ScenicCabinRentalsRRG Posted January 28, 2019 Report Share Posted January 28, 2019 Hey all, I am wiring up a Circ Pump that is 240VAC but only has a 3-wire cord (white-black-green) and is my 1st time encountering a 240VAC component that does not have a 4 wire cord. Do I need to label the plug that it is 240 Volt, or label the white wire as a hot so I do not confuse the next guy behind me? Is is more common practice among techs to just use a 4-wire cord and leave the white leg coiled at the termination point in the pump? I know how the pin outs need to be in the amp plug, and have set the control board for a 240V circ pump. My question is specifically on what common practice is for identifying to the next guy behind me that this is not a 115VAC powered component beyond the marking on the motor itself. Bonus Question: What tool do I need to De-pin the amp plugs? They are TE Connectivity Mate-N-Lok connectors and calls for extraction tool P/N: 318851-1 and is $55 dollars shipped. I know there has to be a less pricey extractor for this connector as they are everywhere. As always, any help is much appreciated Thanks.

Generally, circuit board wiring diagrams will designate that the circuit board is pinned for either a 1 speed or 2 speed pump. I don't think it is necessary for you to mark anything because 3 wire cords are standard for 1 speed pumps across the board.
