Is it possible to connect two wires to one machine?

Good afternoon! Is it possible to clamp two wires of the same cross section into the terminal of the machine? The shield does not have enough space for installing an additional machine, and an additional outlet is very necessary. I want to connect both sockets (existing and future) through one circuit breaker (abb sh201L). Or is it better to make a junction box and connect 2 sockets to one machine through it? Thank.
