| help: old brook crompton motor wire colours for star |

| Andrew Wildman:
Hi All, I am completing my grinder and I am wiring it for 415v (star). The previous owner had it wired delta for 240v. Having looked at it I think it should be connected: red - terminal a yellow - terminal b blue - terminal c black, white, brown - neutral (I realise I may have to swap the individual wires to terminals a,b or c to get the motor rotating in the correct direction) Can somebody check whether this is usual convention Thank you! :mmr: |

Andrew: Craynerd posted a photo some time ago which tallies exactly with what you're proposing: Phil. |
| Andrew Wildman:
thanks. I have also checked that all the windings are connected to the start point (ie no winding has both end going to neutral) so I think it is ok... let's plug it in and see if the magic smoke stays in :) |

You do know that you do not connect a neutral to the N connection on three phase. This is just a blind bolt to connect the three winding ends together when using the star connection. You can take a neutral FROM here and use one other phase connection to get a single phase feed. |
| Andrew Wildman:
thanks all. Motor working fine! hermetic, yep its just a star point |
