The only way to ground your system if you're using plastic boxes is to continue the chain by connecting your ground wires together--just as you would with the hot and nuetral wires--through the entire circuit all the way back to the whole house gound in the circuit breaker panel.
Grounding a plastic box is a little hard as plastic is a nonconductor.be satisfied with grounding to a ground wire.
Yes provided you have a ground, neutral and hot wire coming to the box.
yes the device must be grounded per NEC code. if the juncrion box is metal you must also sufficiently ground the box using a ground screw or clip. the ground box should be uninterrupted if the device is removed. (the device screws mounted to the box is not a suitable grounding means.
The Plastic box and lid shop
Plastic is synthetic or semi synthetic organic solids that are mold-able. Plastic electric box is one the boxes that is most commonly plastic. Junction box is also one of the common plastic boxes.
It's a Curver Box

Not if its non toxic plastic
No, plastic is an insulator. If the ground pin were made of plastic then there would be no conductivity through the pin to conduct the fault current back to the distribution panel ground. It is this current path that trips the breaker on a ground fault.

No
Plastic is an insulator therefore it is a poor conductor of heat. A plastic box will therefore be able to keep a lot of heat on the inside.
