Oooooooooops. Well, chalk that one up as a learning experience. And
thanks to all who corrected my inaccurate description of transformer
operation.
When I designed my DIY heating cables, I sought out a transformer that
included a rectifying diode to convert the output to DC. I was under the
impression that this was standard practice (for the reasons mentioned in my
earlier post).
I would highly recommend that anyone doing DIY heating cables use a DC
supply voltage. And I'll reiterate Steve Pushak's message: Safety First.
