- Certified to UL 916 standards as a dedicated Energy Management System
- Performs automatic load calculations every second to keep panel usage under the 80% threshold
- Weatherproof NEMA 3R enclosure certified for indoor and outdoor installations
- Flexible current sensors fit easily inside space-constrained electrical breaker panels
- Configuration relies on manual onboard DIP switches rather than dynamic software provisioning
- Auxiliary telemetry and remote reporting require an active internet connection
Overview
The Stepwise Tap is an intelligent dynamic load manager and residential energy management system architected to optimize electrical service capacity without requiring costly main panel upgrades. Certified under UL 916 standards, the system continuously samples panel capacity using high-precision flexible current sensors designed specifically to navigate cramped breaker enclosures. Operating on a rapid one-second calculation cycle, the internal controller autonomously manages high-draw secondary loads—such as Level 2 electric vehicle chargers, heat pumps, water heaters, and pool pumps—to maintain aggregate panel demand safely beneath the mandatory eighty percent operational threshold.
From a physical and environmental standpoint, the Tap is housed in a rugged NEMA 3R enclosure engineered for seamless deployment across both indoor utility rooms and harsh outdoor electrical environments. The unit operates via completely passive thermal dissipation, generating zero audible acoustic noise and eliminating mechanical points of failure through solid-state sensing and control circuitry. Configuration is achieved directly on the control board using dedicated DIP switches, ensuring dependable baseline operational thresholds without strictly relying on cloud communication for core electrical safety, while onboard internet connectivity enables auxiliary monitoring and diagnostics.
