What is the Difference between a Subpanel and a Full Service Upgrade?
When evaluating service options for your electrical system, it is important to understand the two primary ways to increase your home’s capacity:
- Full Panel Replacement: This involves swapping your entire existing electrical box with a new 200-amp unit. This is often recommended for older homes, particularly those built before 1960 that may still use 60-amp fuse panels. A full replacement ensures your wiring is up-to-date and provides the best foundation for future smart home integration.
- Capacity Upgrade: Alternatively, a capacity upgrade (sometimes referred to in the context of service options) increases the amperage of your system while keeping the existing panel enclosure, provided that current electrical codes permit doing so.
Both options require working with licensed and insured electricians to handle the necessary permits, load calculations, and coordination with local utility providers like Southern California Edison or Pasadena Water and Power. Choosing the right path ensures your home meets all safety regulations and is prepared for modern technology, such as EV chargers and smart lighting.
