ECN Forum Forums Code Related Discussion Canadian Electrical Code Topics Armoured cable and EMT

I work in an industrial plant and we are undergoing renovations in our offices.
A contractor is doing the work and he hired his own electricians to run the conduit for the reno's as I couldn't commit full days to the project as the plant maintenance and equipment breakdowns are my first priority.
All of pipe work for receptacles and switches is 3/4" EMT stubbed up just above what will be the drop ceiling. The part that seems strange to me is they ran BX cable down the pipe and into the device boxes rather than terminating the pipe in a j box and running single conductors.
Does this seem strange to anyone else or am I just outdated? Are there any code violations in regard to doing this? I can't really think of any violations but I have never seen this done before.

You have to use either a box or a BX to EMT conector like this

and skin the metal cladding off AC90.None of the cladding can enter the pipe and there has to be a strain relief and of course anti-short.
I've also seen a bx connector to nipple to EMT box connector used to make the transition.
cheers

Frank,
Thanks for the info and the quick reply.
I am also wondering if you know the code rule that has been violated? I can't seem to pin it down.

For AC90 the inspector will ask you to read rule 12-608 for cable armor continuity and that it be mechanically continuous.
Then rule 12-610 sub-rule (3)for visibility of the bushing...Basicaly they will say it is contrary to these rules so its a defect.Almost the same deal for BX,thats how they rationalize it.
There is no a specific rule but these other rules dictate the installation requirements.

They do not want any of the conductor terminations to take the stress of the cable and should the armor become hot they want to be sure the OCPD clears the fault.
cheers

12-608 Continuity of Armoured Cable.
The armour of cables shall be mechanically and electrically continuous throughout and shall be mechanically and electrically secured to all equipment to which it is attached.

I think this is the rule that nails it down, as it is definitely not mechanically secure to the pipe.
Thanks again Frank
