- For Safety Reason......Each leg should be fused with fast acting fuses.
- For Safety Reason..... Light bulbs should be enclosed by a wire mesh screen.
Bulbs can and will explode when least expected.
- Use 300-watt bulbs as Mark stated.
If you use bulbs of lower wattage, you may not draw sufficient current to satisfy
the Ih (Holding Current parameter) of the SCR's, and they will turn-off.
- Strip heater elements could be used instead of light bulbs. Just be sure that they are rated correctly for voltage and minimum wattage required.
