  • Reasons for rain leakage in the electrical distribution box wiring

    Reasons for rain leakage in the electrical distribution box wiring

    Moisture can damage insulation in underground cables. This may lead to short circuits. This makes your circuit. Rainwater can make its way into outdoor outlets, exposed wiring, or even into poorly sealed electrical panels. While your circuit breakers are meant to protect you by shutting off power during faults, they can also be triggered by moisture where it shouldn't be. Once water gets onto an electrical panel, it can cause many problems, including corrosion, fire, and breaker malfunction.
