  • Corrosion is typically caused by water damage in a subpanel. Like all water damage, especially water damage that intersects with wiring, it should be addressed by a professional like your local Mr. Electric.

  • Improper bonding is a professional way to say that the wiring was installed wrong. This can lead to serious issues, including electrical fires, and needs to be addressed immediately by an experienced electrician.

  • A double tap is when two wires are attached to a single circuit breaker, a setup it wasn't designed to handle. This creates loose connections, which can lead to overheating, arcing, and poses a serious fire hazard.

FAQ

  • If you’re considering installing an electrical subpanel for your business, but don’t know if it’s worth the initial costs. Here are some of the benefits of installing a subpanel for your business:

    • Convenience: Subpanels bring circuit breakers closer to where the power is used. This makes it easier and more convenient to shut off the power or reset breakers in case of an emergency.
    • Voltage drop: Subpanels help maintain a steady voltage flow and avoid voltage drops, which can result in a loss of power when wires are run a long distance.
    • Extra capacity: Subpanels add extra capacity to your electrical system, protecting against damages caused by electrical surges.
    • Energy efficiency: Subpanels can help improve energy efficiency for your business.
    • Cost savings: Over time, a subpanel can save you money on your electric bill.

    As you can see, subpanel installation has several advantages for your business. While there is an initial cost for installation, this is offset by improved energy efficiency and lower utility bills. Added convenience and a more consistent power supply are also huge benefits that should not be overlooked.
