	*Without power, heat bed was at 120V, and I got a shock even though the bed is on the GFCI! Did I hit the rare condition where a shock is possible? I touched the top plate of the heat bed and the frame of the printer, both of which are isolated from each other. What is happening? And does a ground on the frame and on the heat bed fix this? THis calls for some experiments to verify correct behavior. For example, if there is a short in the bed, the GFCI should trip via overcurrent, or upstream breaker should trip if on the grid. Test 1: short on GFCI ('fork' into both sides of the gfci): breaker in power strip tripped immediately.		*Without power, heat bed was at 120V, and I got a shock even though the bed is on the GFCI!
