Should surge protectors be installed in the distribution box
According to the requirements of GB51348, not only a surge protector should be installed in the distribution box, but also a backup protector should be installed in front of the surge protector. Installing a Surge Protection Device (SPD) inside the distribution board is widely recognized by engineers and electrical standards as one of the most effective ways to protect the entire electrical installation from these destructive events. Connecting cables that are too long often lead to problems.

Wiring of the three-phase motor distribution box
This guide covers every common three-phase motor configuration — 3-lead, 6-lead, 9-lead, and 12-lead — with wiring diagrams, voltage explanations, wire sizing tables, and the real-world tips that come from over 50 years of helping people run three-phase equipment. Knowing how to wire a 3-phase motor correctly depends on two things: reading the nameplate and understanding what Star and Delta configurations mean. Get it wrong, and you risk burned windings, tripped breakers, or worse — a safety hazard. If markings are missing, use a digital multimeter set to resistance mode to find the three pairs with equal ohmic values–each pair. The wiring diagram for a 3-phase motor shows how the motor's three windings are connected to the power supply and control circuits. Each terminal should correspond to one of the phases.
