I know about the circuit breaker/peak volts, but never knew about that feature of SSRs.
You learn something new everyday!
This would be my first use of a SSR, so I just want to make sure I get it right.
I like to try and avoid puffs of smoke on the first power on!
I've been doing some calculations, and the SSR should be capable, unless the secondary side of the transformer has too big a load. It is borderline given it's going to be a 22,000uF capactitor peaking at 77V charging from zero volts, but going by my rough calculations and the datasheets, the bridge rectifier is going to die before the SSR.
If the BR does die, then I'll add an aditional relay/resistor to reduce the Bridge Rectifier load briefly until the relay closes and bypasses the resistor (a suitable relay will have a delay of around 20ms, which should be enough to overcome the initial surge)
