Use a ohm meter and check the case metal to all three contacts on the triac. Any resistance reading, on the low ohms setting, means that the case is not isolated. If it is not then you will need a ceramic or mica insulator and plastic or nylon spacers so the mounting screws dont short to the case. The triac you are replacing is a Teccor triac and you could probably get a free sample from a company called Omni-Pro in Texas, they are a major Teccor distributor. Call 972-713-9000 and ask for Brenda.
