Re: Clone 320.40 into 330
inside mc cable the conductors are wrapped in a plastic jacket. sort of a pre-anti-short bushing
when properly installed in a prebushed compatible connector (ex. SpeedLock or Arlington L15A)the "plastic wrapping" acts as the anti-short bushing. the plastic wrapping should extend throught the insulated throat of the connector.
the connectors are ul listed for use without the anti-short bushings.
what i see all too often is mc cable that has been cut in the field with either "wire cutters" or "tin snips" and the plastic jacket cut or folded back before being placed in the connector. RED TAG for that !!!!
use a Roto-Split to cut your mc cable and bring the plastic wrap through the insulated throat of the connector and you have a code compliant and ul listed install.
that being said - i always use anti-short bushings with mc too.
inside ac cable is twisted/braded paper leaving conductors exposed to contact with the jacket.If someone could explain to me how, by whatever mechanism, MC has some sort of immunity to damage from rough armor ends that AC somehow doesn't have, then I'll become a believer that everything is fine the way it is
