Power Share Switch

[scottz]

If found this today; what do you suppose they are using it for?

I did a web search and this is what it does:

"Power Share Switch (PSS) provides the capability to wire two appliances to a
single circuit breaker. The Primary appliance never losses power. The Secondary
appliance is allowed to run as long as the Primary is not drawing current. Power to the
Secondary appliance is turned off whenever the Primary Appliance is drawing current."

Friend had a 2008 3295RK with a switch that in one position he could use the convection/microwave and the other position he could use the fireplace. But I don't know that it had that "sharing" feature.

I did a little test today and found that the Power Share Switch is fed by the breaker for the bedroom air conditioner. So, one of the loads is the bedroom AC; I assume it is the primary load (never had it cut out) but don't know for sure. No idea what the other load is (not microwave, not fireplace). I can't find anything that does not work so I'm thinking it might be outlets. Guess it will become apparent one of these days.

Can't imagine one of these things being needed in a rig with a 50 amp panel, especially if it is only rated at 20 amps. Might be useful in a rig with a 30 amp service.

I think they might have used it because they ran out of slots on the breaker panel.

You will need one if you add a third AC unit.

I never plan to have a washer or dryer; so those two are available if I need them. Not sure where I could fit a 3rd AC anyway.

I found out what the Power Share Switch does. One leg is connected to the bedroom AC, the other leg is not used but wired into the ceiling for a future 3rd AC unit.
