I can tell you that every (maybe not every but every breaker in common use) domestic circuit breaker sold in the States today uses a screw to hold a solid stranded wire in compression. Typically 14, 12, or 10 gauge solid copper wire. Aluminum wire is no longer used inside houses, but commonly used for street to house connections (its stranded).
Typical wall outlets are 120V with 15 to 20amp breakers. 240V circuits (clothes dryers, ovens, water heaters, heat pumps, large AC units) use 2x 120V legs + and 1 or 2 neutrals.
A 240V breaker looks like this, the wires go under the screws shown
A 120V breaker would be 1/2 the width and only have 1 screw.
Inside the ciruit breaker box is a distribution bar supplying power to the back side of the breaker which then sends it out to the wire/device.
Neutral (ground) bars in a house look very similar to the choc block shown. Just made of tinned copper.
Again a solid copper wire goes under the screw.
Obviously none of these products are remotely suitable for a boat. But they are code approved and in virtually every house here in the States.
