How is your 2 post lift wired?

[bd8134]

I have a Bendpak XPR-10AS which has been installed about 9 years.
My electrician wired the lift with the electrical cable running inside the post.
He used the metal tags that are on the inside of the post in the center.
Tonight I had sparks coming from inside the post when lowering the lift.
Looking inside, with power off, I saw a cut had been made through the insulation exposing the the wires, right where the cable goes through a grommet, to the outside of the post to the motor.
The cable has to make a bend as it goes in the grommet / hole and it forms a slight curve away from the post and that is where there is a slit going vertical.

How is your electrical cable run down to the motor?
Inside the post or external?
How is it secured to the post?

I'm an electrical contractor. I have hooked up several lifts, all outside the columns. I use drill screws into the columns to secure conduit and boxes.

My bx cable goes from a box on the ceiling to the shutoff switch and down the outside of the column to the control box.

all i have used were wired down the outside of the column

On the inside of post?... Doesn't sound like a good idea at all. Just asking for trouble.

Are you sure this guy was an electrician? Doesn't sound like it to me.

external, with MC cable.

I ran my wiring all in EMT from the circuit breaker to a J-box mounted on the ceiling above the post. I then used a strain relief to hold the SO cord from the J-box and ran the SO cord down the outside of the column to a DPST switch and then into the pump unit, leaving some slack between the strain relief and the J-box mounted on the ceiling. I ran it through a double pole single throw switch to allow me a point to kill power without having to go all the way back to the circuit breaker if needs be.

I would not have ran it down the inside of the column but that is just me.

Outside in conduit! I helped a friend install his lift and the instructions had the main wiring outside..BUT, the height limit switch is wired inside. It has several 1/4" pipes about 4 inches long to thread the wire through. Offered to drill the hole and wire it into the conduit that is "right there!!!!" but he was sure it was safe. The experienced paranoid inside of me just cringes.

My Rotary is a bit of both. It depends on the make I would think. Mine has a channel that I ran the wires in. Then I popped them out into ether switch box or plug ins.

The one upper box actually houses two 20 amp fuses as I split the feed to the lift motor and powers the two power cord reels.

Any spark from wiring should have tripped the breaker.

Outside the column's.

I find it hard to believe that an electrician.......a real one........would have wired a lift with a feed on the inside of the column.

I had mine wired up with a plug. That way I can lift and plug a welder in if I need to.
But it is all on the outside. Really can't believe someone would wire it up inside.

And mine is wired with a 3/4" PVC conduit, and it goes from the side wall, under theconcrete flow, up the side of the lift, secured with conduit clamps on welded Unistrut.
