What Is a Panel Upgrade (and when do you need one)?
- Definition (simple): A panel upgrade replaces your existing service equipment (meter/main and/or main breaker panel) to improve capacity, safety, and reliability.
- Common triggers: EV charger or heat pump added, frequent breaker trips, limited spaces for new circuits, outdated/unsafe equipment, or remodeling/ADU plans.
- Goal: safe power delivery today with room for tomorrow.
If your panel is healthy but you need more circuits in one area (garage/ADU), a Sub-Panel Upgrade in Los Angeles can be smarter than changing the entire service.

Understanding Panel Upgrade starts by ruling out cheaper, safe options:
- Repair — Replace failed breakers, fix loose terminations, correct labeling/bonding.
- Subpanel — Add circuits where you need them while keeping the main panel as-is.
- Full Upgrade — When capacity is too small, the panel is obsolete/damaged, or you’re electrifying (EV + HVAC + cooking).
Tip: If your load calculation shows you’re near or over capacity—or your panel has safety issues—go straight to upgrade planning.
Your Equipment Choices: Meter-Main Combo vs Main Breaker
Choosing Meter-Main Combo vs Main Breaker affects price, layout, and inspection speed.
- Meter-Main Combo: Meter socket and main disconnect/breakers in one enclosure. Clean look, fewer boxes, often ideal when relocating equipment or meeting new clearance rules.
- Main Breaker Panel (separate meter): Flexible when the meter must stay where it is, or when a subpanel layout already makes sense.
Either path can be code-compliant; the right choice depends on space, local rules, and your future loads.
What Exactly Happens During an Upgrade?

Safety & Code Notes
- Listed parts only: Use breakers and accessories listed for your panel model.
- Grounding & bonding: Crucial to fault clearing and shock protection.
- Clearances & labeling: Inspectors look for working space and legible circuit directories.
- Future-proofing: If EVs, heat pumps, or an ADU are on your roadmap, design for them now to avoid re-work later.
