Hi guys. As far as I know, contactors are mostly used in industrial motor controls. In my breaker box, after the main switch (3 pole 63A MCB) I thought to wire a contactor beside it, and a 2 way selector to control the coil opening and closing. (Practically pointless because I could trip the whole circuit by the 3 pole MCB, but wiring a contactor is new thing to learn). I cannot wire the selector directly to the main switch since the contacts are only rated for 10A. I have a few questions:
1. What AC type should I pick in residential use? From what I read here: http://www.eecontrols.com/documents/Pages21-30.pdf the appropriate one should be AC-7a? It's hard to anticipate what electronics are coming in the future so I assume of what I have now: oven, ceiling fans, 1.5hp A/Cs, TVs, charger, laptop etc.
2. Is AC3 contactor able to handle AC1 specification? For example if an AC3 contactor is not used with squirrel cage motor, instead with regular lighting circuits, it can handle larger currents? I see many AC3 have 'Ith=AC1=?A' written on them.
My house is running 380V 3ph 50Hz.
Has anyone done this to the house?
