This follows the odd practice of having resistance dimmers in the neutral--which was quite common (no pun intended). I can only imagine one reason: with all those exposed "not dead-front" dimmer plates, was it considered safer to have the dimmer closer to ground potential?Great find!
OKay, I'm less than two minutes into the Salt Water Dimmers video and already have a question only @STEVETERRY , @JonCarter , or @MPowers can answer: Why, in a dimmer, brine , is the hot connected to the lamp and the neutral run thru the dimmer? Presenter says "that's the way it's always been done." Which, as we know, is never a satisfactory (or satisfying) answer.
Jon, that's because... wait for it... people are more stupid, unaware, and disconnected from their situations than ever. People have actually done the stupid stuff all those warning stickers tell you to not do. Seriously.I worked with a lot of resistance dimmer boards in the '50s, '60s and '70s, including a lot pf piano boards, and never worked on one built such that there was much chance of the operator getting in contact with the terminals on a resistance plate, Unless, of course, the operator was incredibly stupid enough to stick his/her hand down between the dimmers and grab something that was obviously hot.. There was a basic assumption at the time that people had at least a small bit of common sense. (This is an item which regulatory agencies nowadays seem to assume that no one has.)
