Hello all, I have been a lurker for a few months and have been amazed at the wealth of knowledge shewn and the trouble taken by members to provide answers to what must seem asinine questions. I have taken the plunge to ask such a question myself regarding wiring the three phase motor for my wadkin BZL lathe. I have an IMO EDX 1 HP Idrive inverter. I understand the priciples of three phase but the manual describes elaborate earthing arrangements. not a just a simple daisy chain to the mains earth and shielded cable for thre thee phase legs to the motor . My question is are these steps necessary for commercial elf and safety application or is it sufficint to merely provide adequate sized conductors ie 1.5mm for input phase, neutral and earth and the three legs and earth to the motor. I should be most grateful for any advice that anyone with experience of these drives could give me.
