How safe is it to use a SSR to control power to a spa? Or use a relay?
NiHaoMike:
Check if there's an existing control relay you can tap into. Other than that, a contactor controlled by a smart plug is one very easy way to automate large loads.

They do, but 2 day shipping is free. I wonder what Digikey and Mouser would charge. Don't they have a minimum order size? I think they would charge more than $10 just for the shipping.

I sometimes wonder what the point is of spending my time to give someone technical advice, only to get dragged into this sort of crap. :palm:
Buy it where you want.

I have and there is not one relay. There are at least 3. One for each of the two pumps and another for the heater. The electronics have "settings memory" so if power is lost the settings are retained. (My last tub the settings were lost.)

You are upset because I'm not buying from one of the two vendors you suggested? My post was for advice on using an SSR vs a relay. Did you even answer that question?
Gyro:
I'm not upset, just pissed off. My only point was that you should buy one with a genuine approval. I'm in the UK, I don't use either.... and yes I did - I said use a contactor not an SSR. Go back and read your own thread!
