When you set up a test rig in a lab environment you design it for the highest power you MIGHT need. The 3-phase-triac December test used 360W The 1-phase-triac March test used 322W A 38W difference? Come on, now. I haven't done the arithmetic, but that looks suspiciously like the ratio between phase1-phase2 and phase1-ground ? You CAN get wimpy single-phase dryers, but I wired my house for the recommended three-phase. > He *did* redesign it. He stopped using the triac, and replaced it > with a different control circuit.

He reprogrammed the controller, and changed the triac wiring from phase1-phase2 etc to phase1 ground. I don't call THAT a re-design.
