    This will trigger your triac on, but randomly and that may cause you problems. Because of the heavy current load, you may want to zero-cross trigger your triac; (trigger when voltage or current is zero). Also, you may want to soft-start your load; (increase power gradually). Lastly, it is advisable to add optical isolation between trigger and load to keep noise problems to a minimum.

    You will find some circuits on this forum that will lead you in the right direction, but without knowing something about the load, you will need to do the development work on your own. You will learn a lot by doing that, so proceed...
