Hi, I keep tripping the house when I wire the astute controller to the geyser circuit breaker. The geyser has a 20A breaker. I take from the load of the breaker to the top of the controller L then a N to the neutral bar. I then take load of geyser into the bottom of the controller, switch power on and it trips. I then went and bought a 30A breaker for the geyser and the same thing happens. I have tested the astute controller by wiring it into the 10A light circuit breaker and it works without tripping. Any advise would be appreciated.
