I remember when fridge doors got wider and we had to knock out a bunch of walls in units to allow more door swing. If the door could not open more than 90 deg then the bottom veggie tray on that side couldn't be opened. Is this explained in school now? Another aspect is placement of the overhead light in dining areas. If there is a door or pass-through opening to the kitchen then the table needs to be moved further from the kitchen wall. If the long wall beside the table has no window then allow for an 18" china cabinet and move the light in that direction. Light boxes are hard to place because of truss positions so many end up with 'swag' chains and hooks to center them over the table. Should notes be added to to blueprints to make electricians aware of possible changes before completion. Thoughts?
