I then go a few feet horizontally to another junction box with a duplex outlet; repeating to the next box and the next. I have my ground wire from the breaker box, connected to the ground screw on my junction box. This is also pig-tailed to the GFCI outlet, and then to another ground wire which leads to the next box.
Grounding screw colour requirements. Grounding screws are used to ground wires in electrical junction boxes and are typically coloured green for identification purposes. While it is not mandatory for grounding screws to be green, colour-coding them in this way can help to ensure proper wiring and prevent electrical hazards.The in-ground installation for CANTEX PVC junction boxes is also simple, but always be sure to follow all national and regional electrical codes. Article 314-29 of the National Electrical Code states that listed electrical junction boxes may be buried without excavating parts of buildings, sidewalks, other paving, or earth.When conductors are pulled to a 12" × 12" × 4" junction box, a minimum of ? of free conductor shall generally be left for splices or the connection of luminaires or devices.
