Chinese Motors?

Status
Not open for further replies.
Good morning Gents,

In reading some of the other forum topics with in Electrical Calculations/Engineering, I have a questions regarding a Chinese motor. Our GC received and installed a 10T electric chain hoist, with (2) motors(one up motor and one down motor), to lift an interior climbing core system. We have been asked to hook it up. Issue, I looked at the motor name plates and the markings are as such:
  • 220/440V
  • FL: 7.8A
  • PF.F:86%
  • Freq: 50/60
  • 3 PH

What it does not have, required by 430.7, is:
  • Most of required information of Usual Motor Applications

I could not find a UL listing but the GC is telling me that it has a "CE" listing (European). My question, do you hook it up? Even though it is a temporary installation, we still abide by the all mighty NEC. To go even further, being that I am in Washington state, our Washington Administrative Code 296-46B-430 states the following:

"Markings on motors and multimotor equipment"
Except as required by the NEC, there is no requirement for motors to be identified for use or listed/field evaluated by a laboratory. All motors must be manufactured according to the National Electrical Manufacturer's Association (NEMA) standards for motors except motors that:
  1. Are a component part of equipment listed or field evaluated by a laboratory: or
  2. Are a component part of industrial utilization equipment approved by the department per WAC 26-46B-903

The (2) motors are connected to a lifting apparatus, with one control box to operate both motors.


Your thoughts are always held in high regard.

Thanks,

UL listing of motors is not required by the NEC in general, NRTL listing of some specific EQUIPMENT that might include motors is required in places. I'm not sure about what you are describing, but probably not. If it is portable equipment, even less likely.

That said, your company's insurance policy may have something to say about it, but that would not affect whether you would or would not hook it up safely.

Side note:CE is just a self-certification designation that the equipment meets certain IEC (translate; European) standards, but it is not a third party NRTL listing, it means doodely squat in North America.

If your ‘made-in-China’ motor happens to be installed in a Classified Area (i.e. Class I, hazardous location), it only has to be"identified" for the location; it does not require ‘Listing’ or labeling as long as it conforms to NEC 501.125(B).

L&I (washington electrical ahj) likely won't approve this if its more than a motor, is there a control panel with it?
CE by the way, means nothing (as regards to listing).

Also our electrical laws, require all materials, devices, appliances, and equipment used in such installations shall be of a type conforming to applicable standards or be as indicated by a electrical product testing laboratory. 19.28.010 (1), this was first introduced over 80 years ago in 1935
 
Here are pictures of the motor name plates as well as the control box that operates both motors (not sure why I thought these were Chinese motors). If you can picture in your head that there are (2) identical motors mounted opposite each other on the same steel lifting assembly. Both motors operate together as up and down functions. It looks like the "CE" listing is for the chain hoist itself and not the whole assembly.

Thanks gents!!!!

Œ marking is a little more complex than that, along the lines of UL meaning doodly squat over here.

CE marking should set alarm bell ringing, equipment is marketed as China Export
