Compare charging energy needs and available hours, review service and circuit limits, then retain configured settings, installation checks and results.
Record the vehicle’s AC acceptance, realistic battery energy to add, the hours available and any expected load-sharing limits. Compare a few documented EVSE current settings at the actual supply voltage using supported efficiency assumptions. Establish a practical charging requirement before assuming that the largest available setting is necessary.
Have the installer assess the existing service and complete the applicable load calculation, including the proposed EV charging arrangement. Reconcile the approved demand values and leg loads, then check actual panel spaces and allowed breaker positions. If considering energy management, have its supported topology, controls and commissioning requirements designed explicitly.
Use the installation manual for the exact EVSE and choose a permitted configuration and actual breaker. For the ordinary continuous-load case, compare 125% of configured maximum AC input with that breaker and the independently verified protection ceiling. Review conductor material, cable type, terminal temperature, current-carrying conductors and any required protection or disconnects.
Measure the intended cable/raceway route, equipment position, cable reach and access. Review impact protection, weather exposure and the model’s mounting instructions. Calculate voltage drop using actual conductor data, check ordinary conduit fill where applicable and compare full installed quotes including civil work, permits and inspection.
Use an authorized installer to complete the specified circuit, connections and required tests. Have the maximum circuit/current setting configured through the manufacturer’s commissioning process and record it. Verify any energy-management sensor configuration and behavior with the approved design, then retain permit and inspection outcomes.
Record a representative session’s available hours, delivered energy and relevant conditions. Compare the observed result with the charging-window estimate and distinguish vehicle limits, taper, temperature and sharing from an installation fault. Keep settings, manuals, installer contacts and the saved cases for future changes.
Use Charging energy and time window to compare battery energy, vehicle acceptance, AC power factor, conversion efficiency and available hours. · Use EVSE circuit current check for the ordinary 125% case and inspect both lower breaker and upper protection limits. · Save the final configured maximum AC current and circuit-rating case using installed equipment values. · Update the charging-window case with supported observed efficiency/current and retain the original estimate for comparison.
Reconcile the documented demand categories and split-phase leg allocation; use the separate space inventory for actual device quantities and occupied positions.
Screen the finite manufacturer chart using required ampacity, the actual breaker, correction factor and limiting terminal column; review every failed condition.
Select only from the exact approved breaker catalog using noncontinuous and weighted continuous current plus the verified protection ceiling.
Use the AC mode with actual conductor R/X, operating current, length, phase arrangement and chosen equipment/design limit; evaluate relevant line-to-neutral paths separately.
Total outside insulated-conductor/cable areas and compare full internal raceway areas using the ordinary count-based fill rule, applied once.
Count actual continuous cable runs, specified cable type, slack and parallel cables, then allocate usable stock rolls; the tool does not produce a wiring diagram.
Compare actual installed quotes, deposits, chosen contingency and confirmed reimbursements; retain the scope and date of each case.
Keep the dated equipment list, document references, responsible installer and unresolved decisions; export the record with the calculation cases.

The cited Wall Connector manual illustrates discrete current/breaker configurations and terminal-dependent conductor requirements. Apply the manual for the installed model, not this example to all EVSE.
Retain separate load-category calculations and the actual approved EV charging arrangement. Reconciliation arithmetic does not decide code eligibility.
The vehicle’s AC acceptance and EVSE configuration can differ. The charging-time estimate also needs losses and actual operating conditions.
A lower permitted current can meet an overnight need; calculate the actual energy window before choosing a configuration.
Record the installed maximum setting and any load-management configuration with the one-line diagram.
