CPC Terminal in plastic surface mounted back boxes...

[junksamiad]

Hoping someone can help me clarify something.

For plastic surface mounted back boxes, why do some have a small metal terminal for connecting the CPC, whereas others don't? Is it just a differemce in quality, or would you generally use the ones with the terminal for sockets, and the ones without the terminal for light switches?

No context with this question, purely curious to the difference and whether there is a logic to it I don't yet understand?

Thanks again.

It’s to stop floating connections. Those without are designed for sockets.

Many light switches do not have a terminal on the face plate for the CPC.
You could either use a back box with a terminal to park the CPC, or as is often the case, just terminate the CPC into a terminal block/choc block.
