It never dawned on me that “sparky”, my adventurous electronics engineer husband, was out looking for electronic circuits in the mountains of WVa. When he took off with our grandnephew on his side-by-side four-wheeler I figured they were just going for a joy ride in the mountains. It wasn’t until I saw the pictures it became obvious why he didn’t tell me what they were up to.
I never would have agreed for him to climb to the top of a 300 ft tall windmill in search of PTC heaters!
The view was spectacular and unique opportunity to see the world from an unusual vantage point. It was good that his guide had enough sense to shut down the 690-volt power coming from the windmill while they were inside exploring. Sparky probably would have peeked into all the cabinets with the power still on. I still don’t know what a PTC heater is but he showed me pictures of something sticking out the side of a fan heater with wires on it. He explained that this was how not to supply heat to a control cabinet. Seems that the company he works for has better-manufactured solutions for the problem.
