The big difference in the electric terminology and installation regulations and practice in each country!

This is a "switched fused spur":

That's a switched fused connection unit, used for connecting a spur to.

Do y’all not have panels with all your overcurrent and short circuit and run your wires the the devices

is that a fuse beside a switch. Remember I’m in the US and trying to learn y’alls way of doing things

Yes, but as I explained in post #16, the FCU is a handy way of locally creating a small circuit from a large one, bearing in mind that our outlet circuits are often protected at 32A in the DB (panel).

we do. we call them Distribution Boards. domestics are commonly referred to as Consumer Units.

Thanks for the knowledge and help

We use breakers as our overcurrent protection not fuses

We use whatever is best suited to the application.
Generally MCB's (miniature circuit breakers) for small final circuits and MCCBs (moulded case circuit breakers) or fuses for distribution circuits or large final circuits.
Installing two mcbs in series can have discrimination issues, so generally we don't use mcbs for distribution circuits.

The choice of protective device, whether its fuse or circuit breaker will depend on things such as the type of load, the prospective fault current, discrimination.

I was trying to help the OP understand the commonly used terms as described in post #14.

Now, now Andy78, that's a tad pedantic of you! LOL!
Plus, you ended your sentence with an unnecessary preposition. If we are trying to assist our American friend with the correct terminology for our superior electrical items, we should be careful not to let him think our grammar is inferior...
