HOWEVER: these are NOT 180 degrees out of phase. It is more like 120 degrees. I am taking it that America also has 3 phase supplies, rather than 2. I liked your article. It had a lot of good pointers for others. It may be a good idea to add a red indicator between neutral and ground for the two i...Read more -
How To Wire A New Garage For Electric-Car Charging: What You Need To Know | Circuit Breaker Parts
Getting reasonably priced SSRs that are trustworthy seems almost impossible. A 40A TRIAC costs $34.

I understand it’s only about 20hz, which is why it gives you that interesting jiggly feeling instead of a good Wack like mains power at 50/60 Hz does.
