When it comes to Subpanel Installation, homeowners and businesses throughout Los Angeles County trust Armo Electric USA for professional results.
Your electrical panel is the heart of your home’s power distribution system. Subpanel Installation is one of the most important electrical upgrades you can invest in — it directly affects your home’s safety, the reliability of every circuit, and your ability to add modern electrical loads like EV chargers, home offices, and high-efficiency HVAC systems.
Panel upgrades involve coordination with your utility company for the service drop, installation of a new meter base if required, and careful circuit mapping to maintain power to critical systems during the changeover. Our electricians create detailed circuit directories and label every breaker clearly — something that’s invaluable during emergencies or future service calls.
We also evaluate the need for whole-house surge protection (required by NEC 2020 Section 230.67), AFCI breakers for bedrooms and living areas, and dedicated circuits for high-draw appliances. A properly planned panel upgrade anticipates future needs — adding capacity for solar, battery storage, or additional EV chargers down the road.
Panel work is the most critical electrical service there is. Our team has upgraded over 2,000 panels across LA County — from 60-amp fuse boxes in 1940s homes to 400-amp services for modern estates. This isn’t a side job for us — it’s our specialty.
Every panel upgrade we perform is fully permitted and inspected. We handle the paperwork, schedule the inspection, and ensure first-time pass rates above 98%. No shortcuts, no under-the-table work.
Our father-son team has seen every panel brand, every wiring condition, and every surprise that old homes can throw at you. That experience means fewer surprises, faster completion, and work that stands up to any inspection.
We don’t just solve today’s problem — we design for tomorrow. Every panel upgrade includes capacity planning for EV chargers, solar, battery storage, and home additions. You won’t need another upgrade for decades.
📋 Recent Service Call — Torrance, CA: We were called to a 1960s home in Old Torrance where the homeowner was getting denied for homeowner’s insurance. The reason? A Federal Pacific Stab-Lok panel — one of the most dangerous panels ever manufactured. Testing showed that 3 out of 12 breakers failed to trip under overcurrent conditions. We replaced the entire panel with a new 200-amp Square D unit, added whole-house surge protection, and the homeowner had their insurance approved within a week. The old panel had been a ticking time bomb for 60 years.
