mxslick: I believe I have seen one of those CSP transformers around here, but they are getting rare. The one I saw had an external arrester but no cutout, although there was some form of switch handle on the side of the transformer itself, and as bizarre as it sounds, there was a red indicator light that was on all the time as well. Not sure if it had a secondary breaker either I only saw one switch handle mounted on the trans.
