Add loads without planning blind

Coordinate major appliances before automatically deciding that a panel upgrade is required.

Important: This tool is a planning index, not a code load calculation. Regulated electrical work belongs with authorized professionals.

Loads and management

EV charging, heat pump, water heating, cooking, spa/sauna and dryer loads should be planned together.

EV charging

Choose location, cable route, useful charging power and load management; verify current incentive conditions.

Battery and solar

Define essential loads, autonomy, instantaneous power, solar integration and islanding.

Heat-pump water heater

Consider room volume, noise, condensate, cooling effect and backup strategy, then compare total cost.

Intervention level

Green — homeowner

  • Inventory nameplates
  • Define needed EV power
  • Define essential outage loads

Yellow — caution

  • Get a load calculation
  • Evaluate load management
  • Coordinate battery/solar/generator

Red — professional / stop

  • Panel/service work
  • New hard-wired 240 V supply
  • Grid interconnection

Legacy conditions and resilience systems

Check these before enclosing, excavating, modernizing or automating an existing system.

Hidden systems and critical interfaces

These checks target costly problems that often appear only after opening assemblies, conversions or changes of use.

Deep retrofit and envelope interfaces

Measure, sequence, drain, dry and verify interfaces before concealing work.

Building interfaces to diagnose before enclosure or replacement

These tools connect structure, water, air, frost, wind and mechanical systems so repairs do not hide the cause.
