Panel Upgrades & Replacement
An outdated electrical panel is a safety risk and a bottleneck for modern living. ARC Electric provides expert panel upgrades and replacements for homes and businesses throughout Milpitas, San Jose, and Santa Clara County.
Signs your panel needs upgrading.
Frequent Breaker Trips
Your panel can't handle modern electrical loads. Trips become more frequent as demand grows beyond the panel's rated capacity.
Flickering or Dimming Lights
Inconsistent voltage delivery from an aging panel causes noticeable lighting fluctuations throughout your home or business.
Panel Is Over 25 Years Old
Older panels — including some Federal Pacific and Zinsco models — may have documented safety issues and are candidates for replacement.
Burn Marks or Smell
Scorch marks inside the panel door, or a burning smell near the breaker box, are immediate warning signs requiring professional attention.
Adding New Appliances
EV chargers, home additions, hot tubs, and large appliances often require a panel upgrade to support the additional load safely.
Fuse Box Still in Use
Original fuse boxes found in older homes are a safety and insurance liability. Upgrading to a modern breaker panel is a critical improvement.
