Merry xmas all,
Hoping to pick your brains a little in regards to kitchen cabinet lighting. I’ve been out of the trade for awhile now and when I was working in the trade it was 99% industrial, so the wiring is no problem but I’m pretty green on the methods. So just a few questions and if you have anything to add in regards of type or brand or dimming etc I would definitely appreciate it.

The cabinet maker gave me some suggestions but I just want to make sure I’m following current methods.
The kitchen is in a U shape more or less and the cabinets will be installed 4” from the ceiling. A crown molding will take up the 4” between the ceiling and the top of the cabinets when all is done.

It was suggested that I install a receptacle controlled by a switch within the 4” space of the ceiling and the top of the cabinets, the lighting transformers would be plugged in there and then I could run low voltage cables from there for the upper and lower cabinet lighting. The cabinet maker would cut me an access hole in the cabinet so the receptacle and transformers were accessible.
Is this typically how it's done?

Personally I thought it may be better to install a receptacle on either side of the “u” rather than run low voltage cable all the way around just to negate voltage drop issues on low voltage conductors but maybe this isn't a concern considering the lights will most likely be L.E.D.'s
Appreciate any thoughts.
