    Abstract This paper analyzes the connection modes between 400V-system wires & cables terminal blocks and terminals as well as the those between cables and electrical equipment，and points out two non-applicabilities of the provisions on the connection mode of wires & cables terminal in code of acceptance of construction of electrical installation，namely：whether the cable terminals use connection hardware and tinning；the number of cables connected to a terminal is no more than two.
