MPdesign Posted April 17, 2014 Report Share Posted April 17, 2014 Hey guys, I have an apartment complex with Stab-lok panels. They are fed overhead. I could not find a main for any panel & the maintenance guy there for 3 years did not know of one. Any ideas? I have never seen a unit without a main. By the way, they also have 3 prong receptacles with only 2 wires going to them. AND... what does the knob in the middle of the panel do?

John Kogel Posted April 17, 2014 Report Share Posted April 17, 2014 I believe the knob can be turned to bring the breakers out tight against the deadfront. Never seen one like that, but a lot of them had spring-loaded panel boards. The main breakers are probably in a locked vault with the meters. Did you find a meter?

Mike Lamb Posted April 17, 2014 Report Share Posted April 17, 2014 If it's not with the meter then there is likely no disconnect. I only see six throws. Is a main disconnect needed? Whoops. Now I see 7. Quote Link to comment Share on other sites More sharing options...
Douglas Hansen Posted April 17, 2014 Report Share Posted April 17, 2014 I once saw a small commercial building with four suites, each of which had stablok panels of the same age as yours, and which had no service disconnects at all. There were meters on the exterior, with no mains, and I was able to trace it and confirm that there was nothing between the meters and the individual panels. Bizarre - sounds like you found the same thing. Quote Link to comment Share on other sites More sharing options...
Jim Port Posted April 17, 2014 Report Share Posted April 17, 2014 Looks like it falls under the 6 throws or less rule. Quote Link to comment Share on other sites More sharing options...
Nolan Kienitz Posted April 17, 2014 Report Share Posted April 17, 2014 7 breakers by my count as Mike L. noted above. Look at the open cover JPG. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted April 17, 2014 Report Share Posted April 17, 2014 Two weeks ago I was looking at investment properties. I toured 12 apartments in 5 buildings. Only one of them had a proper disconnect, this FPE that has been in service since 1915. Click to Enlarge 44.42 KB Quote Link to comment Share on other sites More sharing options...
Jack Davenport Posted April 17, 2014 Report Share Posted April 17, 2014 there are 7 breakers - 6 on top and 1 on bottom There's most likely a meter room somewhere that has meter stacks with the mains in it. the bottom breakers in that panel violates 240.81 in the NEC. From the 2011 NEC article 240.81 Circuit breakers shall clearly indicate whether they are in the open "off" or closed "on" position. Where circuit breakers are operated vertically rather than rotationally or horizontally , the "up" position of the handle shall be the "on" position.

Bill Kibbel Posted April 18, 2014 Report Share Posted April 18, 2014 the bottom breakers in that panel violates 240.81 in the NEC.

Jack, was that in the NEC when the panels were installed? Is everything now a "violation" because of new versions of codes? Quote Link to comment Share on other sites More sharing options...

Well - Not sure when those unit panels were installed, BUT i did look at the 1978 NEC and it was in there then. Quote Link to comment Share on other sites More sharing options...
