I used a triac circuit design form littlefuse AN1003.16 Phase control permanent magnet motor. I connected it up to 115v ac and measured the outut on a multimeter. I measure approx 100v before the triac when short circuit and blow a trip.
Not sure what I have done wrong, does it matter which way MT1 and MT2 are connected? is the circuit correct?
