if 2 relays shared the same power cable (both switching on at the same time) would you effectively get twice the wattage (keeping the voltage static)..
I'm guessing yes, but could you guarantee they switched together? Split second's delay on one, and the other's got the full load.
good question!
um... yeah, not such a good idea, unless the load could be controlled until both were switched on fully....
unless the load could be controlled
Like with another relay 8)

Its a very good question - probably depends on whether AC or DC, high voltage or high current. The
contacts have to cope with switching events, which as pointed out won't share equally between the relays
due to mechanical differences in the timing, but also contacts have to handle the on-current without
getting too hot, and sharing here is going to work well.
I suspect you need to be conservative and say 2 relays = 1.5 times the current (if lucky). Finding a bigger
relay is probably best.
