Scope

This part of GB/T 37751 applies to RCDs with non-threaded terminals and a rated current not exceeding 20 A. These non-threaded terminals are mainly used to connect untreated (see 3.5) copper wires with a cross-sectional area of up to 4 mm2.
This part cannot be used independently. For RCDs with non-threaded terminals, this part should be used in conjunction with the RCD product standard (IEC 61008-1 or IEC 61009-1).
In this part, non-threaded terminals are referred to as terminals, and copper wires are referred to as wires.
