ECN Forum Forums General Topics of the Trade General Discussion Area Motor wiring connections types

Hello.,

Right now what I am doing is get some info get up to date due some of new items did show up but let me start the connection number/ colours here all the connections are based on single phase motor typically used in North America area but I will add IEC version little later once I get confirmed configuration.



1-Blue
2-White
3-Orange
4-Yellow
5-Black
6-NCA ( No Colour Assigned )
7-NCA
8-Red

P1-Brown
P2-NCA { the P1 and P2 is for overload thermal switch if the motor have it. }

If you have any more updated colour code please post it here so I can get this info up to date for other peoples to figure it out

Merci,Marc

( So once everything is correct I will transfer this to the tech part )

I have the same conversion Marc. Nema standards MG 1-2.41. I am certain you are still correct.

Thanks JV., that what I thought so but the MG1-2.41 specifces are pretty much kinda outdated and need to bring up to date I know it was the same for last 20 something years and it should be updated somehow.

Merci,Marc

I don't think NEMA will ever change the wire designations. Personally I hope they do not change them. The motor manufacturers still follow this chart and if there are any deviations the wiring diagrams on the nameplates put to rest any confusion.
