Considerations

  1. Have your electrification plan ready so you know how much panel amperage you are saving for each future need (heating, water heating, 240 V charging, cooking, drying).
  2. Actively participate in device and appliance selection with the contractors.
  3. Contractors will need to know the maximum nameplate amps or watts you are allocating for the device, and if the circuit is installed.
  4. Install circuits and space for controls if needed.
  5. Think of the EV as the “shock absorber” in the plan.
  6. 120V charging is common.
  7. Don’t put yourself into an expensive corner by picking incorrect equipment and not planning your electrification. You could end up upsizing your electrical panel when you do not need to.
  8. Don’t wait until your water heater, furnace, dryer or cooktop fails to install circuits. Be proactive, pre-wire for electrification.
  9. Don’t install power hogs, like 50-amp EV chargers.
  10. Don’t oversize your HVAC equipment “just to be safe.”
  11. Don’t undersizing your heat pump water heater.
