I was told that the outer PVC jacket is removed on a Teck90 cable before installing. Is this true and a common practice?
Utter crap in 99.999% of cases.
In Canada there is probably a couple of million miles of Teck cable installed as is, jacke intact.
The jacket is part of the approval of the cable and with the jacket removed, the cable is no longer approved.
One rare exception.
A Teck cable run in the ceiling spaces of a mall to supply extra power to a new tenant.
Part of the ceiling space was also used as a return air plenum.
The fire code prohibited the installation of plastic material in a return air plenum.
In discussions with inspectors the following factors were considered.
Armoured cable was acceptable in the plenum space.
The inner construction of Teck includes a plastic sheath over the conductors that is not part of an armoured cable and thus Teck may be considered a better build than armoured cable.
The fire code issue was not the cable per se, but the jacket over the cable.
Part of the run did require Teck cable.
The plenum was dry and did not require a cable rated for a wet location.
With agreement from the fire inspector and the electrical inspector, the jacket was stripped from the part of the Teck cable that was located in the plenum space.
