FAQ
Q: Can I install a load center myself, or should I hire a professional?
A: Yes it is technically possible to install a load center yourself. But it is highly recommended to hire a licensed electrician due to the complexity and safety risks associated with electrical installations.
Q: What should I do if my load center trips frequently?
A: Frequent tripping of a electrical distribution board could indicate several issues, like an overloaded circuit, a faulty breaker, or a short circuit in the wiring. First, identify if a specific circuit is causing the problem and check whether any appliances on that circuit are using more power than they should. If the issue persists, immediately consult a licensed electrician to diagnose the root cause. Do not attempt to reset the breaker repeatedly, as this can damage the system and increase the risk of fire or electrical hazards.
