Electricians need a reliable method to detect if the surface of a service enclosure is energized when there is no reference to ground nearby, particularly on corner-grounded delta systems with potential grounding errors.

No non-contact, ground-reference-independent tool exists to verify enclosure energization in isolated locations like rural areas.

App Concept

EnergizeGuard Pro

A handheld, non-contact voltage detector that works without a ground reference by measuring capacitive coupling or electric field strength relative to a known earth potential via a built-in earth stake or wireless reference. It provides a clear visual and audible alarm if the enclosure surface is energized.

Key Features

No ground reference required – uses internal capacitive sensor or deployable earth stake
Visual and audible alert for presence of hazardous voltage
Rugged, weatherproof design for field use
Auto-calibrates for different system voltages (e.g., 480V)
Rechargeable battery with long operational life

Target Users: Electricians and lineworkers servicing three-phase services in remote or rural areas

Revenue Model: $199 per device, optional $49/year calibration service
