Yes. How else would they do it, if you can't use two wires under one
screw?

Looks like the sort of thing you'd see in the UK from before WW2. From the
cheapest of makers.

The green screw on the lower left is for the 'Ground' connection. The
silver colored screws on the left side are 'Neutral', and the brass
colored screws on the right side are 'Line'.

I wouldn't have believed that sort of screw connection was still in use.
It's a dreadful way of making a connection. Unless you first crimp on a
suitable terminal.


Then it's a damn good thing you don't do electrical work in the US,
isn't it? What you can't see is that there are grooved slots in the
terminal that grip the wire, when the screw is tightened. 'Crimps' are
illegal, without certified tools with current inspection tags & proper
training. They are used in the few places with aluminum wire, to crip a
copper pigtail onto the aluminum wire, and every part of the process is
tightly controlled. Either hire the right work, or rewire the building
with copper.
