OT home wiring

I know that are a lots of electrical types out there so a quick OT question.

Stopped by a friend's cottage and she asked me if I would add a circuit in her garage so she can have a freezer etc..

It's a really old cottage. The mains are not the basic lay out. The neutral and ground buses are on top of each other and what I found strange is that all of the ground and neutral returns for a given circuit go to the same bus. That is the neutral and ground is wrapped and returned to one bus or the other. No rhyme or reason as far as I can tell. She thinks I'm an electrical genius because she listens to an old pair of two-way speakers I made years ago(hehe). I don't want to break the spell. What's up? What do I do now?

(yaya, I know-call an electrician)

TIA
I remain,
clueless

The grounds and neutrals often go to the same buss. The exception is that when connecting to a subpanel then they are required to be connected to seperate ground and neutral busses.

I would recommend against using ground fault protection on the freezer recepticle. Any sort of motor is easily capable of tripping a gfi (usually during shutdown) and you don't want a refrigerator or freezer losing power because of a false trip. For a test, plug a vacuum cleaner into one of your gfi's and see how often the gfi trips when you switch off the vacuum. Use a (non gfi) single recepticle for the freezer (it can't be a duplex) and provide a seperate gfi protected recepticle for the required general use recepticle.
