Greenfield (FMC) conduit with unshielded ground

[kopeck]

Hi,

I need to make a small change in the wiring for my boiler and I was wonder if it's OK to run an unshielded ground (ie bare copper) through Greenfield flexible conduit?

I really don't see why it would be a problem but though I would ask first.

Thanks,

K

Kopeck,

Does this ground do anything othere than bond? I am pretty sure that thhe grounding conductor can be bare.

ANy more details would help, though.

You can run a bare ground wire inside of greenfield with no
problem it is much better than using the flexible metal conduit
as your ground. Green insulated is preferred but not
nessacery.
The grounding is the most important wire in an electric circuit
when there is a problem.
Did a service call years ago where a 2 pole 30 amp fuse
disconnect was added to a old split phase fuse box.
The Romex connector was tighted all the way down on the
cable and the ground wire was cut off and not connected,
After 15 years or so the red conductor became knicked and
energized the entire fuse box because of no pathway to
ground to short out.
Note this was tapped straight from the main lugs with no
overload protection untill you got out to the transformer outside
on the pole. 100amp 120/240 volt service.
Customer got a real bad shock from this condition and it did
short out when the fuse box door cover was opened and made
contact with the fused disconnect this could of killed
somebody very easily
Grounds are very important
