes electrical power throughout your space. The electrical service panel is sometimes referred to as a circuit breaker panel or fuse box. The electrical panel prevents the overflow of electricity.
Why would you need to replace your electrical service?
If you have a good electrical service, to keep it in good working order, you must maintain it.
Preventative maintenance includes periodic exercise of the operating mechanism. A best practice is to exercise the trip latch mechanism as it can seize due to lack of use. The trip latch can be exercised by primary injection testing or, if it has one, by pushing the Push-to-Trip or similar button (usually red in color). Exercising the trip latch is recommended every 6 to 12 months. Visual and mechanical inspections and calibration tests are recommended to be professional performed every 1 to 3 years.
