Topic tags/keywords: wiring electrical

I’m asking for assistance, this time on a detailed electrical question…

I’ve attached two photos – I’ll try to attach two – of a Leeson motor, fresh from its box. Immediately above is of the electrical wires, as they come tumbling out of the electrical box – P1, T5, T4/T8 (joined), and T1 are bare-ended; the top is the faceplate schematic of how the motor is to be wired for CCW rotation (P1 to Line – I assume this means a 10/3 Hot lead; T1/T8 (joined) – I assume these should be wire-nutted, and kept internal; T4/T5 (joined) to Line – I assume this goes to the 2nd 10/3 Hot). I’m Lost – evidently, the day electrical experts paid attention, I was throwing rocks in the school yard – as I’ve researched this, I have developed an abiding respect for electricians…

I’ve annotated each picture – I hope this can be read. Assuming that 1) I’m wiring directly back to the Electrical Panel (I’ll wire it to a switch, close at-hand, then to the Panel); and, 2) run the motor Counter Clockwise. Question – Wire Nut the following:
P1 to a 10/3 hot;
T5 & T4 (joined) to a 10/3 hot;
T1 & T8 (joined) to nothing (will remain wire-nutted together inside the motor junction box).

Thanks for your consideration.

You are correct, sometimers disease hits us all, sometime I remember and sometimes I don’t. I’ll throw this in for you https://www.electricmotorsite.com/pdf/120824diagram.pdf

You are correct, sometimes a detail wiring schematic is available, what you have is far superior to what is available on much older motors, especially those which have been in service for some time and the info plate is barely legible. Now figuring those out is real fun!

Thanks for the prompt and considered responses. The motor is to a Clearvue Cyclone system, and not a stock Leeson item, so their website doesn’t list a schematic – Dustmagnet, interestingly, I pulled the same schematic from Leeson (not that I understood it…), however, I got to it using a different Product # and Catalogue #, and was not comfortable that I had found a correct diagram…

Without the faceplate, I don’t know what you would do.

Thanks, again.
