Mark P Posted April 15, 2012 Report Share Posted April 15, 2012 I am just wanting to confirm that this panel (GE PowerMark Gold - TM 2010) does not permit the use of tandum breakers and it is in fact overfull.

Marc Posted April 15, 2012 Report Share Posted April 15, 2012 Did you mean Tandem or Duplex? Marc Quote Link to comment Share on other sites More sharing options...
Mark P Posted April 15, 2012 Author Report Share Posted April 15, 2012 UMM - is there a difference? Quote Link to comment Share on other sites More sharing options...
Mike Lamb Posted April 15, 2012 Report Share Posted April 15, 2012 http://www.ashireporter.org/articles/ar ... px?id=2047 You are right. Tandems should not be used in this panel. Quote Link to comment Share on other sites More sharing options...
Marc Posted April 15, 2012 Report Share Posted April 15, 2012 I think of tandem as one 2-pole breaker and duplex as 2 single-pole breakers in one slot. Marc Quote Link to comment Share on other sites More sharing options...

Inspectorjoe Posted April 15, 2012 Report Share Posted April 15, 2012 "20 poles maximum" is printed on the label. It's too bad all panelboards don't contain that info. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted April 15, 2012 Report Share Posted April 15, 2012 "20 poles maximum" is printed on the label. It's too bad all panelboards don't contain that info. I'd like to see the transform that produces 20 poles of power. Why didn't they just say "20 breakers maximum." Quote Link to comment Share on other sites More sharing options...
Richard Moore Posted April 15, 2012 Report Share Posted April 15, 2012 Why didn't they just say "20 breakers maximum." Well, then you would have some arguing that the 240 vac breaker for the range is just a single breaker. Johnny Homeowner buys and installs a "single" breaker, no matter how many poles it might have. The number of poles may still be a bit confusing, but perhaps it will at least get Bubba to ask questions. Slight thread drift. I just discovered that the 42 circuit/pole max for panels has been largely removed with the 2008 NEC. 408.35 is no longer there. See http://static.schneider-electric.us/doc ...

hausdok Posted April 15, 2012 Report Share Posted April 15, 2012 It would be interesting to have the opp to pop one of those breakers to see if the bus has a rejection feature and if so whether the breaker had been modified; and if there is a rejection feature and the breaker wasn't modified, find out what type breaker is being used.

Charlie R Posted April 15, 2012 Report Share Posted April 15, 2012 You are correct, no tandems allowed. Panel is labeled 20 pole max (and it is also indicated by the model number), I count 26 Quote Link to comment Share on other sites More sharing options...

I'd like to see the transform that produces 20 poles of power. Why didn't they just say "20 breakers maximum." Because some breakers might be 2 pole breakers that take up the space of 2 poles. I call a 2 pole breaker a 'breaker', not 2 breakers. Marc Quote Link to comment Share on other sites More sharing options...

The number of poles may still be a bit confusing, but perhaps it will at least get Bubba to ask questions. But the words "20 poles maximum" do not restrict what was done here. Each tandem breaker still has a single connection to a single pole. The installation in the pictures still has only 20 "poles" (to use their bizarre term for each position on the bus bar).

The terminology is both wrong (because these panels only have two "poles") and confusing. Quote Link to comment Share on other sites More sharing options...

Don't newer panels specify 'maximum circuits' instead of 'maximum poles'? Marc Quote Link to comment Share on other sites More sharing options...
Norcal Posted April 16, 2012 Report Share Posted April 16, 2012 The twin breakers installed in the GE, Goverment Electric panel are not GE, & I doubt they are UL classified to be used in one. GE twin breakers are peculiar to GE & they will not fit a non-GE manufactured panel. Quote Link to comment Share on other sites More sharing options...

Jim Port Posted April 17, 2012 Report Share Posted April 17, 2012 A 2 pole breaker counts as two poles, however if you were to count circuits it would be one. Quote Link to comment Share on other sites More sharing options...
