Mike Lamb Posted December 7, 2015 Report Share Posted December 7, 2015 This device was attached to an outside electric meter. It is marked as a 1:2 phase saver. I googled the local utility company but did not come up with anything. I am a little familiar with phase savers that supposedly adjust harmonics for more efficient electrical use but have never seen this on a residential property before.

inspector57 Posted December 8, 2015 Report Share Posted December 8, 2015 Don't open it! That lets out the magic juju and it won't work anymore! Thats why they all say do not open. Either that or they know someone will get pissed if they see what is inside and realize they have been snookered.[:-censore Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted December 8, 2015 Report Share Posted December 8, 2015 It's basically a temporary power supply. That house must have lost one leg of its service, so it was only getting 120-volts. This thing connects to the service and temporarily restores 120/240v service. Somewhere on there, it should show a limitation as to how much power it can provide. You usually can't run everything in the house from one of these things. Quote Link to comment Share on other sites More sharing options...

You usually can't run everything in the house from one of these things. Sounds like an autotransformer. It would do exactly what Jim says. It explains the '1:2' designation on the label - it transforms 120 V into 240 V while making the 120 still available. It mimics 120/240 service. If that's it, I'd imagine that the box is quite heavy.

Tom Raymond Posted December 8, 2015 Report Share Posted December 8, 2015 Very heavy, its bigger on the inside. Quote Link to comment Share on other sites More sharing options...
