- Scope
- This part of GB 14048 specifies the requirements for protective conductor terminal blocks mainly used for industrial threaded or non-threaded clamping parts. The terminal block with PE protection function is not larger than 120 mm2 (250 kcmil ), terminal blocks with PEN protection greater than or equal to 10 mm2 (AWG 8). Protective conductor terminal blocks are used for electrical and mechanical connection between copper conductors and mounting brackets. This section applies to AC circuits with a rated voltage not exceeding 1 000 V, frequency up to 1 000 Hz and DC circuits not exceeding 1 500 V with a connection cross-sectional area of 0.2 mm2~120 mm2 ( AWG 24 kcmil~250 kcmil) protective conductor terminal block for prefabricated or non-prefabricated round copper conductors, the protective conductor terminal block and the terminal block specified in GB/T 14048.7-2016 are usually used together. The following products can use this part as a guide: --Protective conductor terminal blocks that require special devices on the wires, such as quick-connect terminals or wrap-around connections; --Pierce the insulation by means of edges or points Protective conductor terminal blocks in direct contact with conductors, such as insulation transfer connections, etc. When referring to GB 14048.1-2012, this part uses the term "clamping piece" instead of "terminal".
