Need a cheap, simple device to prevent auto-restart of a subpanel after a power outage or generator transfer switch activation, to avoid overloading backup generator.
Existing anti-restart solutions are either per-equipment (costly for multiple loads) or expensive industrial enclosures; no cheap, simple option exists for a whole subpanel.
