Electrical Systems work very much like water systems. Much like your sinks,tubs, pipes, and toilets have seals at all the connections, so does your electrical system. Over time with heating up and cooling down, oxidation, and use the panel in your home becomes less effective. As this happens, not only do we lose protection from the Over Current Devices ( Breakers) , we also tax (Drag down) all the components attached to it.
Questions to ask yourself?
- Is my Panel over 20 Years Old?
- Are there Ground Fault / Arc Fault Breakers in this Panel?
- Does my Panel have Glass Fuses?
- Do I have a Main Breaker at My Meter base?
