Yes I think you're right - I've hunted around on the online support some more and found that the minimum ON time is 0.1 second, so then it's just a question of how responsive the circuit breaker is I guess... You're right though - this approach would create the possibility of accidentally turning it...

Yeah, that's why I'm asking - obviously if for example they are on for 2 seconds then off for 2 seconds it's without a doubt going to overload the breaker, but if the PWM is sufficiently rapid then the load will in effect become smoothed out to an average load. The question then is how often such sw...

Hi, I'd like to install heating elements with excess wattage, then run them at a lower duty cycle in order to avoid scorching of wort. For example, I would like to run 2x5500 W elements on a 25A circuit breaker, but use a duty cycle of only 40%. Obviously run at full capacity these two elements will...
