Getting Started

  • The Stepwise Tap is a UL-listed dynamic load management device that sits between the panel and high-load appliances. It adjusts appliance draw in real time to prevent overloads.

  • Tap works with 100–200A panels. It’s charger-agnostic and non-proprietary—use it with Wallbox, Tesla, Grizzl-E, Emporia, and more.

  • Stepwise Tap is a UL-listed Energy Management System. When properly installed, it allows you to omit the EV load from NEC load calculations per Article 750.30(C).

  • Stepwise offers real-time dynamic control, not just on/off logic. Plus, it's American-made and trusted by code inspectors.

  • Because your customers want options. Stepwise Tap helps you win more bids by offering a faster, cheaper, code-compliant solution.

Using the Tap

  • EV chargers, hot tubs, pool pumps, resistive HVAC, water heaters—anything high-load. Reach out if you have a unique use case.

  • Install Tap between the panel and appliance. Connect the CTs for panel monitoring. Full installation guides are available at Stepwise Docs.

Troubleshooting

  • Check for voltage on the LINE side of Tap. Also confirm your wiring matches the install guide.

    See support diagram here.

  • Make sure Tap’s current settings match the panel and charger specs. See our Breaker Trip Guide.

  • Check if dynamic control is active and load availability is sufficient. Confirm EVSE compatibility with dynamic load management.

  • Ensure Tesla is linked via OCPP and that Wi-Fi is connected. Reboot both Tap and vehicle if needed.
