Both sides of the mounting plate 8 are clamped in the slide grooves 4 and slide along the slide grooves 4. A power connection box 9 and a circuit breaker 13 are installed on the mounting plate 8. A power supply box 5 and a main incoming line box 6 are installed on the back of the electrical cabinet. The power supply box 5 is electrically connected to the power connection box 9.

[0023] When wiring is required, first pull out the mounting plate 8 from the electrical cabinet 1, and perform wiring on the mounting plate 8. When the loads to be installed are all connected to the circuit breaker 13, insert the mounting plate 8 into the electrical cabinet 1. At this time, the power connection box 9 is connected to the power supply box 5 and the main incoming line box 6 and power is turned on. The wiring method outside the cabinet not only reduces the safety risk in the wiring process, but also can reasonably arrange the number of plug-ins of the mounting plate according to the size of the connected load, thereby reasonably planning the wiring space.

[0024] The preferred solution is Figure 2 As shown, the incoming end of the main incoming box 6 is connected to the power bus 7, and the outgoing end of the main incoming box 6 is connected to the power supply box 5 through the power supply line 19, and the multiple power supply boxes 5 are connected in parallel.

[0025] The preferred solution is Figure 3 As shown, a power supply bus bar 10 is arranged in parallel on the mounting plate 8, and both ends of the power supply bus bar 10 are vertically connected to the mounting plate 8 through insulators 11 to ensure the insulation between the power supply bus bar 10 and the mounting plate 8, and the power supply bus bar 10 is connected to the outlet end of the power connection box 9 through the power supply bus bar 12;
