Overloaded Circuit: If the circuit is overloaded with too many devices, it can create electrical noise that manifests as buzzing in your lights after installing a dimmer.

Overloaded circuits can cause significant issues in your home. When too many devices draw power from a single circuit, it can create electrical noise. This noise often leads to buzzing sounds in your lights after installing a dimmer. Understanding this connection is crucial for maintaining a peaceful and functional living space.

When you add a dimmer switch, it may change how electricity flows through the circuit. If the circuit is already near its limit, the additional load from the dimmer can exacerbate problems. The result can be an unsettling buzzing sound that distracts from your home’s ambiance. It’s important to recognize that this buzzing is not just annoying; it may indicate potential safety hazards.

Addressing an overloaded circuit requires careful inspection of your devices. Start by identifying all items connected to the same circuit as your dimmer switch installation.
