ELECTRICAL PANELUPGRADES & HEAVY-UPS
Your electrical breaker panel is the central heartbeat of your home's power distribution. If your San Antonio property still operates on an outdated 100-amp service, obsolete fuse box, or hazardous panel brand (such as Federal Pacific Electric or Zinsco), your system is vulnerable to catastrophic overloads, arc faults, and electrical fires.
SA Electrician specializes in turnkey 200-amp and 400-amp electrical panel upgrades (heavy-ups). We replace degraded busbars, upgrade service entrance cables, install dedicated grounding rods, and add whole-home surge arrestors—ensuring your home safely powers modern EV chargers, high-efficiency HVAC systems, hot tubs, and smart home appliances.
