Cable Gland Reducer

05/14/2013 4:59 AM

Is there any alternate economical solution to avoid gland redcuer for motor terminal box.

Actually the hole for cable in motor terminal box is large as compared to cable gland creating the requirement of gland reducer & i want to resolve this issue without spending money due to limited budget. The area is IIB Zone 2 T6.

Thanks in advance

One of the options is to install larger cable and a larger gland to fit both the cable and the hole in the terminal box.

Are these EEx d glands or is the terminal box EEx e to an EEx d motor?

  • If it is the latter, then a hazardous-area-certified gland or gland reducer is not required.
  • If it is the former, both the gland and any reducer used must also be EEx d, properly fitted in accordance with the suppliers' documentation.

A hazardous area rated termination is required, whether it requires EExd or EExe is determined by the installation equipment certification and the area installation classification standard.

Correct. The forum has been told some of this already, though the nature of the junction box on the motor is still open at this juncture.

You cannot in this case given the information provided.

The simplest and cheapest solution is an Ex rated gland reducer.

Your other options are changing the cable to a larger one that will fit the required motor gland entry size or sourcing another Ex rated cable gland that may possibly support a smaller cable you are trying to fit.

Three potentially viable options for a hazardous area installation, pick one that meets your needs.

What is the cost of not resolving it?

Use of correct reducer is the most economical and appropriate solution here. The cost of reducer is very small compared to the total cost of motor, cable, starter, gland etc.
