Default Re: All Breakers on left side of bus

Steven,

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.

Any good electrician can in a very few minutes get all legs that are used constantly close to Balance
.
Of course intermittent loads are different.

I know some GOOD electricians Roy and they don't have a clue on how to properly BALANCE a 3 phase panel.

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 .
