I was just out working on hooking up the electrical connections for my new Polaris booster pump (PB4-60) and am about to lose my mind trying to actually connect the two hot wires in the tight space and on the small nut-and-post at the terminals under the little access cover. Can I put a spade or round terminal connector on my black power wires to connect them to the terminals on the pump? Or do I absolutely have to get my wire attached via the nut and washer on the post at the terminals?
Specifically, there's a post on terminal 1 and terminal 6 (where the two hot wires go - I've got 220v on my equipment pad) with a nut and washer on it, and then a couple of spade connector posts also (one of which is taken up by a wired for the 220v configuration). My problem is this - the posts with the nut and washer are very small (it's a 9mm nut, I think), and it's almost impossible for me to get the power wire routed in that tiny space, around the post, and stay in place while I tighten the nut. The wire just keeps popping out when I get it close to tightening the nut all the way.
How have others attached these power wires? Thanks for any help!
