The main electrical panel is the heart of the electrical supply system in the home. Once electricity has been pulled from the street, into the home, it hits the main electrical panel and is then divided into specific branches of circuitry to supply power to household appliances, lighting, receptacles, heating, air conditioning, etc.  Read on to find out when it might be time to upgrade the home with a larger electrical panel or a sub-panel.


Each electrical panel has a finite amount of amperage available. If a homeowner requires additional amperage they can either replace the panel with a larger one, or install a subpanel in a different part of the home.

Subpanels are typically installed during remodels or when building an addition. That’s because it’s more convenient and cost effective to connect a subpanel to the main electrical panel with a single wire, rather than running multiple wires for each individual circuit back to the main electrical panel. Especially if the main panel is flush mounted to the drywall and would require minor demolition and repair.

Overloaded circuits

Each circuit in the electrical panel or subpanel is protected by a fuse or circuit breaker which allows a specific amperage of electricity to flow to the receptacles. If the flow of electricity is continually interrupted by tripping circuit breakers or the homeowner notices flickering lights, it could indicate that the circuit is carrying too heavy of a load. If that is the case, the problem should be diagnosed immediately by a trained, professional electrician as this presents a series safety hazard.
