My idea is to control a series of outside downstream receptacles with one of these XPR-W receptacles. The idea being no outside receptacles will work as long as the XPR is off (people I don't want using these outside receptacles are doing so while I am away). This will keep me from having to do any real re-wiring while still having interior receptacles which are inside the house and on the same circuit as the outside receptacles. The problem, you might imagine, is if someone walks up and plugs a load into one of the outside receptacles or turns a load off/on which is plugged into one of the outside receptacles and kicks on the outside power anyway.
So, you mean there is none of this taking the thing apart and clipping a diode or a trace like in the case of an appliance module?
What kind of current are we trying to defeat here?
Appliance modules allegedly go after 50 mA or higher to know a load is present and below 50 mA to know if a load is not present (this is correct, isn't it?). That would require a 6 or 7 W night light load, correct?
