Are there any usage charts to tell you when or how to use expansion joints in EMT? The NEC has one for PVC, but what do you refer to for EMT?

The part # is TX-125 for 1-1/4", and it would be TX-150 for 1-1/2". It is the same as the OZ-Gedney AX expansion coupling for rigid conduit, but uses a rigid nipple and EMT connectors to adapt to EMT. The assembly is UL listed. -Hans _____ From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Erika Weliczko Sent: Wednesday, March 30, 2011 5:54 PM To: 'RE-wrenches' Subject: Re: [RE-wrenches] Expansion joints I recently used a Hubbell Killark product for rigid/IMC and was not happy with how the threads of the coupling engaged in factory conduit threads. Crousehinds XJG-EMT series is intended for EMT. And is described as being used indoors or outdoors. The EMT couplings mostly seem to be compression.

I have also heard that many EJs are designed for rigid conduit (RMC) and may not be directly applicable to EMT. - Peter Peter T.
