Hi,

No big deal in putting one on, but was just
curious what the code requirements are, as I'm used to working with metal
gang boxes
rather than the plastic ones.

For a plastic box:

Regarding the bare ground wires that one twists together in the box, is it
required to still put a wire nut on them, even though they are twisted very
well together ?

Thanks,
B.



There is no exception in the code that excludes the Equipment Grounding
Conductors (EGCs) from the requirements of 110.14. So, yes you do have
to use a crimp sleeve, wire nut, or other listed means to join the EGCs
together.

110.14 Electrical Connections.
(B) Splices. Conductors shall be spliced or joined with splicing devices
identified for the use or by brazing, welding, or soldering with a
fusible metal or alloy.
