I used a Webrelay and then installed a 25 amp contractor in 4 by 4 handy box with SO 10 ga in and out. 12 volt coil so on my other 12 volt devices had it anyway!

Yes, a bunch of guys have been ¡°rolling their own¡± using 240 volt contactors with either 12 volt or 120 volt coils.

Important Safety tip! If you are unsure or just want to be safe, you can have a licensed electrician make it for you. Be safe!

I use a 12V relays and a P&B DPST relay.

They look sort of like this

Thanks Mike,

Looks like I'll be rolling my own.

I want to trigger this from my RPi with 3.3vdc. I am not envisioning this. Anybody got a circuit in their head?

These devices are designed to be switched from a GPIO pin. ?I have several.

They safely control 120VAC loads, with overload and surge protection. ?You could in turn use it to switch a 240 VAC load on/off through a two pole contractor, with 120VAC coil.

That's perfect. In fact. I'll just run the amp from 120. It only requires 240 when running CW. I won't be running CW when remote.

For the time being. I decided to run the amp on 120VAC. I used this device. Eventually I'll run a 240VAC relay with 120VAC coil.
