BendPak XPR-10A lift wiring help

I am just about done with the install and have a question about the wiring. This is the diagram supplied in the instructions:



The instructions call for a 240v single phase service via a 25 amp fuse. My issue is that the overhead microswitch is only rated at 15amps and BendPak supplies a 14g 4 wire SJO cord to go from the switch to the motor. Am I reading the diagram correctly? They want one leg of the 240v through the push button microswitch (and then on the motor) and the other leg connected to one of the 14g SJO wires to go up to the switch and then back down a different 14g SJO wire to the motor.

Here is a picture of the switch mounted on the motor:



Also, the wiring diagram shows the N.C. output of the overhead switch going directly to the "power unit" but the picture above shows three wires coming directly off the pushbutton microswitch (ground, L1 and L2 presumably).

Sevensandheights,

You are correct, the reason the switch and wire for the limit switch are rated for 15 amp is because you only have one leg of power running through the switch (1/2 of 30 amp circuit) the green ground wire will ground the conduit or incoming power supply to the Motor, leaving 2 wires at the motor. One will connect to one of the incoming power supply, the second wire from your incoming power supply will connect to the micro switch cord and loop back to the box and connect to the other motor leed. Please call me if you have any questions. Gabe 877-432-6627

Thanks! That makes sense that 1/2 the current draw would be on L1 and the other half on L2.

Not so sure about L1 only drawing 15 amps. This is a 240 volt circuit. What ever current goes through L1 must go through L2 also. It is not L1 to ground and L2 to neutral/ground. I also just put this same lift up and questioned the supplied wire and limit switch. I suspect that the small wire size is based on duty cycle. The motor only runs briefly while raising load. A 30 amp breaker with a continuous (100%) load would require 10 gauge wire.

I used 10 gauge SO cord from breaker (30 amp) to motor and used the wimpy 14 SO cord provided from BendPak to the limit switch and return to motor.

Also had to replace one hydraulic line. The way the cylinders are secured at bottom *****. While standing up columns, one cylinder rotated slightly and was crushed by carriage (wasn't completely down to bottom of column). Lucky that it was the short hose and only cost me an additional 70 bucks...

BendPak installation manual also *****...love the lift though...

Yep, the manual does ****! I wasn't excited about how the provided wire was supposed to run thru the operator side safety cover and simply discarded the cover. Have never regretted it or missed it. IIRC it wouldn't really fit thru the provided grommet anyhow.
