Atlas lift wiring.

[3rdgendslmech]

Just about finished with the installation of my lift.
The motor was shipped with what looked like 12 gauge SOOW cord through a connector, ground to the body of the motor. 2 hots to the contractor switch.
My install plan was to run 10/2 armored cable to a 240V 30 Amp switch, the from that switch run 10/3 sjoow or slow cable into the same place as the manufacturer.
That way in the even something goes wrong I don't have to run across the shop to the breaker panel.
Looking at the contactor, I have to use braided wire because of the jumper wires.

A whip with liq titell is better, forget what it's called at the moment. 12 may be suffecient.

Make sure the switch is rated for the same or higher HP as the lift motor.

Good call Wylie! Just looked up the specs the motor is 2.2KW which is 3hp. The switch is only rated for 2HP according to Legrand.

Shy of going through Amazon to get a simple on off switch, could I just mount a 30 amp disconnect?

You need to go by the nameplate HP rating if its on there. Otherwise, use the nameplate FLA rating then correspond it to the FLC chart in the NEC- 430.248

as for a switch, you could always use one of these. I doubt the motor is more than 5HP

Just as a matter of convenience. If you already have a roll of 12 AC can use that. I have never seen one of these need a wire bigger than a 12 and as long as there is not a 30 recept on it legal.

 

[3rdgendslmech]

This is the tag that's on the motor....I take it 2.2Kw is converted to 2.9 HP

 

[wyliesdiesels]

Gosh i hate it when they do that.

14.5a FLA is about 3HP...

Technically I don't think a cord is spozed to be used, not that it isnt done all the time. AC whip is ideal.

This is how I wired my Atlas.

 

[sberry]

Yes, piped all the way to mine.

 

[wyliesdiesels]

This is how I wired my Atlas.

Whats the HP rating on the motor?

That switch is rated for max 2HP.

His is North of 14, my Mohawk is 13 something. I have the breaker local but I have a box to put a switch in I couldn't find at the moment. Its on my to do list, I found one.
But, now I see it in a thread and I walked out and looked, 2.5 hp on the motor. Hmmm, the switch I had doesn't even have HP rating. Its not the worlds greatest sin to use here, should never have to switch under load.
Having said all that I have a 10/30 to a Jbox where it splits with 10 to go to a welder recept and a 12 to a switch/jbox for the hyd unit. I think the factory cord supplied about 18 inches is 14. The dealer supplied a plug and recept and insisted it have one but that would have meant a cord as they had a cord recept, 3 phase they must have used for all their installs.
Before anyone gets shook some of the details were finished after the pic.

We have that code for a reason.

Do we want to wire things to code or just throw it out the window and jury-rig it because were too lazy or cheap to wire it the right way? Or because we think nothing will ever happen?

 

[sberry]

I didn't put it in. I agree its there for a reason but its not the biggest booger I ever see. Neither is the modern 5 hp comp on the 10/30 cable circuit. Millons of them wired wrong and never heard of an incident with 1. Have seen 7.5 wired 12 cable work for 20 yrs. Those often wired by the maintenance "electrician" from work.
I would say number 1 is 30 fuses on overloaded generals, saw one the other day with 14. I see old houses with 3/4 of it chained on to an original circuit. Saw one recent had all kind of new wire for circuit never used, didn't shed any load from the original that went all over and had multiple taps from additions.

 

[sberry]

No box connectors, cover removed and mis wire nutted on, wrong polarity, switches breaking common. Saw one recent had a single thhn run across the place in the attic to complete some 3 way rig job.

There can be different perspective, some guys work where money is never an object and the customer has 100's hanging out of their pockets to have someone fiddle with it to no end. Had one I managed to take off a 30, get on 20 gfci to a garage they had 14 wired. I put in a disconnect switch, 12 to a recept, old broke 2 wire job and I did hook the 14 for the lights back on. There was a switch for them. Its not too lazy but they already didn't want to cough up some more, there is a limit and its a calculated risk.

Mine isn't even used daily, if it was a new quick lube with full paying customer I would consider the additional risk, my own with the breaker a few ft away in plain sight,,, not such a big deal.

 

[sberry]

I saw one a while back, guy told the customer he was a licensed union spark. NM buried, they did manage to ocpd it at 20 thru one side of a dp breaker to a 2 pole breaker box, I don't recall all the details but a mess wired thru 1 breaker a 30 somehow, floating panel and a mash of romex and piece or 2 of ac to 2 gfci outlets. No box connectors,,, this ois a showerhouse, laundry, lights, lots of water.
I did manage to route the incoming wire thru a breaker to provide a disconnect, ground the box, use a couple connectors. I would gladly have dug a new ditch, ran a new wire and a couple other things it really should have had if they pulled out some hundreds and shoved them in my pocket. As it was I took the big boogers out best I could on a service call.

 

[sberry]

Aint no one here a lazy fuk, I do a lot over to get a lot of it right. Sometimes its in stages. Buy a lot of new materials where it comes out of my pocket.

 

[sberry]

There are lots we should watch out for,,, appliance dealers for one and some handyman types still cant manage to install a dryer cord correctly. On occasion homeowner types too,,, totally disregard and have no comprehension of safety and don't seem to be concerned in the least, somehow insurance companies manage to write on them. Home inspectors too, cannot trust a word they say. I had an owner complaining about one and I told him,,, even a blind man can see this, should have told you the inspector was fos, all taped to an old kt, no cover on the fuse box with wire hanging everywhere running in the box so the cover couldn't be put on if they wanted to. Outright a mess, this is a guy ok loans for bank and insurance. Not just a minor switch,,, whole place, not one legal circuit in it.
