Main Panel Upgrade

Project Location : El Cajon, CA

Project Overview

Improving Safety, Capacity, and Code Compliance

Benson Electric upgraded a residential main electrical panel in El Cajon following an HOA-mandated safety review. The existing panel contained Stab-Lok and Pushmatic breakers—now recognized as major fire hazards. Our team replaced the panel with a solar-ready 200-amp system and brought the home into full NEC compliance.

What We Did

Old Panel Removed

  • Hazardous Stab-Lok/Pushmatic panel removed

New System Installed 

  • 200-amp main panel, solar-ready
  • Two new ground rods added
  • Cold water system bonded to electrical system

Key Discovery:

  • Home was missing proper bonding, a critical safety flaw

Why Bonding Matters

We ensured the home met NEC Article 250 standards. Proper bonding:
  • Prevents electric shock from ungrounded metal systems
  • Reduces fire risk from potential arcing
  • Ensures system-wide electrical continuity and safety
  • Is legally required for residential properties

One-Day Installation Timeline

We coordinated with SDG&E for a seamless, same-day upgrade
  • Morning: Power disconnected, old panel removed
  • Afternoon: New panel installed, grounded, bonded, and inspected
  • Evening: System approved and power restored

Why This Upgrade Matters

This upgrade offers the homeowner:
  • Fire hazard elimination
  • 200-amp capacity for modern energy use
  • Future-ready system for solar and EV chargers
  • Increased home safety and value
