Need Help!- On Turning On A Lathe

[Brenck]

Hi everyone,

Recently I bought a chinese lathe, and when I tried to turn it on all the energy from the garage went off...

I live in a appartament and each people that livs in the building have like a little deposit room in the garage, I made mine to be a workshop... And this lathe i putted it there, its a like a medium lathe it got a 1 1/2 HP power ( 1100 watts ) and its wired on 110v, because thats what i get there... When I tried to turn it on there as soon as I turned all the lights from the garage went off and i had to go to the eletrical board or control thing and swith the key on again.... Basically I cant turn it on there for some reason....

I cant understand why it didnt turn on because I worked there before with a 400W drill press and a 600W grinder at the same time and I didnt have any problem like that...

Any Ideas on how to make my 1200 pound paper weight ( for now ) work?

Does anyone know what I need to do and I dunno if i have to change the wire thickness from my deposit room to the eletrical board... Or something like that...

Thanks

This may be a silly question but does the lathe require 3 phase 200vac to run? Most lathes I know reuire this to power up but I do not know what you are hooking in. You may want to ge an electrician in there.

Brenck,
Checking the full load rating on a 1 1/2 HP motor shows a 20.4 amp rating at 110V. This is the full load rating and realize the in-rush current for starting can be several times that. Some sources will say up to 6 times!

You need to check the rating on the breaker/fuse you have to see what it is. It may well be 16 amp??? On the other hand, if it is 20 amp, you need every bit it can supply (and maybe more for a short time) to get the motor running. Turn off anything else you may have running to get it started.
IF, you have to get a new line run, see if you can get a 220 plug put in and run the lathe on 220 as that will cut the amps in half.

Obviously the first thing is to make sure everything is free, you may want to disconnect the drive belts to make sure.
Was it running at the previous location and on the same power? 110v 1 ph?
Chinese motors have a notoriously high failure rate, if all the above is confirmed, I would remove the motor and test it on the bench or at another location, If you have the same 15amp outlets as N.A. then it should be able to handle it.
No Bubba's right, I overlooked the 1 1/2 hp, it will be too high for a normal outlet and 15amp breaker.

I just pulled up a manual file from an Enco lathe with a 1 1/2HP motor and they recommend a 30 amp breaker on the 115V line (15 on 220). At best, he probably has a 20 amp line in there.

[Brenck]

The motor on the lathe is 110v 1 phase, i orded like that due to the fact that there is only one plug on the little room and its 110v, on the lathe is specified that its 110v to...

Well i tought that if it was 1100watts... it was supose to be 10amps... 110 x 10 = 1100...

Thanks a lot bubba, i will try to change the breaker for a 30 amp one. What about the wiring from the plug to the breaker? Do you have any info on what gauge they should be? AWG 14?

[Bubba]

Off the top of my head, 10 ga copper wire would be used for a 30 amp circuit if the run if reasonably short.

[Brenck]

Oh ok thanks man, i will make the modifications and see if everything works

[MrWild]

BAD iDEA!

All the other lines will still be wired in 12 - 14 gauge. If a problem happens on any of the other lines, you will have a fire. If there is room for another circuit breaker in the panel, you really should install a separate 30 amp breaker and run a line directly to your lathe,.

[Brenck]

Ohh well taught, i will ask the electrician to install a new one, there is still like 3 rooms in the panel.

I just checked on the motor in the back, it says 17amps... And its 110V, just to make sure of what I already knew...

Hi All--

If you are having the Breaker Turn Off Fast ( Trip)
your load is To High --Most Likely --

Do Not Just Replace Lower Amp Breaker with Higher Amp Breaker
You will start a Fire at Some Point in time--

You live in Apartments --
You dont want to hurt your neighbors --

Find someone that knows what they are doing to
add a Second line for you --

Parts will cost you about $35 depending how much
wire you need --
Run 220 volt to room if you can --

But --
If you live in a Old building the Breaker- MAY -
need to be replaced with a new one --
same amp size Only -

Sometimes turning On and Off the Breaker switch
several times can get the Breaker to stay on --

Turn off Breaker and Tighten All connections --

Ohh thanks man, I forgot to post here, I turned that on already, there is like 6 months that I got it running, no problems and I measured the temperature at all the way of the wire and its holding up good no heating at all.

Thanks for everyone that helped
