Kyle Kubs Posted June 21, 2012 Report Share Posted June 21, 2012 Hey Gents. Have a new mystery today. Have three main panels over this hot gutter and under is a bank of 24v transformers. And another one next to a sub panel in the attic. Now I've heard some old houses once had DC lighting systems, never seen one but heard of them. But this is a 1962, very modest split level. Seems to be an anomaly, the original owner was apparently an electrician. I'd say he was an industrial electrician by the looks of things. There are three more panels in other places. But the only thing I can figure is that these must be for DC lighting. Didn't take the time to break out the multi-meter, it was just "one of those" inspections and way too much left to do. All the wiring is still 14 ga. so it shouldn't be too hard to convert everything, since most of this will be ripped out anyway. Any thoughts?

Marc Posted June 21, 2012 Report Share Posted June 21, 2012 I see a bank of what seems to be DPST relays immediately below the gutter. Marc Quote Link to comment Share on other sites More sharing options...

Marc Your right, there are switch contacts on the top, but what could this be for? And what is the point if the signal wire and load wire are the same gauge? Nothing else anywhere in the house gave any impression of being other than a normal electrical system. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted June 22, 2012 Report Share Posted June 22, 2012 We think you're looking at a low voltage switch system with 120 vac still going to the light fixture. Only the switches would be 12 vdc, and they activate those high voltage relays. There's no need to rip it all out, unless replacement parts get scarce.

kurt Posted June 22, 2012 Report Share Posted June 22, 2012 I'd rip it all out...it looks like a bunch of StabLok panels. Quote Link to comment Share on other sites More sharing options...
Marc Posted June 22, 2012 Report Share Posted June 22, 2012 Kyle, out of curiosity, can you get that bulletin # off of the relay? Marc Quote Link to comment Share on other sites More sharing options...
Kyle Kubs Posted June 26, 2012 Author Report Share Posted June 26, 2012 Hey. Sorry to question & drop out of sight, again... The extended weekend from HELL on top of being WAY too busy lately. Yah, Kurt, their all Stablok panels. Six of them actually. They won't be there much longer. Things weren't making sense to me about the relays cause none of the lights switches were low voltage switches, until I remembered the listing agent saying something about the house initially being set up for electric baseboard heat that was never finished, but changed to F/A which is the current heating system. There were electric/line voltage, thermostats in several rooms and that now makes a bit more sense. I'm not used to relays in residential construction. Use them plenty in electronics and high amperage industrial equipment, automotive electrical but they look a lot different than these. Marc, the Bul. # is 700.
