Here's my imaginary panel (hey, better than an imaginary girlfriend; how's that for topical humor) for e-BIAB. 12x12x6 plastic box painted black, 240v 30a input, Auber illuminated push buttons, PID and timer. Power button closes a contactor energizing the panel, Element button closes a contactor enabling the element, Element On light illuminates when the element is being fired, "Time Quiet" and "Temp Quiet" buttons use NC contact blocks and are illuminated when depressed such that the alarm has been disabled for the function.
