What is this box & terminals called in the USA?

[TheWildDingo]

Dumb question, but I was watching a YouTube video of an English gent extending some wires on his sailboat. He used this "junction box" (see pix). Is that what they are called in the USA? What are the terminals inside the box called?

Thanks!

A terminal block. If the terminals are connected electrically in pairs like this it is a terminal block. If there are multiple terminals connected together it would be a busbar.

Eurostyle “touchproof” terminal blocks. Inside a eurostyle “splashproof” junction box.

I don't know the standards but I wouldn't use that style terminal block with stranded wire in a high vibration environment.

I've seen people recommend using ferrules for that purpose but if you're going to use ferrules, why not just use a proper terminal block with ring terminals?

Cinch-Jones style terminals are not touch safe in a line voltage use case. And safety guards are not common for them.

Yes, you should definitely cover them. I didn't mean to imply that the box would no longer be needed.

They make crimp on end caps for the stranded wires, which you can then in turn put into the terminal blocks.

Yeah, I said that...

Even more than that. Anything that can be touched in a working electrical box needs to be shock safe. This protects workers adding or modifying or replacing parts on an operating system. EN60601-10. Not a factor for less than around 48V. +/- wet/dry etc etc

Thus the euro style terminals, din terminals, CB, fuse holders etc Much different than NAmerica norms.

The insides of your electrical boxes are safer than our outlets.

Not sure on that, the picture shows European 240v AC cables with blue/brown/green connected to red/black. Except the Line (positive) goes to black and the neutral blue goes to red (positive or line) on the left hand side and a different arrangement on the right. That will be fun for the next owner trying figure out what is going on. It might be that the owner is using AC cable to run DC voltages, but still confusing.

The choc blocks one white and one black, have a plate that the screw presses down onto the cable and a second lower plate to make a firm contact and good hold.

At least I kept the colour scheme consistent. Wiring tidied up once I was sure the RCBO (GFGI) and analogue kWh counter worked properly, after being mystified by the Chinese instructions in a font size I struggled to read even with glasses
