Know what to look for
Does your panel need evaluation?
These common conditions can signal that it is time to assess the home’s electrical capacity before adding new equipment or circuits.
No Available Breaker Space
A full panel may not have room for new circuits or equipment.
Adding an EV Charger
The proposed charger load must be evaluated against the home’s existing capacity.
Adding Solar or Battery Storage
Panel condition, busbar rating and service capacity may affect system design.
Installing a Heat Pump
New heating and cooling equipment may add a significant electrical load.
Planning a Major Remodel
Kitchens, additions and other projects can introduce substantial new electrical demand.
Service capacity
100-amp versus 200-amp service
Many older homes were designed around different electrical demands than today’s EV chargers, heat pumps, solar systems and batteries. Service size is one part of the evaluation; connected loads, equipment condition and available breaker space matter too.
100
Existing service
Existing 100-Amp Service
- May be adequate for some homes
- Capacity depends on existing connected loads
- Available breaker space must be evaluated
- New electrification loads may require additional planning
200
Potential upgrade
Potential 200-Amp Upgrade
- Provides additional service capacity
- Can support additional electrical circuits
- May help prepare for multiple electrification upgrades
- Requires utility, permit and load-calculation review
A 200-amp upgrade is not automatically required. EL-FI Homes recommends the service size supported by the actual load calculation and project requirements.
Plan systems together
Panel readiness for home electrification
Adding major electrical loads at the same time can make coordinated design, permitting and installation more practical. EL-FI Homes can evaluate how each proposed system relates to your home’s existing service.
Solar
Panel rating, busbar capacity and existing electrical configuration are reviewed during solar design.
