Electrical Panel & Service Upgrades
100A → 200A → 400A · Chicago & North Shore
Out of breaker slots, dimming lights when the AC kicks on, or still running a 1960s fuse box? Almighty Electric LLC modernizes older 100-amp and fuse panels to robust 200A or 400A main service across Chicago and the North Shore — clean, code-compliant, and fully permitted.
What a Panel Upgrade Includes
- New 200A or 400A main breaker panel with arc-fault (AFCI) and GFCI breakers
- Meter socket and ComEd service-entrance upgrade coordination
- Whole-house surge protector and dedicated EV / appliance circuits
- Removal and safe disposal of hazardous Zinsco, Federal Pacific (FPE), or Pushmatic panels
- Full municipal permitting, inspection scheduling, and guaranteed code compliance
- Grounding and bonding upgrade to current NEC standards
Why Upgrade Your Electrical Panel?
Power Modern Appliances
EV chargers, heat pumps, tankless water heaters, induction ranges, and mini-splits all demand more amperage. A 200A panel gives you headroom without tripped breakers.
Eliminate Fire Hazards
Federal Pacific and Zinsco panels are known to fail to trip during overloads. Replacing them removes a leading cause of electrical house fires in older North Shore homes.
Increase Home Value
Buyers and home inspectors flag outdated panels. A modern, permitted 200A service is a selling point that speeds closings and supports smart-home and EV upgrades.

Panel Upgrade Questions, Answered
Q.How do I know if I need a 200A or 400A panel upgrade?
If you're adding an EV charger, heat pump, or second AC unit, or your 100A panel is full of breakers, you likely need 200A. Large homes with multiple high-draw systems, a subpanel, or a standby generator may need 400A. Use our free load calculator above, then call us for a confirmed on-site assessment.
Q.How long does an electrical panel upgrade take?
Most residential 100A-to-200A panel swaps are completed in a single day, with the power off for roughly 4–6 hours. Service upgrades that involve the meter and ComEd may add a second short visit for the utility reconnect.
Q.Do you pull permits and handle the inspection?
Yes. Almighty Electric LLC pulls every required municipal permit, schedules the village or city inspection, and guarantees the work passes. You never deal with the paperwork.
Q.Can you replace a Federal Pacific or Zinsco panel?
Absolutely — and we recommend doing it promptly. Federal Pacific Electric (FPE) Stab-Lok and Zinsco panels have a documented history of breaker failure and are a leading fire-safety concern in older Chicago and North Shore homes.
