Hi all,

When "splitting" DB's, is it necessary to have two completely separate boards?

I have more than enough space on my existing board to split the essential / non-essential loads and add new breakers, by-pass switch, etc.  I'll probably add a small board alongside the inverter which is little way off.

Thanks

With the correct labeling and separation you can do everything in 1 Db. Most prefer 2

Thanks, that what I was hoping to hear - house lay-out makes this preferable.  I'll have to get some help with the labeling, but it won't be worse than what I have at the moment.

Just want to double check this. Not sure about what SANS says, but should each row in a DB have not have a master isolator? My understanding is it is fine splitting between rows, but not within a row. I would add a surface mount 2 or 3 row DB board on top of existing cavity. Can someone please correct me if this is wrong.
