ABB motor "peckerhead" hubs

[bradevans6634]

I am wiring some new motors, and the hubs in the peckerhead will not accept my sealtite connectors. Several are 1" and some are 3/4". The connector starts threading but immediately gets tight, before we even get one half a turn. The supplier stated that the motors are "sold globally" and they have never had this complaint. Does anyone have any information regarding a connector with a different thread? Google has failed me so far...

Is it possible that it's metric?

Metric, perhaps?

I believe adapters are available, e.g. http://www.cooperindustries.com/con...ersserviceentrance/reducers_and_adapters.html

The "sold globally" would strongly suggest that.

:happyyes:

Motors are intended for fixed installation only. Unless
otherwise specified, cable entry threads are metric. The IP
class of the cable gland must be at least the same as those
of the terminal boxes.

Thank You

Thank you all. I will find the metric adaptors thanks to you all.

I always got the adapters from McMaster Carr, when I had that issue. They were always in stock, but you have to be sure of the metric size.

In our area the solution is "Bubba, go get me the BIG wrench"

Or The BFW

Cross threading with the BFW is kind of a one-shot deal though.

Officially, you need these:
I'm surprised that the motor supplier didn't offer them or even include them. I used to occasionally use Brook Crompton motors from the UK, they came with them, put inside the peckerhead for you.

The link I posted earlier leads to those. My link is one level up to provide more options... like explosion-proof-rated fittings.
