I inspected a panel that had all the breakers on the left side of the bus bar, except for the a/c breaker. I have always seen the panel balanced with breakers on both side of the bus bar. Is this a problem? There are 19 breakers on the one side.
The service should be able to handle this installation, grant it odd but the Ungrounded Conductor will have no problem handling it and the “Grounded” conductor should be sized fine to handle it. Only because if skipped you are looking at like…10 breakers only…lol if on one side.
We are not talking about massive unbalanced issues like in 3 phase systems in this case.
In his case…would not be possible with todays 42 OCPD limitations . Now in 2008 the 42 OCPD limitations will be removed from what I understand and then could be possible issues. But it is the responsibility of the EC to calculate the loads before applying the service…now how many actually do that is always a issue.
lol…Steven I did see a guy one time make a attempt to put EVERYTHING on one leg of the service. I mean he skipped every other one and did the same on each side and only had 20 breakers in the panel but they were all on one leg.
Because in order to do this they were single breakers and limited to 15 and 20 circuits it was not as much a problem...but COULD be I guess if someone did it for a reason and then made an effort to overload the circuits but again you REALLY have to work at it.
I asked him WHY he did that and he said to me in a straight face, " I thought that if you only had 120V loads they all had to be on the same phase"…My reply was…NOPE…
No up here we have in industry a lot of three phase 4 wire system star hook up 120 volt to neutral 208 between any two legs.
We also in industry use a lot of 347/600 volt systems .
The only place 440 volt is used is in the auto plants.
Thats a MAJOR problem in our “Electrical” industry as believe it or not many electricians don’t even know how to properly balance a panel and size a transformer properly in order to keep from overloading a phase, causing premature failure of the transformer.
While this is not a problem in Single Phase in regards to the original question here because of the skipping of busses, in 3 phase a situation like greg stated can be a NASTY beast and can go for years without someone knowing…other than simply replacing transformers and leaving the head office scratching their heads.
That could be because they have not worked enough in Heavy construction .
I had when I first started an electrician license .
That was all that was available as years went on I had to take continuing courses and worked in different fields .
I ended Licensed in all Provinces except Quebec ( Different rules completely and had too speak French )
I had tickets for ,house wiring,Maintenance,Heavy industrial ,and lines man.,
Many think that do one do all and it is not quite that easy.
I choose to have no licenses any more as some liability protection.
Just ask a person who does houses only to hook up a stop start with a jog even with a print some have big troubles .
